Abstract:
Therefore, the experiment was conducted during Rabi, 2022 at College Farm, M.S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Paralakhemundi, Odisha, India to estimate the genetic variability in 52 inbred lines tested in randomized block design with three replications. The data was recorded for days to 50% tasseling, days to 50% silking, anthesis-silking interval, days to maturity, plant height, ear height, number of ears per plant, ear length, ear girth, number of kernel rows per ear, number of kernels per row, shelling percentage, 100 kernel weight, protein content, oil content and grain yield per plant. Analysis of variance indicated the existence of significant differences among the genotypes for all the traits studied. High GCV and PCV values were observed for anthesis-silking interval. High heritability coupled with high genetic advance as percent of mean was observed for anthesis-silking interval, number of kernel rows per ear, number of kernels per row, 100 kernel weight, oil content and grain yield per plant suggesting the role of additive genes in governing the inheritance of these traits which could be improved through simple selection.
