Genetic analysis using Griffing’s approach for forage yield and components in sorghum

The present study was carried out using seven parental lines including check CSV 46F and their 21 diallel crosses, excluding reciprocal. experiment evaluated in randomised block design with three replications during Kharif 2021 at the Centre for Millets Research, Sardarkrushinagar Dantiwada Agricultural University, Deesa. analysis of variance (mean sum squares) revealed significant differences genotypes, parents, hybrids parents vs. among most characters, which explained a sufficient amount heterosis reflected crosses fodder yield its attributing characters. SH 1488 DS 200 recorded maximum mean performance green forage dry per plant. result ANOVA combining ability that squares due to GCA SCA were found highly studied ratio ( 2GCA/ 2SCA) variances various characters bare standing non-additive gene action type appearance supporting parent 21F be good general combiner While, 1488, combiners yield.

Based on all genetic parameters, DSF 182 high performance, effects least one having moderate gca would increase frequency favourable alleles. Therefore, it may hopeful select homozygous ameliorate respective sorghum. It can also used directly varietal breeding programmes. Keywords: Forage sorghum, Heterosis, GCA,
