The present study was carried out with 26 derived lines for shoot fly resistance and three checks, to estimate the various variability parameters and heritability. Two sets of planting were done, first planting was done to record observations on yield and yield contributing traits. Second planting was done for screening of shoot fly reaction under artificial epiphytic conditions; late planting technique and infector row technique were used for creating sufficient shoot fly pressure. The analysis of variance revealed that significant difference among genotypes for all the traits, suggesting presence of wide range of variation among the genotypes for all the characters under study. Mean values for the lines AKENT - 101, AKENT - 104, AKENT - 107, AKENT - 117, AKENT - 123, AKENT – 125 and IS 18551, showed shoot fly reaction, these lines exhibiting comparatively low number of eggs per plant, minimum  dead  heart  count, low chlorophyll content index and high trichome density per mm2. High heritability (broad sense) was recorded for trichome density per mm2 due to high additive gene action.
