Abstract:
Bauhinia variegata L. belongs to family ‘Fabaceae’ and sub family Caesalpinioideae and is commonly known as Kachnar. It is one of the important fodder species on which farmer during the winter period rely on. In the present investigation pod and seed parameters were analyzed to determine the relative performance of 25 progenies of Bauhinia variegata. Analysis of variance for different pod and seed characters of important crosses and parents revealed significant variations among full-sibs families. The highest magnitude of PCV was recorded for seed weight per pod (23.85%) and number of seeds per pod (20.13%) whereas the lowest PCV were recorded for seed width (6.65%), seed length (6.69%). The moderate GCV was observed for seed weight per pod (17.69%) while, lowest GCV were found for pod width (4.95%), seed width (5.50%), seed length (5.53%), pod length (6.27%) and number of seeds per pod (9.58%). The highest heritability estimates were observed for seed width (68.38%), seed length (68.32%) and seed weight per pod (55.03%). The moderate genetic advance as percentage of mean was observed for seed weight per pod (27.04%). The high heritability coupled with moderate genetic advance as percentage mean was recorded for seed weight per pod exhibiting additive gene action and selection may be effective in this character. The genotypic and phenotypic correlation showed that all the characters were significant and positively correlated to all other characters at both level. Pod length showed maximum significant and positive correlation with pod width at genotypic levels and pod length showed maximum significant and positive phenotypic correlation with seed weight per pod at phenotypic level.
