چکیده
Abstract Background Shoot architecture is fundamentally crucial to crop growth and productivity. As a key component of shoot architecture, plant height known be controlled by both genetic environmental factors, though specific details remain scarce. Results In this study, 308 representative soybean lines from core collection 168 F 9 progeny were planted at distinct field sites. The results demonstrated the presence significant genotype × environment interaction (G E) effects on traits associated with in natural population. total, 19 loci containing 51 QTLs (quantitative trait locus) for identified across four environments, 23, 13 15 being SH (shoot height), SNN (stem node number) AIL (average internode length), respectively. Significant LOD ranging 2.50 16.46 explained 2.80–26.10% phenotypic variation. Intriguingly, only two loci, Loc11 Loc19–1 , 20 QTLs, simultaneously detected all environments. Pearson correlation analysis PCA (principal analysis) revealed that each five agro-meteorological factors soil properties significantly affected traits, corresponding had additive effects. Among AD day-length), AMaT maximum temperature), pH, AN (available nitrogen) largest impacts height. Therefore, spite uncontrollable might remolded through combined efforts produce superior materials while also optimizing properties. Conclusions Overall, comprehensive set relationships outlined herein among genotypes opens new avenues explore work aiming increase yield improvements architecture.

Epigenetic and genetic components of height regulation
Adult height is a highly heritable trait. Here we identified 31.6 million sequence variants by whole-genome sequencing of 8,453 Icelanders and tested them for association with adult height by imputing them into 88,835 Icelanders. Here we discovered 13 novel height associations by testing four different models including parent-of-origin (|β|=0.4-10.6 cm). The minor alleles of three parent-of-ori...

Soybean has a lot of food and industerial uses. There is a growing demand for various soybean production, due to its nutritional value, wich included high protein and variety of vitamins and minerals. In order to evaluate and compare the yield of pure soybean lines in terms of important agronomic traits and grain yield, 20 top pure lines and two cultivars Sari and Caspian as control, were studi...
