Heritability and genetic advance estimate of seed yield, yield attributes and different biochemical parameters from parents, F1 hybrids and segregating generations of pearl millet [Pennisetum glaucum (L.) R. Br.]

Abstract

The present investigation pertaining to study of narrow sense heritability and genetic advance for yield, yield attributes and biochemical parameters in ten morphologically diverse parents were taken to produce F1 hybrids and its subsequent segregating generations. The F1 hybrids were developed at Center for Crop Improvement, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat during kharif 2020 and subsequently F1 hybrids along with their both the respective parents were sown in Summer 2021 to produce seed for F2, BC1 and BC2 generations. All six populations were evaluated during kharif 2021 at same location. Analysis of variance indicated that some crosses showing significant differences that suggested the presence of sufficient variation of crosses for different traits there by revealing existence of sufficient variation to analyze and interpret the results in terms of objectives under investigation. Low, medium and high estimates of narrow sense heritability and genetic advance were found in different plant characters under the study. Cross 98222 B × 15550 R and 05888 B × 16066 R of grain yield per plant and some other crosses of yield attributes and biochemical characters also depicted high narrow sense heritability along with high genetic advance, so it indicated higher additive gene action and lower environmental factors in the expression of these traits with possibility of improvement through selection.
