Abstract

An experiment on Physical plant characters of cauliflower and their correlation with Pieris brassicae L. (Lepidoptera: Pieridae) was studied on ten cauliflower genotypes i.e, Snow mystique, White magic, Sydney, White corona, Local, Snow grece, Clima, 5340, Snow crown and AX-2034. The study was done under field condition at Entomology section ARI Tarnab Peshawar. During 2012-13 maximum plant height and leaf length was recorded on White Magic (63.5 cm) and (54.86 cm) respectively. No significant difference in leaf area and Leaf thickness was recorded among the ten cauliflower genotypes. The leaf area ranged from 434.3 cm (White Corona) to 1370.5 cm (Snow Grece) and leaf thickness ranged from 0.3825 mm( AX-2034) to 0.4975 mm(White Corona).During 2013-14 maximum plant height and leaf length was observed on White Magic i.e (69.4 cm) and (64.4 cm) respectively. Leaf area was non-significantly different among the 10 genotypes, where it ranged from 536.17 cm (Sydney) to 1097.08 cm (White Magic). Leaf thickness was significantly higher of Sydney (0.485 mm) while lower in each of Clima and 5340 (0.347 mm). P. brassicae egg, larval density and yield of cauliflower were
