Genotype × Environment Interactions and Yield Stability of Food‐Grade Soybean Genotypes

摘要: Soybean [Glycine max (L.) Merr.], an important component of the Asian diet, is gaining popularity as a source vegetable protein and phytochemicals in USA. However, soybean cultivars with desirable agronomic traits biochemical components that enhance quality soyfoods have not been identified for cultivation Twelve genotypes, including three from Japan, were evaluated their performance, genotype × environment (GE) interactions, yield stability at four locations USA 1994 to 1997. At maturity, seed yield, biomass, harvest index (HI), 100-seed dry weight determined using plants harvested middle two rows each plot. Genotypic differences examined significant. The mean across years ranged 2.0 3.0 Mg ha - 1 . Japanese had larger seeds but outyielded by American genotypes 10% up 35% Hutcheson'. effects significantly than location year plant height, weight, HI, biomass or yield. Biomass HI determinants S90-1056, V81-1603, V71-370, 'Enrei', 'Nakasennari', Ware', York' stable years. Hutcheson, York, MD86-5788, Nakasennari, BARC-8 showed environments Nakasennari both yield; therefore, they could be used commercial production breeding suitable tofu preparation.
