Abstract:
Six S5 lines of maize, with differences for lysine and oil contents in grains, were used to carry out a complete series of diallelic crosses. The resulting 15 hybrids were grown in a field at two nitrogen levels (10 and 130 kg N ha-1). The general combining ability (GCA) and specific combining ability (SCA) were obtained by using the method 4, model I of Griffing for grain yield, and grain lysine and oil contents. Significant (p < 0.001) interaction was observed between GCA and N levels for grain yield, indicating the selection of different lines for each N level. This interaction was not significant for lysine content, but there were significant effects of GCA for this trait at both N levels (p < 0.1). Significant effects were not observed for GCA or SCA for oil content, however a positive correlation was observed between lysine and oil contents in the hybrids, in the lines and even in the control cultivars. The results indicate the effectiveness of selection for lysine content, irrespective of N level, in the studied non-opaque maize lines, and the possibility of achieving both high lysine and oil content in grains.

In breeding programs, it is important to use viable alternatives to reduce cost and time spent on population evaluations, combined with adequate statistical methodologies applying the maximum information available. Within this context, this work aimed to: i) study the genetic control of popping capacity and grain yield in popcorn; ii) predict the effects of general combining ability (GCA) and specific combining ability (SCA), applying mixed model analysis; iii) evaluate the performance per se of the lines used in hybrid crosses; and iv) evaluate the efficiency of Best Linear Unbiased-Prediction (BLUP) in predicting the performance of non crossed hybrids in diallelic analysis. Data from experiment evaluations of intra-population diallels of the Beija-Flor and Viçosa popcorn populations were used in the analyses. Eighteen S6 Beija-Flor elite lines were analyzed in ten environments and 29 S6 Viçosa elite lines in eight environments. Combined analyses were carried out, considering all the environments, with the additive model being adopted. The software ASREML was used in all analyses. GCA variability was verified both for grain yield and popping capacity. A significant SCA variability was verified in Beija-Flor for the two variables. In Viçosa, SCA was significant at 8% for grain yield while for popping capacity, the presence of additive effects was practically verified in its expression. Through the incorporation of sibling relationships in diallelic analysis, SCA values of combination of a line with itself (sjj) were predicted, without such cross being carried out. The use of BLUP/REML allowed the prediction of over 43 to 210% hybrid combinations, if compared only to the hybrid observed. Based on hybrid predictions, promising crosses were identified both for grain yield and popping capacity, being observed that the inclusion of a pedigree seems to make the analyses more accurate, as compared to the model not using this information. The performance per se and under S6 family crosses showed moderate correlations (r = 0.53) for popping capacity, showing that families with high popping capacity GCA can be selected, based on their performance per se. Aiming to obtain information on the efficiency in predicting S6 families based on performance per se and on S3 family crosses, a positive correlation (r = 0.76) was found for production between the GCA of top cross hybrids of the S3 families and the S6.family hybrids. When verifying BLUP efficiency in the prediction of non crossed hybrids, moderate to high Pearson and Spearman correlations were found among the predicted and observed values. Prediction of hybrids in the absence of dominance (popping capacity, r = 0.88) was more efficient than in the presence of dominance (grain yield, r = 0.53). The overall results showed that the use of mixed models is an efficient alternative in diallelic analysis, providing good precision in estimating genetic parameters, besides allowing the prediction of non crossed hybrids.
Em programas de melhoramento é importante o uso de alternativas viáveis para redução de custos e tempo nas avaliações de populações, aliadas ao uso de metodologias estatísticas adequadas, que aproveitem ao máximo as informações disponíveis. Neste contexto, o presente trabalho teve como objetivos: i) estudar o controle genético da capacidade de expansão e produção de grãos em milho-pipoca; ii) predizer os efeitos da capacidade geral de combinação (CGC) e da capacidade específica de combinação (CEC) por meio da análise de modelos mistos; iii) avaliar o desempenho per se das linhagens utilizadas nos cruzamentos híbridos; iv) avaliar a eficiência do BLUP na predição do desempenho de híbridos não realizados na análise dialélica. Nas análises, foram utilizados dados de experimentos de avaliação de dialelos intrapopulacionais das populações de milho-pipoca Beija-Flor e Viçosa. Foram analisadas 18 linhagens elites S6 de Beija-Flor, em 10 ambientes, e 29 linhagens elites S6 de Viçosa, em 8 ambientes. Foram realizadas análises conjuntas, considerando todos os ambientes, sendo adotado o modelo aditivo-dominante. Em todas as análises foi utilizado o software ASREML. Foi verificada variabilidade para CGC tanto para produção como para capacidade de expansão. Para CEC houve variabilidade significativa em Beija-Flor para as duas variáveis. Em Viçosa, a CEC foi significativa a 8% para produção de grãos, enquanto para capacidade de expansão foi verificada praticamente a presença de efeitos aditivos na sua expressão. Por meio da incorporação de informações de parentesco na análise dialélica, valores de capacidade específica de combinação de uma linhagem com ela mesma (sjj) foram preditos, sem que este cruzamento tenha sido realizado. Com o uso do BLUP/REML foi possível predizer de 43% a 210% a mais de combinações híbridas, se comparada somente aos híbridos observados. A partir das predições dos híbridos, cruzamentos promissores foram identificados tanto para produção de grãos como para capacidade de expansão, sendo que a inclusão do pedigree parece deixar as análises mais acuradas, em comparação ao modelo sem uso destas informações. O desempenho per se e em cruzamento de famílias S6 evidenciaram correlações moderadas (r=0,53) para capacidade de expansão, mostrando ser possível selecionar famílias com alta CGC em capacidade de expansão a partir do desempenho per se de suas famílias. Visando obter informações sobre a eficiência da predição de famílias S6 a partir do desempenho per se e em cruzamento de famílias S3, foi encontrada correlação positiva (r=0,76) para produção, entre a CGC dos híbridos topcross de famílias S3 e híbridos de famílias S6. Ao verificar a eficiência do BLUP na predição de híbridos não realizados, foram encontradas correlações de Pearson e Spearman de moderada a elevadas, entre os valores preditos e observados. A predição de híbridos não realizados na ausência de dominância (capacidade de expansão, r=0,88) foi mais eficiente, em comparação à presença de dominância (produção de grãos, r=0,53). Os resultados gerais demonstraram que o uso de modelos mistos é uma alternativa eficiente na análise dialélica, proporcionando boa precisão nas estimações dos parâmetros genéticos, além de permitir a previsão de cruzamentos não realizados.

