According to computed stability parameters for soybean it could be concluded that a few of studied genotypes (L-4, L-6 and L-10), had stability for yield close to optimum. The regression coefficient lower than 1 was for lines L-1, L-2, L-11, L-12 and the variety Gardos. It means that these lines are adapted to unfavourable conditions, but do not respond to improved conditions. The regression coefficient higher than 1 was detected for lines L-3, L-5, L-7, L-8, L-9 and the variety Kador. These genotypes were low - yielded, under unfavorable conditions, while their yield increased under favourable conditions. Coefficient of correlation, between grain yield and coefficient of regression, amounts to r=0.783, and according to this it could be assumed that genes responsible for stability affect yield of investigated soybean genotypes.
