| dc.description.abstract | The study on spectral variability for horticultural traits and spikelet sterility in induced mutant population of cluster bean [Cyamopsis tetragonoloba (L.) Taub.] revealed significant variation for morphological and horticultural traits. The 190 M4 mutant line of cluster bean obtained from Dept. of BCI, COH, Bengaluru. The ANOVA for all the mutants from field study revealed significant variation for all the characters except for days to 50 per cent flowering. The genotypic coefficient of variation was higher than phenotypic coefficient of variation for all the characters studied. Genotypic coefficient of variation ranged from 18.46 (days for 50 per cent flowering) to 49.17 (pod yield per plant). Phenotypic coefficient of variation ranged from 18.16 (days for 50 per cent flowering) to 49.05 (pod yield per plant). The estimates of heritability ranged from 62.70 per cent (branches per plant) to 99.60 per cent (pods per cluster and clusters/plant). Genetic advance expressed as percentage over mean ranged from 36.74 per cent (days for 50 per cent flowering) to 99.10 per cent (pod yield per plant). Correlation studies revealed highly significant and positive association of vegetable pod yield per plant, which exhibited significant and positive correlation for all the characters but it is positively and non-significantly correlated with plant height and number of branches per plant. Among all the mutants studied the superior mutants obtained are C84 (368.72 g) is having highest yield/plant, C114 (29.16 g) is having highest seed yield/plant and 100-seed weight was observed highest in the mutant E 179 (7.92 g). The following are the 12 superior male sterile mutants observed in the present study A5, A16, A23, B52, B60, B61, C93, C94, C102, D124, D136 and D141 and the sterility was confirmed by acetocarmine smear test. These sterile lines shall be further advanced and utilized in the hybrid development. | en_US |
