Abstract

An evaluation of 84 accessions of pearl millet {Pennisetum glaucum (L.) R. Br.} germplasm for green fodder yield over one season revealed highly significant differences among accessions for days to heading, plant height, tillers per plant, leaves per plant, leaf area, leaf to stem ratio, stem diameter, green fodder yield per plant, dry fodder yield per plant and green fodder yield per plot. The genotypic and phenotypic coefficient of variation were more or less similar for all the characters. Broad sense heritability was moderate 54.89% for tillers per plant to high {69.89% for green fodder yield per plot (kg)} confirming that genotypic variance has contributed substantially to the total variance. Based upon character association and path analysis, it may be concluded that tillers per plant was the major yield component, because it has high positive significant association and positive direct effect on green fodder yield. Based on mean performance of the accession IP-3613, IP-17423, IP-14450, IP-3585 and IP-17394 were observed superior due to high mean value of tillers per plant, leaves per plant and earliness in flowering. Therefore, these accession should be utilized in further breeding programme for developing superior varieties.
