- Abstract
The rice leaf folder, Cnaphalocrocis medinalis Gueee (Lepidoptera: Pyralidae), is major leaf feeding pest of rice, Oryza sativa L. (Poaceae), and is widely distributed throughout the rice producing countries in Asian, causing considerable yield losses. Cultivation of susceptible rice varieties is among the major reasons of insect pest outbreak. Contrary, growing resistant rice varieties plays a key role in keeping the insect pest population below economic threshold level. Growing resistant varieties is considered as safe and cost-effective method for the control of (RLF). Keeping in view the importance of the pest and economic value of the crop this experiment is designed to screen thirty five genotypes for resistance against rice leaf folder. These genotypes were evaluated for resistance against RLF in green house in the Department of Plant Breeding and Genetics, Agriculture University Peshawar, by following the method of Heinrichs et al. (1985). In our findings the screened genotypes falls in to different categories as 16 genotypes are highly susceptible, 6 are susceptible, 5 are moderately susceptible, 5 are moderately resistant, and only 3 tested genotypes proved resistance against the Cnaphalocrocis medinalis while none of the screened genotype falls in the category of highly resistance against RLF. These resistant genotypes can be used in future IPM program for the management of RLF. Furthermore, these resistant germplasms can be used in breeding programs for the development of high yielding resistant varieties against RLF.
