Assessment of genetic variability, heritability and genetic advance in wheat (Triticum aestivum L.) under sodic soil

Abstract

The experiment on 108 treatments of wheat along with 80 F1’s, 24 parental lines (20 females + 4 males) and four standard variety (KH-65, KRL-1702, KRL-1714, NW-1014) of wheat was conducted to work out the genetic variability, heritability and genetic advance effects of their various attributes on grain yield. The high estimates (>15%) of phenotypic (PCV) and genotypic (GCV) coefficients of variation were recorded in case of tiller per plant (PCV=16.37%, GCV=9.14%). High estimates of broad sense heritability (> 75%) were recorded for plant height (80.00%) and Tiller/plant, in sodic soil showed moderate estimate of genetic advance in percent of mean (10-20%). High heritability and genetic advance indicate that the additive nature of gene action and reliability of those characters for selection and emerged as ideal traits for improvement through selection.
