Abstract
This study was carried out to estimate the phenotypic stability for grain yield of soybean genotypes that planted in four environments. Randomized complete block design with three replicates was used. The genotype consist of six selected genotypes from Lee74 variety and fourteen introduced genotypes belong to different group maturities were used for yield. Three methods were applied to measure the stability regression (bi), variance (S2) and coefficient of variation (C.V%). Stability parameters showed that H143 genotype D`had high stability as compared with other genotypes according to the regression (bi) method, while the result of variance (S2) and coefficient of variability (C.V. %) Showed that the genotype Lorna had high stability.
