abstract
Investigations on “Varietal screening of chilli against major sucking insect pests” were conducted at Horticulture farm and Department of Entomology, S.K.N. College of Agriculture, Jobner during Zaid, 2014 and 2015. Out of ten varieties of chilli screened against major sucking insect pests, none was found completely free from the attack of pests. The varieties, Pant C-1, Mathania Local and Alakhpura Selection were ranked as least susceptible, while Pusa Jawala and PS-64 as highly susceptible and Moti Hira-31, Selection-5, MY Selection-71, Dhan Laxmi-21 and RCH-1 as moderately susceptible. The biochemical characters of these varieties viz., free amino acid and total soluble sugar content had positive correlation whereas, total phenol had negative correlation with the population of thrips, whitefly and per cent leaf curling. The maximum fruit yield of chilli was also obtained in the variety Pant C-1, followed by Mathania Local and Alakhpura Selection and minimum was in Pusa Jawala and PS-64.
