Genetic Analysis of Some Quantitative Traits in Cluster Bean (Cyamopsis tetragonoloba L.)

An experiment comprising of eight promising genotypes of cluster bean developed at Agricultural Research Station, Bahawalpur, Pakistan was conducted to study the genetic differences among the genotypes during Kharif season, 2014. The experiment was laid out in RCBD and data on five characters i.e. grain yield (kg ha-1), plant height (cm), number of branches plant-1, number of pods plant-1 and number of grains pod-1 were recorded. Analysis of variance showed highly significant differences among all the genotypes. A significant level of correlation was also noticed among quantitative traits. Number of branches plant-1 were negatively correlated with all characters while grain yield, plant height, number of pods plant-1 and number of grains pod-1 were positively correlated with each. The genotype S-5498 was found to be higher yielder which produced grain yield of 2093kg ha-1 followed by S-5488 which produced 2037 kg ha-1 respectively as compared to standard variety BR-99 (1533 kg ha-1).While the genotypes S-5490 and S-5497 were the lowest yielders and yielded grain yield of 993 kg ha-1 each.
