SELECTION OF TRAITS FOR YIELD IMPROVEMENT IN CHILLI (Capsicum annuum L.) (Pages : 78 - 87)

The experiment was conducted at R & D Farm, Lal Teer Seeds Limited, Gazipur, Bangladesh. At Phenotypic level, yield per plant was significantly and positively correlated with fruit length, fruit weight and number of fruits per plant and days to fruit maturity (green). At Genotypic level, yield per plant significantly and positively correlated with all the characters mentioned above including fruit width. Significant and positive correlation was existed between plant height and plant canopy width at genotypic level. Fruit length had significant and positive genotypic and phenotypic correlation with fruit width and fruit weight. Multicolinearity between the traits was minumum. Number of fruits per plant was positively and significantly correlated with yield per plant (0.519) at phenotypic level. The direct effect of number of fruits per plant (0.653) was very close to correlation value and five different characters were involved to indirect positive effect. At genotypic level, the direct effect (0.501) was closer to correlation value (0.542) and indirect positive effect was acting through seven different characters. Selection should be done through number of fruits per plant. The residual effect of path analysis was 0.21 at genotypic level indicated all the important traits had been considered.Download
