Twenty black gram genotypes were evaluated at five different locations of middle Gujarat in kharif 2016 to assess the genotype x environmental interactions in RBD design with two replications. The data were analyzed according to the AMMI model and AMMI based stability measures (ASV Wi(AMMI) and ASTABi). Analysis of variance on the data pooled over locations and G x E interaction was found significant indicated genotypes performed differently in different locations. IPCA1 and IPCA2 were found significant in AMMI model and both combined accounted for by 78.7% variance of GEI. Environments viz., Devgadhbaria, Derol and Dahod were found high yielding environments whereas Vadodara and Jabugam were low yielding environments. Genotypes G3, G18, G16 and G10 gave high yield in environment E3, E1 & E4, E5 and E2, respectively as they were vertex genotypes in polygon of AMMI2. According to AMMI model, ASV, Wi(AMMI) and ASTABi, G19 was found stable and high yielding genotype, whereas G16 was unstable genotypes.

GAU 4 is a high yielding, YMVD resistance variety developed through selection from germplasm maintained (GP No. 6) at ARS, AAU, Jabugam, Dist : Chotta Udaipur, Gujarat and tested as JAUG 2 in trial. JAUG 2 recorded 21.03 and 24.48 per cent higher yield (961 kg/ha) over the checks T 9 and GU 1, respectively under middle Gujarat. In kharif season, JAUG 2 recorded 1005 kg/ha seed yield which was 19.08 and 23.92 per cent higher over T 9 and GU 1, respectively under middle Gujarat. In summer, JAUG 2 recorded 864 kg/ha seed yield which was 22.21 and 23.42 per cent higher over T 9 and GU 1, respectively under middle Gujarat. The proposed genotype JAUG 2 has semi-erect plant type and medium maturity duration. It has deltoid leaf shape, green hairy pod with 5-7 seeds per pod, dark black and medium seed size (seed index.:4-5 g). On quality point of view, this genotype contains 24.66% protein, 55.58% total carbohydrate, 4.77% total soluble sugar, 0.946% phenol and 8.89 mg/100g flavonoid, which is comparable to check varieties T 9 and GU 1. In mineral contains 49.97 Fe, 29.28 Zn and 7.29 Cu mg kg-1 which is higher than both check varieties viz., T 9 and GU1. The genotype JAUG 2 is found resistant to Yellow Mosaic Disease under natural field condition as compared to check T 9 and GU 1. The special feature of newly develop variety is medium maturity, semi-erect plant type, hairy pod, dark black, drum shape seed, resistant to YMD with higher yield.
