Determination of Variability, Heritability, Genetic Advance and Their Interrelationships in Rabi Sorghum (Sorghum bicolor L. Moench) for Various Yield and Yield Contributing Traits under Drought Conditions | Chapter 1 | Current Topics in Agricultural Sciences Vol. 8

Studying the genetic variability characteristics is important for the efficient selection of crop species. Any breeding programme for crop improvement must have desired variation present, as well as a certain degree of heritable variation. As a result, every breeding effort for crop improvement is strongly reliant on genetic diversity, heritability, and genetic advancement. At the Sorghum Research Station, V.N.M.K.V., Parbhani, the genetic variability research for yield and yield contributing factors in 37 genotypes of rabi sorghum with three checks, M 35-1, Phule Suchitra, and CSV-22-R, was conducted during rabi 2019. To estimate the genetic variability for quantitative characteristics, the treatments were examined, and data for 11 traits were collected using a randomised block design with three replications. The discovery of extremely significant genotype differences reveals a substantial degree of variability in all 11 characteristics examined. Greater estimates of phenotypic coefficients of variation are obtained, and these estimates are of lower size, when phenotypic coefficients of variation are compared to genotypic coefficients of variation. Among the forty genotypes examined, VJV 107, VJV 106, PEC 30, RSV 1921, RSV 1945, and RSV 1984 were considered the superior genotypes since they outperformed the others. The goal of the current study was to calculate the genetic variability for quantitative characteristics.
