【 摘 要 】

To obtain national high yielding varieties, it is necessary to evaluate black soybean yield stability in various environments. This study aims to evaluate yield stability and to study its genotype and environment interaction. Genetic material used in this study was five mutant lines of black soybean derived from the irradiation of the Cikuray variety with a dose of 200 Gy. Evaluation of yield stability was carried out jointly with 10 black soybean breeding lines from Balitkabi and Padjadjaran University. Two control varieties of Cikuray and Detam 1 were included in the evaluation. The test was carried out in ten locations across Java Island. Estimation of stability was conducted by the method of Finlay-Wilkinson and Eberhart-Russell. The results showed that genotype and environment significantly contributed to yield variation respectively. Genotype by environment interactions were existed which could affect genotype performance in the testing environment. Four out of five mutant lines showed significant higher yield than other genotypes and control varieties, which ranged from 2.34-2.42 ton/ha. Stability analysis indicated genotypes of G8, G14 and control variety of Detam 1 were stable genotypes and high yield above the general average with average yields of 2.36, 2.09 and 2.21 tons / ha, respectively.
