Abstract
Rapid change in the environment due to global warming is not only linked with the scarcity of food but with the availability of green fodder also. Thirty mungbean genotypes were evaluated using randomized complete block design for fodder yield across years at two extreme environments of Pakistan; badly affecting by the flood. Broad-sense heritability and selection response were studied for degree of indeterminacy, petiole length, fresh and dry biomass. Significant differences at (P≥0.01) were spotted out among the genotypes at both locations for the parameters under study. All the genotypes responded differently for petiole length, fresh and dry biomass in selected years except degree of indeterminacy that did not affected by the weather change in a particular environment. Of the first order interactions (L×Y, G×L), variation was observed for degree of indeterminacy while; dry biomass was highly significant only for G×L and G×Y. However, G×L×Y was absolutely non-significant for parameters studied. The parameters studied for fodder purpose were greatly influenced by the two environments. Means for degree of indeterminacy, petiole length, fresh and dry biomass were 43.1 compared to 20.8
