Abstract:
The present investigation on “Screening of Sweet Potato, Ipomoea batatas (L.) Germplasm for preference/ non preference by sweet potato weevil, Cylas formicarius (Fabricius)” was carried out at Horticulture Farm, Rajasthan College of Agriculture, MPUAT, Udaipur during Kharif, 2021. Eight germplasm of Ipomea batatas (S.T.-14, Local, TSP-16-10, TSP-16-9, TSP-16-7, TSP-16-6, TSP-16-5, TSP-16-3) were evaluated for studying their relative susceptibility against Cylas formicarius. The result revealed that the vine infestation and tuber infestation were minimum in germplasm TSP-16-7 which recorded the highest marketable tuber yield of 24.86 t ha^-1. Whereas vine infestation and tuber infestation were maximum in germplasm ST-14 which recorded a marketable tuber yield of 13.82 t ha^-1. The germplasm are arranged in decreasing order with respect to mean per cent vine infestation and tuber infestation: ST-14 >Local > TSP-16-5 > TSP-16-9 > TSP-16-6 > TSP-16-3 > TSP-16-10 > TSP-16-7.