Abstract:

AbstractBIN XIANG Genetic Analysis of Diallel Tests of Loblolly Pine (Pinus taeda L.) (Under the direction of Dr. Bailian Li)A new approach was developed for analyzing diallel tests with SAS PROC MIXED and PROC IML. The new method can estimate variance components, obtain BLUE (best linear unbiased estimators) of fixed effects and BLUP (best linear unbiased predictors) of random genetic effects simultaneously. A new formula based on BLUP was further developed to predict individual tree breeding values. This new analytical method was validated using computer simulation and was compared with other existing programs. To analyze disconnected diallel mating designs with more than one diallel, simulated data generated with known parameters were analyzed using BLUP to compare three alternative models, which include diallel as fixed effect (Model 1), random effect (Model 2) or no diallel effect (Model 3). Both Model 1 and Model 3 produced unbiased GCA (general combining ability) variance estimates, while Model 2 resulted in downward biased GCA variance estimate. The accuracy of BLUP prediction for three models was very close, with Model 3 slightly better than the other two. Statistical approaches were also evaluated for combining multiple disconnected diallel test series in a given region. The best GCA sample variance prediction in the class of linear combination of local variance estimates was derived. Simulation study showed that a checklot adjustment was very critical to improve the prediction of genetic values obtained using BLUP analysis. Additional adjustment with improved GCA sample variance prediction could improve the correlation slightly beyond checklot adjustment.Analysis of annual measurement through age 8 from a total of 275 parents, 690 full-sib families from 23 diallel tests of loblolly pine in Northern, Coastal and Piedmont test regions showed: 1) dominance variance was small (20-40% of total genetic variance) relative to additive variance; 2) heritability increased over time, and the magnitude of heritabilities for diameter at breast height (DBH) and volume was comparable with the corresponding heritabilities for height; 3) DBH and volume had higher genetic correlation with 8-year volume than height. Genetic gain prediction in year-8 volume for selection on height and volume indicated that: 1) selection on volume yielded more gain than selection on height; 2) Coastal population had the greatest correlated response, followed by Piedmont and Northern population; 3) family plus within family selection based on total genetic component can capture the most genetic gain; 4) for all selection methods, additional gain (10-40%) can be achieved by capturing non-additive genetic component.Selection efficiency study of height and volume for three test regions indicated that earlier selection appeared to be more efficient than direct selection on year-8 volume in most selection methods. Family selection can be performed at age 2 or 3 for height and at age 4 for DBH and volume. Combined selection (family plus within family) was highly efficient at age 3 or 4.

