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, path coefficient analysis and genetic diversity.
Each genotype was grown in a single row of 5.0 m length with a spacing of 30 × 10
cm, inter row and intra row, respectively. Observations were recorded on five
randomly selected plants for the characters viz., plant height at 50 % flowering (cm),
tillers per plant, leaves per plant, leaf length (cm), leaf width (cm), stem thickness
(cm), leaf: stem ratio, green forage yield per plant (g), dry matter content (%), dry
matter yield per plant (g), crude protein content (%), crude protein yield per plant (g),
neutral detergent fibre content (%) and acid detergent fibre content (%), whereas, days
to 50 per cent flowering was recorded on plot basis.
