Abstract Soybean is the world’s leading source of vegetable protein and demand for its seed continues to grow. Breeders have successfully increased soybean yield, but genetic architecture yield key agronomic traits poorly understood. We developed a 40-mating nested association mapping (NAM) population 5,600 inbred lines that were characterized by single nucleotide polymorphism (SNP) markers six in field trials 22 environments. Analysis agronomic, SNP data revealed 23 significant marker-trait...
Physiological variation among populations of Heterodera glycines Ichinohe, the soybean cyst nematode, has been a problem for [ Glycine max (L.) Merr.] growers and scientists. These have classified into 16 races, but system still leaves ambiguity, especially in characterization resistance. Two schemes are proposed: one to classify nematoder aces other designate response nematode. The existing race by Riggs Schmitt serves as basis differentiating H. , with PI 437654 added an additional...
Growing conditions in the U.S. Midsouth allow for large soybean [ Glycine max L.

Abstract Background Soybean ( Glycine max [L] Merr.) seed isoflavones have long been considered a desirable trait to target in selection programs for their contribution human health and plant defense systems. However, attempts modify isoflavone contents not always produced the expected results because genetic basis is polygenic complex. Undoubtedly, extreme variability that display over environments has obscured our understanding of genetics involved. Results In this study, mapping...
Charcoal rot (CR), caused by the fungus Macrophomina phaseolina (Tassi) Goid. is a pervasive disease of economic significance on soybeans (Glycine max (L.) Merr.). Similarly, drought leading cause yield loss in soybean worldwide. In this study, CR severity and seed were determined irrigated non-irrigated environments 2011, 2012, 2013 for thirteen genotypes, nine which previously to be tolerant (DT). The objectives determine putative DT genotypes over-all effect environments. Colony Forming...
Seed composition is one of the most important determinants economic values in soybean. The quality and quantity different seed components, such as oil, protein, carbohydrates, are crucial ingredients food, feed, numerous industrial products. Soybean researchers have successfully developed utilized a diverse set molecular markers for trait improvement soybean breeding programs. It imperative to design develop assays that accurate, robust, high-throughput, cost-effective, available on common...
Planting date is one of the main factors affecting soybean (Glycine max [L.] Merr.) yield. Environmental conditions in US Midsouth allow for planting dates from late March through early July, and maturity groups (MGs) ranging 3 to 6. However, complexity interactions among date, MG, environment makes selection an optimum MG cultivar difficult. A regional 3‐yr study, conducted at eight locations with latitudes 30.6 38.9°N, MGs 6, was used examine relationship between relative yield day. The...
The relatively low genetic variation of current US soybean [ Glycine max (L.) Merr.] cultivars constrains the improvement grain yield and other agronomic seed composition traits.
