چکیده
Abstract Increasing soybean yield plays a key role in meeting the high demand for protein Europe and other countries. The aim of this study was to dissect genetic architecture underlying seed yield, plant height, thousand‐seed weight early‐maturing soybean. To end, we performed QTL mapping based on 944 RILs derived from half‐diallel crossing design five parents. We identified eight each four agronomic traits some explained considerable proportion genotypic variance. three major showed pleiotropic effects two or more traits. Fine characterization revealed maturity genes E1 E3 , stem growth habit gene Dt2 as likely candidates these QTL. In general, allele increasing also resulted taller plants, which needs be considered during selection due an increased risk lodging. Collectively, our results underline strong effect loci like range including making them attractive targets marker‐assisted selection.

Simultaneous Selection for Seed Yield and Agronomic Traits in Sunflower
Selection of high yielding genotypes is very important in sunflower. Thus, 24 new sunflower hybrids along with Golsa cultivar were evaluated in a simple lattice design (5×5) with two replications in the Agriculture Research Station of Gorgan, north of Iran, during 2020. The genotype by yield × trait (GYT) biplot method was used in order to study the relationships between different traits and to...

Extended Abstract Introduction and Objective: Wheat is one of the most important crops in the world that plays a key role in ensuring food security. In wheat breeding programs, selection of genotypes with desirable agronomic traits and high yield potential have always been the goal of plant breeders. Increasing the selection efficiency for grain yield depends on genetic knowledge from morpholo...
