Notes:
Summary Multivariate techniques were used to classify 125 soybean lines into clusters. Late maturing varieties belonging to maturity group III showed the best adaptation to the ecological conditions of the area when soybeans were sown at early planting dates. A group of experimental lines, the majority of which had semideterminate stem termination with small leaflets and intermediate maturity, were highly productive when grown as a second crop. Some lines of other groups were identified as likely parents for use in a breeding program to improve agronomic characteristics. The identified groups were quite stable in their performance through changes in environmental conditions (years and planting dates). The analyses indicated that some intercorrelated traits can be omitted in future line evaluation.
