Abstract:

Nine corn inbreds were selected from a test on 250 inbreds based on distinctly different response to herbicides. These inbreds showed up to 50,000-fold differences, which varied by inbred and herbicide. Only the inbred GA209 was sensitive to bentazon and the four sulfonylurea herbicides. GA209 and B90 were the most sensitive inbreds to the sulfonylurea herbicides. F2R was generally the most tolerant inbred. The pattern of herbicide tolerance varied greatly. For example, the relative tolerance of F2 to thifensulfuron was 12-fold more than to rimsulfuron while Mo17 was 56-fold more tolerant to r

The Uzbekska bela (Uz.b.) maize variety was crossed to nine inbred lines and genetic difference between this variety and observed maize inbreeds lines was determined. The Uz.b. variety is a heterotic pair interesting for deriving maize hybrids with inbreds of BSSS and Lancaster origin, as well as, with some Yugoslav maize populations (Konjski zub, Domaci tvrdunac). The inbred lines originating from Zambia showed somewhat lower yielding and heterosis percentage in relation to other observed inbred lines in hybrid combinations with the variety Uz.b. .

Fifty-eight sunflower inbreds were evaluated for seventeen morphological parameters during spring 2019 and 2020 to understand the relationships among different traits for facilitating the indirect selection of superior confectionery sunflower inbreds. For confectionery inbreds, seed length is an important trait for making selections since seed length exhibited a negative correlation with seed volume weight which is highly correlated with oil content. Thus inbreds having higher seed length had lower oil content which is a desirable trait for confectionery sunflowers. The investigation also help

Tolerance in some crosses began to break down at application rates approaching twice that registered. Sensitivity was controlled by a single autosomal recessive gene in the inbred Ab18.

Forty six QPM inbreds of diverse origin were genotyped using opaque2 (o2)-specific SSRs viz. umc1066 and phi057, present on exon-1 and exon-6 of the gene, respectively.

A total of two alleles (o2-A and o2-B) of umc1066, and three alleles (o2-C, o2-D and o2-E) of phi057 were identified. o2-A allele (93.48%) was the most abundant, while o2-B allele was observed only in 6.52% of the inbreds. For phi057 locus, o2-E allele had the highest frequency (80.17%), followed by o2-D (19.57%) and o2-C (2.17%).

Commercial bulb-onion (Allium cepa L.) growers often complain that hybrids they have grown successfully for a few years fail to perform at the expected level. Inbreds used to produce hybrid-onion seed rarely have been self-pollinated for more than two generations and retain a high level of heterozygosity. Over time, selection, drift, or contamination of inbreds may contribute to disappointing hybrid performance.

Abstract:

CO388 and CO389 are short-season corn inbred lines with improved resistance to silk infection by Fusarium graminearum. These inbreds are the first to be released from a public breeding program with improved resistance to ear rot; they can be used by maize breeders as a source of resistance. Both inbreds exhibit good combining ability and average to superior lodging resistance in hybrids. Key words: Corn, maize, Zea mays, cultivar description, ear rot, Fusarium

Abstract:

Extensive field and greenhouse studies were done to characterize varietal response of three recently commercialized sulfonylurea corn herbicides: nicosulfuron, primisulfuron, and thifensulfuron. Most of the 94 varieties tested were highly tolerant to these herbicides. The 37 inbreds represented all major inbred families now used in hybrid seed production as well as several sensitive experimentals. Twenty-one defined hybrids from these inbreds as well as 36 commercially coded hybrids were also tested. Sensitive inbreds produced tolerant hybrids when crossed with tolerant inbreds.

In temperate world-wide regions, maize kernels are often infected with the fumonisin-producing fungus Fusarium verticillioides which poses food and feed threats to animals and humans.

Due to an unknown mechanism of genetic control and great environmental effects in the process of trait expression, morphological markers are often considered unreliable indicators of genetic relationships. Morphological characterization of 19 maize inbreds was done according to the UPOV descriptor, while molecular characterization was performed with RAPD markers. Based on the estimation of phenotypes according to the UPOV descriptor, the squared Euclidean distance was calculated and then, on the basis of this distance, a morphological similarity matrix was formed.
