Abstract:

Variability studies provide information on the extent of improvement possible in different characters, but they do not throw light on the extent and nature of relationship existing between yield and various contributory characters. Character association or correlation is a measure of the degree of association between two characters. A knowledge regarding the association of various characters among themselves and with economic characters is necessary for making indirect selection for improvement of economic characters. The gamma radiation induced 190 M4 mutant lines of cluster bean [Cyamopsis tetragonoloba (L.) Taub.] obtained from Centre for Biotechnological Research (CBR), College of Horticulture, Bengaluru were used for the field experimentation at College of Horticulture, Mysore. Such collected 190 M 4 mutants of cluster bean were investigated for various yield and its associated characters. The data was recorded on number of days to 50 per cent flowering, number of days to 50 per cent maturity, number of days to harvest, plant height, number of branches per plant, pod breadth, pod length, number of pods per cluster, number of clusters per plant, number of pods per plant, ten pods weight (g), pod yield per plant (g), seeds per pod, seed yield per plant (g), 100-seed weight (g). Analysis of variance revealed highly significant difference among the mutants for all the characters studied. Correlation revealed highly significant and positive association of vegetable pod yield and other yield component characters. A positive correlation for pod yield with days to 50 per cent maturity, pod length (cm), pod width (cm), days for harvest, pods per cluster, pod clusters per plant, pods per plant, 10 pods weight (g), pod yield per plant (g), seeds per pod, seed yield per plant (g) and 100 seed weight (g). A non-significant but positive correlation was also observed with plant height and number of branches per plant.
