Genetic variability study in sweet potato (<i>Ipomoea batatas</i> L.) genotypes [link]Paper  abstract   bibtex   
The investigation on genetic variability study in sweet potato was undertaken during the year 2010-11 at Horticulture Research Station RHREC Kumbapur farm, Dharwad, Karnataka. All 52 genotypes showed significant differences for all the characters studied. GCV and PCV were low to high for all characters. High heritability with high GAM was recorded for vine length, leaf area index, number of tubers per vine, total soluble solids, tuber length, tuber yield per plot and tuber yield per hectare which indicates the presence of additive gene effects for these traits. Hence improvement can be done through phenotypic selection. High heritability with low to moderate GAM was observed for inter nodal length, number of auxiliary branches and tuber girth which indicates the role of non additive gene effects. Hence, improvement in these traits would be more effective by selecting specific combinations followed by intense matting of lines.
