Abstract

Field screening of 51 sweet potato genotype against sweet potato weevil was conducted at AICRP on tuber crop, Vegetable Research Centre, Regional Horticultural Research and Extension Centre (RHREC), Dharwad during rabi, 2019-20 and 2020-21 (two seasons) The treatments in each replication were allotted randomly by using random number table. Sweet potato cuttings which have 2-3 buds were planted in each replication with 3 m × 3 m plot size at 60 cm × 20 cm spacing. The crop was raised by following the recommended package of practices of University of Horticultural Sciences, Bagalkot. The lowest weevil incident were observed in the 5 sweet potato genotypes, among these genotypes four genotypes viz., BSP-1, BSP-26, BSP-27, BSP-32 are good yield compare to check (Sree Bhadra) these four genotypes are considered for future research work and for commercial cultivation.
