Genetic variability and traits association among mungbean (Vigna radiate) genotypes under rainfed condition

摘要

Development of superior cultivars is the prime objective of any plant breeding program. This research was conducted with the aim to study genetic variability and trait association among the mungbean genotypes for yield attributes under rainfed conditions. Fourteen mungbean genotypes were tested in randomized complete block design with three replications at the University of Agriculture Peshawar during spring 2017. Data were noted on different yield contributing traits like days to maturity, plant height, pods plantSUP-1/SUP, pod length, clusters plantSUP-1/SUP, 100-grain weight and grain yield plantSUP-1/SUP. Analysis of variance revealed highly significant difference for all the studied traits. Maximum number of clusters plantSUP-1/SUP were showed by genotypes Mung-Azri-06 (9) VC 6321(9), Mung NM-06 (9) and Mung-Chakwal-06 (9). Mung-Azri-06 revealed maximum pod length (8.6 cm), pods plantSUP-1/SUP (27.37), 100-grain weight 4.40 g) and grain yield (17.90 g). Grain yield showed significant correlation with cluster plantSUP-1/SUP(r = 0.71**), pods plantSUP-1/SUP (r = 0.80**), pod length (r = 0.59*) and 100-grain weight (r = 0.97**). Promising genotypes Mung-Azri-06, Mung-Chakwal-06 and Mung- NCM-257-2 performed best than other genotypes and can be used in future breeding programs.
