Key words: Soybean, drought stress, drought resistance indices, biplot, scatter plot.

Abstract

This experiment was conducted on a research farm of Mahidasht in the west part of Iran in RCBD design with three replications under normal and drought stress conditions. The analysis of variances demonstrated high significant results between studied genotypes on evaluated traits under both conditions. Continue reading
