Abstract:
The present study was conducted under AICRP-Potato at the Research cum Demonstrational Farm, Department of Vegetable Science, College of Agriculture, IGKV, Raipur (C.G.) during Rabi season of 2020-21. The experiment, consisting of 09 genotypes of potato was laid under Randomized Complete Block Design (RBD) with three replications. Data collected on tuber yields and its components was studied for Genetic variability, heritability and advance in 75 DAP. The analysis of variance revealed that mean sum of squares was significant for most of the characters except dry weight of tuber plant-1 (0.710) and fresh weight of shoots plant-1 (1352.630). The heritability estimates in broad sense was recorded high for the characters viz., plant emergence percentage (87.0 per cent), seed weight t ha-1 (82.9 per cent), tuber girth (80.5 per cent), harvest index percentage (77.3 per cent) and fresh weight of tubers plant-1 (70.4 per cent. The moderate genetic advance was obtained for characters namely, fresh weight of tubers plant-1 (28.69 per cent), process grade tuber yield t ha-1 (28.22 per cent) and number of tubers plant-1 (25.35 per cent). The presence of moderate genetic advance suggests that both the additive and non-additive variance is operating in these traits.
