Abstract

Powdery mildew of chilli caused by Leveillula taurica (Lev.) Arn. is a major constraint for chilli production in many chilli growing states of India. In severely affected plants, defoliation, reduction in photosynthesis and in drastic reduction of fruit yield is often observed. With an aim to search for resistance source against powdery mildew, seventy genotypes were evaluated under field conditions during Kharif and rabi 2015. Among seventy, the genotypes viz., DCA-1, DCA-2, DCA-3, DCA-4, DCA-5, DCA-6, DCA-7, DCA-8, DCA-9, DCA-10, DCA-11, DCA-12, DCA-13, DCA-14, DCA-22, DCA-23, DCA-24, DCA-25, DCA-26, DCA-35, DCA-42, DCA-44, DCA-45, DCA-57 and DCA-59 showed moderately resistant reaction during both kharif and rabi seasons and none of them were found resistant.