Thesis (M.Sc. (Animal Production)) --University of Limpopo, 2011
Crossbreeding is one of the tools for exploiting genetic variation. The main purpose of crossing chickens is to produce superior crosses (i.e. make use of hybrid vigor), improve fitness and fertility traits.This study was carried out at the University of Limpopo Experimental Farm located in Limpopo, South Africa. The objective of the study was to evaluate the growth performance of differentpurebred and crossbred chicken genotypes. A 3 x 3 complete diallel mating system involving two indigenous breeds namely Venda (V) and Naked Neck (N) and one commercial broiler breed, Ross 308 (R), were used to produce three purebred (V x V, N x N, R x R), three crossbreds (R x V, R x N, V x N) and three reciprocals (V x R, N x R, N x V).The nine genetic groups were rearedfrom hatch to 13 weeks of age in a deep litter open house. Body weights of 180 chicks (20 chicks per genetic group), recorded at 0, 3, 5, 7, 9, 11, and 13 weeks of age, were used to estimate heterosis, general (GCA) and specific (SCA) combining abilities, maternal ability and reciprocal or sex-linked effects on body weights. Results showed that the Ross 308 had the heaviest body weight at all weeks of measurement except for hatch. With respect to crosses, the reciprocal V x R and the cross R x V had the heaviest body weights at 13 weeks (2448.40 and 2131.50 grams, respectively), although N x R had heavier body weight than R x V at all weeks of measurement except for hatch and 13th week. Results of heterosis estimates indicated that crossing between Venda male and Ross 308 female as well as between the Venda male and Naked Neck femalegave the highest heterotic effects for body weight(11.01% and 10.33%, respectively).General Combining Ability was significant (P≤0.01) for body weight from hatch to 13 weeks of age while SCA and Reciprocal effects (RE) were both significant (P≤0.05) for body weight at all ages of measurement except for hatch weight. The Ross 308 chicken gave the highest positive effect of GCA for body weight except for hatch weight. Venda sire crossed with Naked Neck dams gave the highest and positive effects of SCA for body weight. Naked Neck sire crossed with Venda dams had the highest positive estimate of RE for body weight except for the 13th week. Results show that using Venda chickens as a paternal breed in crossing with Naked Neck and Ross 308 females may improve growth performance of indigenous chickens.

Abstract:
Improving protein quality and identifying superior inbreds and hybrids are significant challenges in commercial maize breeding programs. These two problems were addressed in separate studies on inbreds and hybrids from a complete diallel cross of 12 elite proprietary inbred lines of maize evaluated in field trials in two locations for two years. One of the inbreds (WI) was a novel source of high quality protein obtained from Wilson Seeds, Inc. in Harlan, Iowa. In the first study, diallel analyses were used to study combining ability and types of gene action important in the inheritance of protein content, grain yield, grain moisture at harvest, time to silk, kernel hardness, and density. General combining ability (GCA) and specific combining ability (SCA) effects were highly significant for all traits indicating presence of both additive and non-additive effects, respectively. Reciprocal effects (REe), often assumed to be absent in maize diallel studies, were significant for grain yield and protein concentration, suggesting that choice of female parent may be important for these traits. Ratios expressing the relative importance of GCA and SCA indicated that protein concentration is controlled primarily by additive gene action. In the second study, restriction fragment length polymorphism (RFLP) data were obtained for the 12 inbreds using 42 genomic clones each with four restriction enzymes. Modified Roger's distances were calculated and used in cluster analyses for heterotic grouping of the inbreds. Two measures of level of heterozygosity and hybrid value were evaluated as means of predicting Fl performance of hybrids in the complete diallel set of hybrids and in groups of hybrids representing crosses between and within heterotic groups. Results from this study confirm those of previous investigations with respect to prediction of hybrid performance when comparable groupings of crosses between related and unrelated lines were evaluated. This study further indicates that RFLPs may also be useful for prediction of hybrid performance in situations typical of early generations of many maize breeding programs where recombinant inbreds are testcrossed to a common tester inbred.

