Screening of mungbean (Vigna radiata (L.) wilczek) genotypes against sucking insect pests under natural field conditions

This study was conducted to examine the resistance in eight advance mungbean genotypes in comparison with two check varieties against sucking insect pests under natural field conditions at nuclear institute for agriculture and biology (niab),faisalabad. findings of the trial showed that none of the tested genotypes have complete resistance against sucking pests i.e.,whiteflies,thrips and jassids. comparison of resistance among the tested genotypes against whitefly showed that the lowest number of whiteflies per leaf (3.7±1.20) was observed in mh 3153,lower than those of both checks,whereas,the highest (11±1.53) was observed in mh 34143. number of thrips per leaf was observed the lowest (4±1.00) and the highest (12.3±0.67) in cultivar mh 3153 and mh 34143,respectively. similar population trend of jassid was observed with per leaf population of 1.2 and 3.3,the highest and the lowest in mh 3153 and azri 2006,respectively. among all the tested cultivars,mh 3153 gave the highest yield (438.7 g/plot) with 129 and 161% increase over check 1 and check 2,respectively. therefore,genotypes which showed the highest resistance against the sucking pests and tied with high grain yield could be used for direct release as variety or may be used in cross breeding programme to get improved resistant germplasm against sucking insects. copyright © 2014 zoological society of pakistan.
