Evaluation of bell pepper (Capsicum anrzuzcm) germplasm for resistance to leaf blight and fruit rot caused by Phytophthora nicatianae var nicotianae.

Abstract

Out of twenty eight cultivars / lines evaluated for resistance to leaf blight and h i t rot (Phytophthora nicotianae B. de. Hann var. nicotianae Waterhouse) of bell pepper under field as well as laboratory conditions, only 1 line, ie DG was found resistant while rest were moderately resistant to highly susceptible. Higher degree of horizontal resistance was present in the moderately resistant lines 'HC 201' and 'Feroz' as reflected by slowest and moderate apparent infection rate, respectively under field conditions besides comparatively longer incubation periods under laboratory conditions.