L'analyse de la variabilite phenotypique dans un plan de croisement diallele chez le merisier montre que la selection sur tests clonaux des clones installes en vergers a graines et des parents des futures generations d'amelioration devrait donner de bons resultats. Les puissances de detection de qtl sont comparees pour des populations obtenues par divers plans de croisements. Les resultats montrent que pour echantillonner correctement la variance a un qtl additif, il faut utiliser une population issue de 4 a 6 parents au minimum, mais obtenue selon n'importe quel plan de croisements. L'interet et la mise en pratique du marquage des extremes dans une population comprenant plusieurs familles sont examines. L'efficacite du marquage des extremes est etudiee pour la detection de qtl affectant le caractere pour lequel les individus extremes sont marques ou un autre caractere. Une methode simple d'analyse des donnees est developpee pour bien prendre en compte la particularite des donnees obtenues par marquage des extremes. En consequence de ces resultats, un plan d'experience pour la recherche de qtl de resistance a l'anthracnose chez le merisier comprenant des descendances issues de 5 parents formant un plan de croisements diallele a ete choisi et les individus extremes de ces descendances seront marques. Finalement, les problemes statistiques lies a la mise en pratique de la selection assistee par marqueurs (sam) chez les arbres forestiers ont ete etudies et l'efficacite economique de la sam a ete evaluee dans le cadre de la selection de clones au sein de familles de pleins-freres. La sam dans ce cadre peut etre plus efficace que la selection phenotypique a moyens egaux, d'autant plus que la population d'amelioration est de taille importante.

Abstract: The success in the maize breeding programs depends of the identification of inbred lines with good combining ability for hybrids production. The objective of this study was to identify inbred lines with good combining ability using partial diallel. Were evaluated 16 inbred lines of the maize populations Dentado and Flintisa in a partial diallel where each inbred line was crossed with the eight of the other population, resulting in 64 hybrids. The 64 hybrids were evaluated in a triple lattice in two crop season (sowing on 04/07/2009 and 16/11/2009). At the end of each repetition of the lattice were placed commercial controls XB 6012, AG 9010, XB 7253 and BG 7049, seeking a simple comparison with the experimental hybrids. Were measured the female flowering, plant height, ear height, lodging and grain yield. The hybrids 4Dx6F, 7Dx4F, 7Dx8F and 7Dx8F were appointed to continue in program as promising for the two crop seasons. The hybrids 1Dx6F, 2Dx8F, 5Dx5F, 7Dx1F, e 7Dx3F were appointed to continue in program as promising for the first crop season. The hybrids 3Dx2F, 3Dx3F, 2Dx7F, 5Dx6F, 6Dx3F, 7Dx4F, 2Dx5F, 2Dx6F, 7Dx2F e 7Dx3F were appointed to continue the program as promising for the second crop season.

