Sweet potato [Ipomoea batatas (L.) Lam.] is one of the world’s highest-yielding crops and is widely grown as a stable food in many tropical and subtropical regions. It is a dicotyledonous plant belonging to the family Convolvulaceae (also called morning glory family). It originated from South America. Sweet potatoes are thought to be naturally hexaploidy, with a chromosome number of 2n(6x) =90, making them a highly heterozygous crop. Research was conducted in a randomized block design with three replications during rabi 2023-24 at Main Vegetable Research Station of Anand Agricultural University in Anand. Analysis of variance revealed that highly significant differences among the genotypes were observed for all the characters under study. The PCV was higher than GCV for all the characters. High (> 20 %) genotypic coefficient of variation (GCV) and phenotypic coefficient variation (PCV) were observed for all the characters studied except tuber moisture content, which indicates the existence of broad genetic base and it would be useful for further selection. High heritability (> 60 %) coupled with high genetic advance as per cent over mean (> 20 %) were recorded for all the characters studied indicated the prevalence of additive gene action for these traits. Thus, there is ample scope for improving these characters through direct selection in crop improvement programme

Sweet Potato, Genotypes, Variability, Heritability, Genotypic coefficient of variation, Phenotypic coefficient of variation

In conclusion, analysis of variance showed the presence of highly significant differences among the tested genotypes for the characters considered which indicates the existence of notable genetic variability among the genotypes for all the characters studied viz., vine length, internode length, petiole length, tuber girth, tuber length, total number of tubers per plot, tuber yield per plot, harvest index, total soluble sugar, starch content, tuber moisture content, β-carotene, reducing sugar and non-reducing sugar indicates the presence of sufficient amount of variability in all the characters under study
