Abstract:
Sixty-five genotypes (50 crosses and 15 parents) of wheat were studied for generating scientific information on nature and magnitude of genetic variability for designing suitable breeding programme. The parental lines were grown during Rabi 2016-17 and 50 cross combinations among 10 lines and 5 testers were made and then seeds of 15 parental lines and 50 crosses were obtained. During Rabi 2017-18 the parents and F1 s were evaluated in a randomized complete block design in three replications at Seed Breeding Farm, Department of Plant breeding and Genetics, College of Agriculture, JNKVV, Jabalpur. The data were recorded on days to 50% flowering, plant height, number of effective tillers per plant, number of spikes per plant, spike length, number of spikelets per spike, spike weight, number of grains per spike, 1000- grain weight, biological yield per plant, grain yield per plant, harvest index, spike density, canopy temperature and chlorophyll content. Maximum phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were observed for grain yield per plant. High heritability was observed for, days to 50% flowering followed by biological yield per plant. Genetic advance was observed maximum for grain yield per plant.
