- Abstract
Rice leaf folder has attained the status of major pest from previous few years in Punjab Province. No rice genotype has been reported to carry highly resistance against rice leaf folder. This experiment were conducted in Institute of Agriculture Science University of the Punjab, Lahore during 2016. Randomized complete block design was used having three replications. Out of 34 genotypes 13 course, 12 fine aromatic and 9 fine non aromatic genotypes were selected. Five weeks data showed that in coarse varieties highest leaf folder infestation were recorded on C-9 (18.18% ± 3.27), Sonahri (17.86% ± 2.80), Nile (16.63% ± 3.12) and lowest infestation were found on KSK-133(12.54% ± 1.53), KS-282 (12.44% ± 1.99), Rondo (12.01% ±1.80) while in fine varieties highest leaf folder infestation were recorded on fine aromatic varieties Kashmir-basmati (11.36 % ± 1.81), Basmati-515 (11.36 % ± 1.81), Dhakan,(10.76 % ± 1.65) and Kasalath (9.89 % ± 1.46 ); lowest leaf folder infestation were observed on fine non aromatic 7260 (5.51 ± 0.94 ) and 7240 (4.92 ± 0.79 ). All other varieties showed intermediate leaf folder infestation. According to IRRI Standard Evaluation system (SES) of rice damage rating scale, our results indicates that only 4 varieties were found moderately resistance with rating scale 3 and all other varieties were found resistance with rating scale 1. It is concluded that KSK-133, KS-282, Rondo and fine non aromatic 7260, 7240 having least infestation of rice leaf folder should be grown in rice grown areas of Punjab, Pakistan.
