Genetic Variability, Heritability and Genetics Advance studies for yield and its Contributing traits in Pearl millet [pennisetum glaucum (L.) R.Br.] hybrids

Abstract

A field investigation was carried out to estimate the genetic variability, heritability and genetic advance in the pearl millet hybrids. The phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) in all the characters. The highest GCV associated with high heritability of with good genetic advance was observed for biological yield per plant followed by harvest index. The lowest variability associated with low heritability and low genetic advance as per cent of mean was observed for plant height. High heritability in association with high genetic advance observed for biological yield per plant and moderate heritability coupled with high genetic advance observed for harvest index. It indicates that most likely the heritable is due to the preponderance of additive gene effects and the potential of selection for these characters to improve yield.
