Combining ability studies for yield and yield contributing traits in Mungbean (Vigna radiata (L.) Wilczek)

Abstract

The present study on was conducted during Kharif 2017. Combining ability in respect of following characters viz., days to 50% flowering, days to maturity, plant height (cm), number of clusters per plant, number of pods per cluster, number of pods per plant, number of seeds per pod, 100 seed weight (g), pod length (cm), seed yield per plant (g) and protein per cent, involving four lines and five testers and their 20 hybrid combinations with one standard check. The experiment comprised of four female and five male parents and their 20 F1s hybrid was conducted in randomized block design with two replications. Mean data of genotypes was analyzed as per line x tester mating design while mean data of 30 genotypes (including check and promising hybrids) was used for the estimation of combining ability. The parents showed high GCA can be used for the future hybridization programmes. The GCA estimates of lines and testers emphasized the importance of lines BPMR 145 and tester SML 832, BWUC 10.1.1.21.1 for their use as a desirable parents for enhancing the yield potential through assembling the favourable genes for yield and yield components. The crosses which showed high SCA effect could be used for the hybrid development. The crosses BM 4 x BWUC 8-1-1 found to be the superior for cluster per plant and number of pods per plant. Should be further tested across the different environment for their stability performance.
