Abstract

Sweet potato [Ipomoea batatas (L.) Lam.] is one of the important tuber crops of tropical and sub-tropical regions of the world. Studies on mean performances of 51 sweet potato genotypes were carried out at Vegetable Research Centre, Regional Horticultural Research and Extension Centre (RHREC), Dharwad  during rabi, 2019-20 and 2020-21. The data was  collected on 20 characters. High estimates of PCV, GCV, heritability and high genetic advance as per cent of mean were recorded for tuber yield per vine, the number of leaves per vine, the mean weight of tuber per vine, vine length and tuber yield per hectare.

Keywords: Sweet potato, genetic variability, genetic advance, heritability
