Genetic variability, heritability and correlation studies of various quantitative traits of mungbean (Vigna radiate L.) at different radiation levels


Hafiz Muhammad Ahmad, Muhammad Ahsan, *Qurban Ali and Imran Javed

The experiment was conducted in the research area of the Department of Plant Breeding and Genetics, University of Agriculture Faisalabad, during spring season 2010. The experimental material was comprised of four irradiated mungbean genotypes as AUM-18, AUM-19, AUM-3 and Mung 2004. From the experiment it was concluded that maximum emergence rate was observed by AUM-31 at the level D2 followed by the genotype AUM-18 which gave the maximum yield at dose level D1. AUM-19 produced maximum plant height at first pod maturity followed by AUM- 18, while regarding dose level maximum plant height was produced at the level D1. Maximum plant height at 90% pod maturity was obtained by genotype AUM-19 at D1, AUM-19 at level D2 and AUM-18 at dose level D3. AUM-31 produced maximum clusters per plant at D1 and D2 and D3 levels and Mung-2004 gave the minimum cluster per plant at D2 and D3. AUM-19 produced maximum pods per plant at all three levels while it remained minimum regarding the genotype AUM-31 at all three levels. AUM-31 produced maximum seeds per pod at D1, D2 and D3 levels. AUM-18 showed no effects for seed per pod on all dose levels. Maximum seed yield per plant was produced by AUM-18 at dose level D1 while it was observed minimum for AUM-19 at D3. The phenotypic correlation for emergence rate with plant height at first pod maturity, plant height at 90% pod maturity, pods per plant, Grains per pod was negative and non significant while it was positive with cluster per plant and 100-seed weight. It was suggested that the selection of higher yielding mungbean genotypes may be helpful on the basis of induced mutations and Germplasm may be used for mutation breeding programme.
