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. Recently, a substantial effort has been undertaken to introduce novel diversity present in wild ( soja Siebold & Zucc.) into elite cultivars, both public private breeding programs. objectives this research were evaluate phenotypic within collection 80 G. plant introductions (PIs) USDA National Genetic Resources Program analyze correlations between Field tests conducted Missouri North Carolina during 3 yr (2013, 2014, 2015) randomized complete block design. data collected included maturity date, weight, concentration protein, oil, essential amino acids, fatty acid, soluble carbohydrates. We found that genotype was significant P < 0.0001) source for protein oil carbohydrates, observed numerous PIs generally had lower higher contents linolenic raffinose, stachyose, oleic acid than cultivated lines. information study will be invaluable guiding breeders geneticists selecting promising cultivar improvement.
