Three silkworm races including Chinese, Japanese and F1 (Korean) were studied when fed with three mulberry varieties including Husang China, Japan Early and Chinese Evergreen under laboratory conditions of 25 plus minus 2 degree C, 70 plus minus 10% RH and 16:8 (L:D) photoperiod at the Sericulture Wing of Forest Department, Shami Road, Peshawar during 2004-05. The interaction between races x varieties was found significant for larval, pupal and adult duration. Minimum larval (29.50 days), pupal (3.50 days) and adult (1.25 days) duration was noted in Chinese race on variety Husang China, while maximum larval (39.25 days), pupal (11.0 days) and adult (5.0 days) duration in F1 (Korean) race fed on variety Chinese Evergreen. Among the races and varieties individually, the results of larval, pupal and adult survival percentage was significantly different for both the B. mori races and mulberry varieties. The larval, pupal and adult duration individually was also significant for the races and varieties. The highest (36%) protein content was observed in Husang China variety. The Chinese race fed with Husang China mulberry variety exhibited the best performance due to the highest protein content.
