Multi-environmental evaluation of vegetable soybean for adaptation and stability in Benin

Vegetable soybean (Glycine max L. Merr.) is a highly nutritious crop in Africa whose attributes make it product of choice to formulate diets with numerous human health benefits. The still novel West Africa, but making inroads many countries the region. objective this study was evaluate selected vegetable varieties for agronomic performance and stability fresh pod yield across Benin. Thirty-five were planted at three locations, namely Calavi, Grand-Popo Sèmè, two seasons. There significant variation (P < 0.05 ; P< 0.01 P 0.001) among genotypes most quantitative traits; environmental GEI effects on 0.001). Genotype Maksoy 3N (15.9 t ha-1) had highest yield; while genotype AGS466 stable environments. Based GGE, Sèmè-2 ideal environment growing confirmed that well adapted be grown Benin AGS466, AGS346 Ashorowase are candidates wide cultivation country. Also, grain (S1079-6-7 3N) suited produce Benin.
