Abstract:
The present study was conducted at Research cum Demonstrational Farm, College of Agriculture, IGKV, Raipur (C.G.) during Rabi season of 2020-21. The experiment consisting of ten hybrids of potato was laid under Randomized Block Design (RBD) with three replications. The analysis of genetic variance revealed that the sufficient variability were present in experimental material. The phenotypic coefficient of variance (PCV) was slightly higher in magnitude than genetic coefficient of variance (GCV) for all the parameters revealing influence of environment in expression. The heritability estimates recorded to be high for the characters viz. number of leaves plant-1, seed weight plot-1, plant height, number of shoots plant-1, total tuber yield ha-1 and marketable tuber yield ha-1. The moderate genetic advance was recorded for the characters namely marketable tuber yield ha-1, number of tubers plant-1, total tuber yield ha-1, plant height and number of leaves plant-1 revealed that both the additive and non-additive variance are operating in these traits.
