Abstract:
An experiment was conducted at Agronomy Farm, S. K. N. College of Agriculture, Jobner (Rajasthan) during Kharif, 2015 for screening of 11 genotypes of green gram [Vigna radiata (L.) Wilezek] against white fly (Bemisia tabaci), jassid (Empoasca kerri). The initiation of jassid and whitefly population recorded in the first week of August (32 SMW) which reached its peak in first week of September, i.e. 36th SMW (12.90 jassid and 14.20 whitefly/ three leaves) when maximum temperature, minimum temperature and relative humidity was 36.1 and 21.70C and 90 per cent, respectively and gradually decline thereafter. Out of eleven genotypes of green gram screened for relative resistance against white fly (Bemisia tabaci), jassid (Empoasca kerri). Genotypes, RMG-344, RMG-1051 were categorized as highly resistance, RMG-1079, RMG-975, MUN-2, RMG-1010, MSG-118 and RMG-1076 as moderately resistance, followed by RMG-492, RMG-268 and RMG-62 as less resistance.
