Résumé
In the present investigation, the objective of the research is to identify suitable parents and desirable hybrid combinations using Line x Tester mating design. The experimental material comprised of 50 pearl millet hybrids generated by 10 female lines crossed with 5 male testers in Line x Tester fashion. These 50 pearl millet hybrids along with three standard check hybrids were evaluated in randomized block design with three replications during kharif, 2014 at Agriculture Research Station, Bikaner. Analysis of variance exhibited significant differences among the hybrids for all the studied ten characters indicating presence of good amount of variability. Among all the characters, high GCV and PCV were observed for biological yield per plant (g) and seed yield per plant (g) in comparison to other characters indicating the presence of high amount of genetic variability for these characters. High heritability along with high GCV were recorded for biological yield per plant. While test weight and biological yield per plant also had high heritability associated with high genetic advance as per cent of mean. Plant height, ear head length and test weight had high estimate of GCV, PCV and moderate to high heritability Therefore, selection for these characters would be effective.
