dc.description.abstractTwenty-one genotypes of potato were carried out in Randomized Block Design with three replications during Rabi season 2020-21 at Horticulture Research Center of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.). Eleven characters were included in the present investigation to study the variability, heritability, and genetic advance in potato. The analysis of variance was recorded highly significant difference between the genotypes for all eleven traits under studies. The estimates the coefficient of variation relieved that magnitude of phenotypic coefficient of variation was higher than genotypic coefficient of variation for all the characters. High estimates of phenotypic as well as genotypic coefficient of variation were observed in case of length of internodes (cm), followed by plant height, tuber yield plant-1, number of stem plant-1, number of nodes at 30 DAP, number of tubers plant-1. Heritability estimates, as well as genetic progression, were found to be more important than heritability in predicting the outcome of selecting the best individual. High estimates of heritability (h2) (>80%) were recorded for tuber yield plant-1, followed by number of leaves at 60 DAP, number of nodes at 60 DAP, plant height (cm), number of nodes at 30 DAP, tuber size (cm), length of internodes (cm), number of tubers plant-1, number of stem plant-1, number of leaves at 30 DAP. The highest value of genetic advance in percent of mean (>20%) was exhibited for length of internodes (cm), plant height, tuber yield plant-1, number of stem plant-1, number of nodes at 30 DAP, number of tubers plant-1, number of leaves at 60 DAP, number of nodes at 60 DAP, tuber size (cm).en_US
