level that could limit continued breeding success. Introduction of new sources of germplasm into the breeding Asian soybean [Glycine max (L.) Merr.] improvement programs pool may provide the genetic variability to permit conhave been conducted for many years almost completely independent of U.S. breeding programs. Productive, modern Asian cultivars may tinued progress in developing high yieldin...

Genetic maps are essential tools for quantitative trait locus analysis and marker-assisted selection breeding. In order to select parents that are highly heterozygous for genetic mapping, the heterozygosity (HS) of 24 tea cultivars (Camellia sinensis) was analyzed with 72 simple sequence repeat markers. In total, 359 alleles were obtained with an average of 4.99 per marker. The HS varied greatl...

This research was conducted to evaluate 30 sainfoin cultivars in terms of yield, agronomic and morphological traits under water stress condition, using different drought tolerannce indices. A randomized complete block design with three replications was employed during two years at Isfahan University of Technology Research Farm, Isfahan, Iran. Effect of cultivars were significant for all of the ...

Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...

Isoflavones occurring in soybean seed have been thought to have a positive effect on the health of humans, especially in cancer prevention. This positive impact may be a result of their antioxidant properties, estrogenic activity, or a combination of mechanisms. The purpose of this study was to quantify and compare different levels of isoflavones in various Kansas soybean cultivars. Seeds of fo...

Mining elite alleles for grain size and weight is of importance for the improvement of cultivated rice and selection for market demand. In this study, association mapping for grain traits was performed on a selected sample of 628 rice cultivars using 262 SSRs. Grain traits were evaluated by grain length (GL), grain width (GW), grain thickness (GT), grain length to width ratio (GL/GW), and 1000-...
