ABSTRACT
An experimental study was conducted to screened out the different resistant varieties of cotton against thrips, Thrips tabaci.In this experiment seven cotton genotypes viz. MNH-886, MNH-986, MNH-554, MNH-52, NIAB-78, NIAB-98 and NIAB-999 were sown on dibbling method during 2017. The present study resulted that no variety was free from the attack of thrips population. Among all tested varieties, NIAB-78 and MNH-886 were found most resistant and susceptible against thrips, respectively. The mean population of thrips on MNH-886 and NIAB-78 were recorded 5.43 and 3.49 per plant, respectively. The study revealed that NIAB-98 (4.92/plant) and NIAB-999 (4.92/plant) were found more attractive varieties against thrips population during the whole study period. The study concluded that NIAB-78 is best variety and shows resistance against insect pests like thrips.
