Path analysis study and morphological characterization of sweet pepper (Capsicum annuum L. var. grossum.)

Abstract

The present study was conducted with seven diverse inbred lines of sweet pepper& five hybrids at Central Research Farm, Gayeshpur, B.C.K.V., Nadia, West Bengal during autumn-winter season of 2017-18 to find out the direct & indirect effects of seventeen important quantitative traits on fruit yield of sweet pepper. The study revealed that fruit length (0.9839) had maximum positive direct effect on fruit yield followed by reducing sugar content (0.6591), fruit weight (0.5129). On the other hand maximum negative direct effect on fruit yield per plant was showed by chlorophyll content at mature green stage (-0.0104) followed by ascorbic acid content at mature green stage (-0.0270), beta carotene content at coloured stage (-0.0342). Parental genotypes & hybrids are also characterized based on some qualitative characters like leaf shape, leaf colour, fruit orientation, flower colour, fruit shape, immature, mature and fully ripe fruit colour. Variability regarding these traits exists among the inbreds and hybrids under study.
