An investigation on correction and path analysis in redgram was carried to elicit the information on nature and extent of the genetic variability, heritability, genetic advance, character association and path analysis. Observations were recorded on thirteen characters. The analysis of variance indicated significant difference among the genotypes for all the 13 characters studied. The genotypic coefficient of variation for all the characters studied were lesser than the phenotypic coefficient of variation indicating masking effects of the environment. Character association studies and Path coefficient analysis revealed significant and positive correlation of seed yield per plant with number of secondary branches per plant, number of pods per plant, dry matter content per plant and harvest index and simultaneous improvement of these characters along with seed yield is possible.

Among the fodder crops, Forage Sorghum has a critical role because its characteristics are suitable for the climate of Pakistan. Breeding programmes involving the selection of better accessions depend upon the available and potential variability in the genetic makeup. However, when the information on genetic correlation among green fodder yield and its components is available, the crucial task of screening the genetic material becomes easy. The present studies were undertaken to evolve an efficient selection benchmark to facilitate the future potential breeding programmes and to select the lines on the basis of possession of traits having high contribution to yield.
