Soybean Cultivar Evaluation via GGE Biplot Analysis

Abstract

ABSTRACT Multi-environment trials (MET) are an important activity in agriculture to identify superior cultivars for production. Visual evaluation of MET data via GGEbiplot software makes the cultivar recommendation easy. Our objectives were to evaluate performance of 100 soybean [Glycine max (L.) Merr.] cultivars belonging to five maturity groups (MG II through MG VI) from MET data from Virginia. Analyses of variance revealed significant differences among cultivars in MG II, MG IV, and MG V. The study was conducted in 1993 and 1994 at two locations [Petersburg (PBG) and Suffolk (SFK), Virginia]. Cultivar-by-environment interaction was only significant for MG IV and MG V. In MG II, the highest yielding cultivars were: ‘CN-290’ (at Suffolk in 1993), ‘Sloan’ (at Petersburg in 1993 and 1994), and ‘Vickery’ (at Suffolk in 1994). In MG IV, ‘Union’ was the best cultivar for 93PBG and 94SFK. ‘Stafford’ was superior at 93SFK and Cutler at 94PBG. Being closest to the ideal cultivar, ‘Union’, ‘Morgan’, and ‘Egyptian...
