Abstract

A total of 162 numbers of entries found resistant to different diseases and insect pests in national and international nurseries were retested for one more year in elite barley disease screening nursery at hot spot locations from 2005–06 to 2007–08 crop seasons under artificially inoculated and disease epiphytotic conditions along with suitable susceptible checks. The diseases were stripe rust (Puccinia striiformis), leaf rust (Puccinia hordei), stem rust (Puccinia graminis), leaf blight caused by Bipolaris sorokiniana and Drechslera teres, powdery mildew due to Erysiphe graminis f. sp. hordei and cereal cyst nematode (CCN) caused by Heterodera avenae. The entries were also tested at seedling stage against different pathotypes of stripe, leaf and stem rusts at Flowerdale, Shimla. The genotypes resistant to rusts had average coefficient of infection (ACI) ranging from 0–10.0, for leaf blight average score of 35 was considered as resistant and for powdery mildew it was 0 score for resistance. For CCN, 0–4 cysts per plant were considered resistant to different genotypes. The following genotypes were found quite promising and may serve as resistant sources:
