Abstract: The investigation was conducted at AICRP on Tuber Crops, Regional Horticultural Research Station, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari, during Rabi 2017-18 with forty four sweet potato genotypes. This was to study genetic variability, heritability and genetic advance as per cent mean for several economic characters to identify promising cultivars suitable for the South Gujrat conditions. Data collected on eighteen characters exhibited significant differences among genotypes in respect of all the characters studied. Phenotypic coefficient of variation (PCV) was higher than Genotypic coefficient of variation (GCV) for all the traits, indicated a low environmental influence on expression of these traits. High heritability coupled with high genetic advance as per cent mean was observed yield per plot followed by β-carotene, non-reducing sugars, yield per plant, leaf area, vine length, petiole length, number of tubers per plant, number of branches per plant, ash content, tuber girth, internode length, total sugars, reducing sugars, tuber girth, starch except moisture content under study indicated that the characters are controlled by additive gene action and selection would be effective. These characters-with high GCV, PCV, heritability and genetic advance as per cent mean-should be considered as reliable selection criteria for crop improvement for yield and yield attributing characters.
