Screening of Mungbean (Vigna radiata L. Wilckzek) genotypes for resistance against whitefly (Bemisia tabaci Gennadius) under natural infestation conditions

Abstract

Thirty three Mungbean genotypes were evaluated for resistance against whitefly (Bemisia tabaci) during kharif 2018 under natural infestation conditions. Whitefly adult population ranged from 2.00 (MH 1772) to 17.22 adults/leaf (MH 1315) and 3.33 adults/leaf (MH 1142) to 14.56 adults/leaf (MH 1431) at 35 and 45 days after sowing, respectively. Maximum and minimum populations of whitefly adults were recorded at 35 days after sowing of the crop. On the basis of overall mean (35 and 45 Days after sowing) of whitefly adult population, genotypes, MH 1489, MH 1468, MH 1457, MH 1762, MH 1718, MH 1720, MH 1722, MH 1750, MH 1754, MH 1772, MH 1142, MH 1344, MH 1346 and MH 42 found promising having less than 6.0 whitefly adults/leaf.
