Abstract:
To determine the degree of heterosis over the mid parent, over the better parent, and over the standard check (economic heterosis) for grain yield per plant, a study using a Line x Tester Mating Design with ten different genotypes of green gram (Vigna radiate L. Wilzeck) along with one check and their 24 F1 hybrids was conducted. For grain production per plant and other yield components, the cross ML-2333 x TARM-1 showed the highest average heterosis (48.61%), heterobeltiosis (28.78%), and SH (99.67%). The hybrid ML-2333 x TARM-1 registered the greatest SH for grain yield per plant (99.67%) followed by NVL-641 x TARM-1 (80.13%). Days to flowering and days to maturity had low heterosis values, whereas other characters had intermediate heterosis values. The crosses, ML-2333 x TARM-1, NVL-641 x TARM-1, PUSA-1477 x TARM-1, ML-2056 x TARM-1 and ML-2056 x Karjat local were found to be the most promising combination for most of the yield contributing traits.
