Screening of soybean germplasm against whitefly, Bemisia tabaci (Genn.)

Abstract

The field screening of soybean germplasm lines against whitefly was conducted with 24 soybean germplasm lines during Kharif 2015 and 2016. The pooled mean of whitefly incidence among different germplasm lines was in the range of 2.54 to 4.30 whiteflies per plant. The highest number of whiteflies per plant was observed on JS 20-71 followed by DS 3101 and DS 3202. The whitefly incidence was minimum on VLS 89, PS 1550 and SL 955. Based on the response of germplasm lines to whiteflies, the germplasm lines were categorized as moderately resistant (UPSM 534, VLS 89, SL 955, PS 1550, MACS 1410, JS 20-34 and Bragg), susceptible (JS 335, SL 983, SL 688, SL 1028, PS 1556, PS 1347, PS 1092, MACS 1370, KDS 753, JS 93-05, DSb 28-3, Dsb 25 and DSb 2302) and highly susceptible (JS 20-71, DS 3102 and DS 3101).
