In: Minufiya Journal of Agricultural Research 2002. v.27(2)Summary: This investigation was carried out at Sakha, Zahoura, Mallawy and Shandaweel Research Stations during the two successive seasons 1999 and 2000. Three soybean genotypes along with five cultivars were used to evaluate phenotypic and genotypic stability for these genotypes across locations and years. The combined analysis of seed yield over locations suggested that some varieties were more stable in yield performance than others. It can be concluded that, three genotypes namely: Giza 35, H2L12and Giza 111 had a high seed yield performance and high stability at phenotypic and genotypic levels and it could be grown over wide range of environments. The estimates of phenotypic correlation coefficients indicated that seed yield (ton/feddan) was highly significant positive corrletated with number of pods and seed yield/plant, hence Seed yield by it self may not be the best criteria for selection.
