Abstract:
In the last few years, the analysis of fatty acids has gained importance because of their nutritional and health implications. This increased attention led to a half dialell crossing design study during 2006 and 2007 seasons in Edirne -Turkey conditions. In this study, 28 F1 maize hybrids were obtained by 8x8 half diallel crossing. In half –diallel maize population, inheritance of linoleic acid content in grains and combining ability were investigated. Mean squares of inbred lines and hybrids were highly significant for all studies traits, indicating the genetic variance among lines. Thi

Abstract:
Abstract A technique based on MIVQUE (minimum variance quadratic unbiased estimation) and the first approximation of the variance of a ratio was used to compare efficiency per unit observation in lowering the variance of estimation of three genetic ratios (single tree heritability, Type B correlation, and dominance-to-additive variance ratio). The efficiency comparisons were made over eight levels of genetic control for three mating designs (half-sib, half-diallel, and circular with four crosses per parent) with variable numbers of parents at two or five locations. The field design was held co

Abstract:
Diallel mating is a frequently used design for estimating the additive and dominance genetic (polygenic) effects involved in quantitative traits observed in the half- and full-sib progenies generated in plant breeding programmes. Gibbs sampling has been used for making statistical inferences for a mixed-inheritance model (MIM) that includes both major genes and polygenes. However, using this approach it has not been possible to incorporate the genetic properties of major genes with the additive and dominance polygenic effects in a diallel mating population.

Abstract Three simple statistical tests (the Bartlett test, the log-ANOVA test, and the Fain test) were investigated for detecting the segregation of major genes controlling a quantitative trait in half-diallel mating populations. Eight experimental diallel progeny populations of loblolly pine (Pinus taeda L.) from a breeding program were analyzed to detect major gene segregation for 6 yr tree height. The results from three simple tests indicated that there could be major gene segregation for 6 yr height in three diallels. Data with different degrees of major and polygenic effects were simulat

Abstract:
A comparison among two forms of half-diallel analysis was made. The different half-diallel techniques used were Griffing's model I, method 2 and 4. These methods of diallel analysis were found to be interrelated. However, as Griffing's model I, method 4 partitioned heterosis into different components as well as gave information about combining ability and this method had certainly some advantages over the other. The results further indicated using parental generations in the second Griffing method may cause biased estimate of the GCA and SCA variances. Thus, using the fourth Griffing method is

Abstract:
This study was conducted to determine the inheritance of common bunt resistance in twelve bread wheat varieties and their half-diallel hybrids in Turkey. The disease ratings were performed on the F2 generations of the hybrids in field conditions. The obtained data were analysed by the χ2 test to determine the effective gene numbers and inheritance type in the disease resistance. In addition, the data were evaluated according to the Jinks-Hayman diallel analyses. In conclusion, it was found that of the twelve wheat parents, four contained three resistance genes and four of them contain two resi

Abstract:
Abstract Female flowering and cone production took place in three Norway spruce progeny tests at ages 17 and 20 years, each planted with full-sib families from a half diallel. The number of cones on individual trees were scored in five classes. More than 50 % of the trees produced cones, and a considerable variation was found among families for the ability to produce cones (precocity) and for the number of clones scored in classes (fruitfulness). Both traits were strongly related to tree heights and diameters at the individual and at the family level. In general, tall trees produced the highes

Abstract:
Summary Half F2 diallel crosses of eight spring cultivars of rapeseed were used in partial circulant diallel analyses to estimate biometric genetic parameters for phenological traits, yield components and seed yield. The greatest variation in the GCA-to-SCA mean square ratio was related to days to flowering, and its lowest variation to days to maturity. A high coefficient of variation of the narrow-sense heritability estimate was obtained for days to maturity, followed by plant height and seed yield. For diallel analysis with a low number of parents, the differences of the heritability estimat
