Abstract: The present investigation was conducted during growing season of 2017-18. Data collected on tuber yield and its components were subjected for analysis of variability parameters, correlation coefficient and genetic advance. The estimates of analysis of variance were significant for the all parameters.The analysis of genetic variance revealed that the sufficient variability was present in experimental material. The Phenotypic coefficient of variation (PCV) was slightly higher in magnitude than genotypic coefficient of variation (GCV) for all the parameters. The high heritability estimates in broad sense was recorded in weight of ‘C’ grade tubers per hill, number of stems per hill, yield of tubers per hill (kg plant-1), number of leaves per plant, weight of ‘A’ grade tubers per hill, weight of ‘B’ grade tubers per hill, number of ‘C’ grade tubers per hill, weight of ‘D’ grade tubers per hill. The high heritability estimates coupled with high genetic advance was recorded for the parameters number of ‘D’ grade tubers per hill, weight of ‘D’ grade tubers per hill, weight of ‘C’ grade tubers per hill, number of ‘B’ grade tubers per hill, weight of ‘B’ grade tubers per hill and yield of tubers per hill (kg plot-1).
