Abstract:
Genetic variability was assessed in newly developed lines in bread wheat (Triticum aestivum L.) germplasms with 50 genotypes of wheat collected from office of Wheat Specialist, Agricultural Research Station, Niphad (MPKV. Rahuri) during Rabi, 2019-20. The analysis of variance for eight characters indicated the appreciable amount of variability was present in the material under study. Genotypic coefficient of variation (GCV) was lower than the phenotypic coefficient of variation (PCV) for all the characters under study. The high GCV and PCV was observed for grain yield per plot, number of spikelets per earhead, 1000 grain weight, number of grains per earhead, spike length and plant height. The characters such as grain yield per plot, 1000 grain weight, number of spikelets per earhead, and number of grains per earhead exhibited high heritability coupled with high genetic advance indicating that most likely heritability is due to additive gene effect and selection may be effective for these characters. High heritability coupled with moderate genetic advance was observed in plant height, spike length, days to 50 percent flowering indicating that additive and non-additive both gene action were present.
