Abstract

The 63 hybrids pearl millet (Pennisetum glaucum L.) were evaluated for ten quantitative characters for screening the genetic variability. These hybrids were evaluated in RBD during kharif 2019 conducted at Research Farm of SKRAU, Bikaner Rajasthan Analysis of variance obtained prominent differences among the hybrid varieties for all that characters except days to maturity indicating presence of good variability amount in the hybrids of pearl millet used in the study. As usual the PCV values were found more than GCV values for all traits which indicated positive effect of environment on the characters expression. Biological produce per plant and seed produce per plant had improved estimate of GCV and PCV. Biological produce per plant and seed produce per plant had high estimate heritability along with genetic advance as per cent of mean.

Conclusion

Based on the research findings, it can be conclude that the study shows significant variability among pearl millet hybrids for most traits, except for days to maturity. Replications were non-significant, indicating good homogeneity among replications. The PCV values were higher than the GCV values for all traits, indicating a positive effect of the environment on their expression. The highest GCV values were observed for biological and seed produce per plant, while the highest PCV values were recorded for no. of effective tillers, harvest index, biological produce per plant, and seed produce per plant. Heritability was generally high for ear head length, ear head diameter, harvest index, biological production per plant, and seed produce per plant. Genetic advance was highest for biological produce per plant and lowest for days to 50 percent flowering and days to maturity. The results suggest good variability in pearl millet traits, indicating the potential for selection and breeding programs to improve yield and quality.
