Abstract

The genetic characteristics for eight quantitative traits were studied using a set of 40 pearl millets genotypes. Peral millets is the only crop which is enriched with nutrients and can give robust yield under harsh conditions. Therefore, exploring the variability, heritability and other parameters can make it as potential crop for future. Analysis of variance revealed significant differences for all studied parameters in the experimental materials. All characters have a high broad sense heritability. Except for days to maturity, all traits had the highest heritability when combined with GAM. GCV values were highest for productive tillers/plant and fodder yield/plot. Plant height, productive tillers per plant, yield per plant, and fodder yield per plot all had the highest PCV. At both the genotypic and phenotypic levels, grain yield per plant demonstrated a strong significant positive association with attributes such as fodder yield per plot, productive tillers per plant, panicle lengt

Conclusion

Variability most important for breeding potent varieties, by ANOVA we came to know there is significant amount variation present with the population for all studied parameters. All characters have a high broad sense heritability. Except for days to maturity, all traits had the highest heritability when combined with GAM this means selection of these characters is worthy in improving the yield ability of genotypes. PCV observed little bit high than GCV values showing environmental influence on the characters. Plant height, productive tillers per plant, yield per plant, and fodder yield per plot all had the highest PCV showing genotype and environmental interaction on character expression. At both the genotypic and phenotypic levels, grain yield per plant demonstrated a strong significant positive association with attributes such as fodder yield per plot, productive tillers per plant, panicle length, and panicle diameter showing true relationships with grain yield per plant, according to
