Abstract

Sweet potato [Ipomoea batatas (L.) Lam.] is one of the important tuber crops of tropical and sub-tropical regionsof the world. Studies on mean performances of 51 sweet potato genotypes was carried out at Shalmala Vegetable ResearchCentre, Regional Horticultural Research and Extension Centre (RHREC), Dharwad (University of Horticultural Sciences,Bagalkot) during rabi, 2019-20 and 2020-21. The evaluation study indicated that sufficient amount of variation existedamong the genotypes for growth and yield. Among the sweet potato genotypes, maximum tuber length was recorded inBSP-39 (18.11 cm), tuber diameter in NBS-4 (9.35 cm), mean weight of tuber in BSP-28 (269.85 g), for number of tubersper vine (5.45), tuber yield per vine (859.69 g), tuber yield per plot (42.98 kg) and tuber yield per hectare (47.76 t) wasnoticed in BSP-1 genotype. Significant variation in growth and yield parameters among different genotypes of sweet potatomay be due to the inherent genetic makeup of the genotype and influence of environmental conditions.