Abstract:
Fiber quality data from five upland cotton (Gossypium hirsutum L.) genotypes, which were grown at College Station, TX during 2001 and 2002, were subjected to diallel and generation means analyses to determine the potential for improvement of fiber length and to determine the inheritance of length distribution data. Four near-long staple (NLS) upland cotton genotypes and one short-staple genotype were crossed in all combinations, excluding reciprocals. Estimates of general (GCA) and specific combining ability (SCA) for fiber length based on Griffing’s diallel Model I, Method 4 were calculated for high volume instrumentation (HVI) upper-half mean (UHM) fiber length and advance fiber information system (AFIS) mean fiber length by weight (FLw), mean fiber length by number (FLn), upper quartile length by weight (Uqlw), fiber length distribution cross entropy (using 3 different standard or check distributions - CEA, CEB, and CEC), fiber length distribution kurtosis (FLwKurt), and fiber length distribution skewness (FLwSkew) for FLw. Across environments, GCA effects were significant for fiber length measurements of UHM, FLw, FLn, Uqlw, and SFCw and distribution measurements of CEA, CEB, FLwKurt, and FLwSkew. On the basis of GCA effects, TAM 94L-25 was the best parent to be used in a cross to improve upland fiber length, while Acala 1517-99 was the parent of choice to improve distribution among the 4 parents tested. The inheritance of AFIS fiber length measurements and distribution data was estimated using parents, F1, F2, and backcross generations. The magnitude and significance of the estimates for non-allelic effects in the parental combinations suggest that epistatic gene effects are present and important in the basic mechanism of AFIS fiber length and length distribution inheritance for the populations studied. Gene effects and variances for all AFIS fiber length and distribution data measurements were inherited differently in different environments and specific parental combination, suggesting environmentally specific mechanisms. Developing genotypes with enhanced fiber length and an optimal fiber length distribution should be a priority to improve spinning performance and product quality of U.S. upland cotton.

Abstract:
In different crop plants, combining ability and heterosis are used as important diagnostic tools for assessing the performance of parental genotypes and their hybrids. This research aimed to evaluate heterotic and combining ability effects in the diallel crosses of melon (Cucumis melo L.) for yield- and quality-related traits. Seven melon (C. melo L.) genotypes were grown and crossed in a complete diallel fashion to produce F1 hybrids. During the 2019 crop season, 49 melon genotypes (7 parents + 42 F1 hybrids) were grown in a randomized complete block design with three replications. Observations were made for seven characters. Analysis of variance revealed significant (P ≤ 0.01) differences among the melon genotypes for harvest age, fruit flesh thickness, fruit total soluble solids, fruit length, and fruit diameter and merely significant differences (P ≤ 0.05) for fruit weight. Combining ability analysis revealed that mean squares due to general combining ability (GCA) were significant for fruit diameter but were nonsignificant for all other traits. However, mean squares due to specific combining ability (SCA) were significant for all traits. The parental genotypes PK-165, PK-464, and PK-669 exhibited the highest and desirable GCA effects for yield and quality traits. Hence, these genotypes could be used to generate high-yielding hybrid/open-pollinated cultivars. GCA:SCA ratios further revealed that the traits of harvest age, fruit flesh thickness, fruit total soluble solids, fruit length, and fruit weight were controlled by dominant gene action, whereas fruit diameter was managed by additive and dominant genes. The majority of the traits were controlled by nonadditive gene action, verifying that the said breeding material could be efficiently used for the production of hybrid cultivars on the basis of heterotic effects.

Abstract:
The phenotypic analysis of new candidate varieties at multiple locations could provide information on the stability of their genotypes. We evaluated the stability of 11 maize hybrid candidates in five districts in East Java Province, Indonesia. Maize hybrids with high yield potential and early maturity traits derived from a diallel cross were planted in a randomized complete block design with two checks (Srikandi Kuning and BISI-2) as a single factor with four replicates. The observed traits were grain yield per hectare and harvest age. The effects of environment, genotype, and genotype × environment interaction on yield were highly significant (P < 0.01). KTM-1, KTM-2, KTM-4, KTM-5, and KTM-6 showed higher average grain yield per hectare than the checks (Srikandi Kuning = 8.49 ton ha−1 and BISI-2 = 7.32 ton ha−1) at five different locations. The average harvest age of 11 candidates was less than 100 days. KTM-4 and KTM-5 had production yields that were higher than the average yield of all genotypes in all environments (Yi > 7.78 tons ha−1) and were considered stable on the basis of three stability parameters, i.e., Finlay–Wilkinson, Eberhart–Russell, and additive main effect multiplicative interaction (AMMI). KTM-2 had the highest yield among all tested genotypes (9.33 ton ha−1) and was considered as stable on the basis of AMMI but not on the basis of Finlay–Wilkinson and Eberhart–Russell. KTM-1 performed well only in Pamekasan, whereas KTM-6 performed well only in Sampang. Thus, these two genotypes could be targeted for these specific locations.
