Oplemenjivanje soje u cilju stvaranja rodnih i stabilnih kultivara soje I grupe zriobe za klimatsko područje istočne Hrvatske

The main objective of our study was to evaluate grain yield stability of some Croatia soybean lines and cultivars of the I maturity group. During the growth season of 1993-1997 both grain yield and yield stability of 29 soybean genotypes (26 lines derived in F4-F6 generations and three cultivars) were investigated by means of microtrials under the climatic conditions of Eastern Croatia. All the lines and cultivars investigated soybean were created at the Osijek Agricultural Institute. Yield stability of the genotypes studied was estimated by the following parameters: mean yield (y), regression of mean yield on an environmental index (b) and the estimation of the remaining interaction component of variance in genotype x environment interaction, due to the contribution of each genotype.
