Physico-morphic factors imparting resistance in different Brinjal cultivars against sucking insect pest of Brinjal

Tayyib Ahmad, Khadija Javed, Kashif Hussain, Ajmal Khan Kassi and Humayun Javed

Response of different brinjal cultivars against sucking pest like aphid, jassids, whitefly and thrip’s was evaluated at research farm Arid Agriculture University, Rawalpindi, during 2013. The data regarding the sucking pest population revealed that Round Brinjal 86602 was the comparatively resistant cultivar with 0.136 nymphs, 0.049 adult, 0.073 adult and 0.060 adults per leaf respectively. Yield mean data shows that the Round Brinjal 86602 was the highest yielding among all the tested cultivars with the yield of 1.15 kg/plant which was highly significant. According to the physico-morphic characters number of hairs on fruit crown and hairs on leaf midrib were 14.49 and 71.49 hairs per cm2. Correlation between sucking pest and abiotic factors the minimum, maximum and average temperature has a negative correlation with the aphid infestation on all the cultivars except Short purple with 0.058. Rainfall during the growing season has a positive correlation with the aphid infestation. The average temperature has negative correlation with jassid population on Round brinjal 86602, Round White Brinjal and singhnath 666 with -0.006, -0.058 and -0.541. Based on the sucking pest population, physic-morphic characters and correlation with abiotic factors the Round Brinjal 86602 proved to be comparatively resistant and Short Purpal is susceptible cultivar.
