Abstract

An experiment comprised of fifty diverse accessions of forage [Pennisetum glaucum (L.) R. Br.] was conducted in randomized complete block design with three replications during Kharif -2020 at Main Forage Research Station, Anand Agricultural University, Anand to study the genetic variability, heritability, genetic advance, characters association and path coefficient analysis. The magnitude of phenotypic coefficient of variation was observed higher than corresponding genotypic coefficient of variation for all the characters under study. High genotypic and phenotypic coefficient of variations were observed for crude protein yield per plant, green forage yield per plant and dry matter yield per plant, which indicated the presence of sufficient amount of variability for these traits. High heritability coupled with high genetic advance for green forage yield per plant, plant height, stem thickness, leaf width and number of leaves per plant indicated good response of selection. Plant height, leaf length, leaf width, stem thickness, dry matter yield per plant, crude protein yield per plant and neutral detergent fiber content showed positive and significant correlation with green forage yield per plant and its quality at both genotypic and phonotypic levels. Path analysis indicated dry matter yield per plant, crude protein yield per plant, number of tillers per plant and stem thickness exerted a strong positive direct effect on green forage yield per plant.

Conclusion

From the present investigation, it can be concluded that due weightage should be given to plant height, leaf length, leaf width, stem thickness, number of tillers per plant, dry matter yield per plant, crude protein yield per plant and neutral detergent fibre content while imposing selection for genetic improvement of green forage yield per plant in forage bajra. On the basis of per se performance the genotypes viz., Giant Bajra, GP 138, AFB 3, ICMV 1611, 743 KH 16, ICMV 1701, ICMV 1608, ICMV 1616 can be further utilized in the future breeding programme for the development of high yielding varieties/ hybrids in forage bajra.
