A field experiment was conducted during the Kharif season of 2016 at an oil seed research farm, C.S. Azad University of Agriculture and Technology, Kanpur, to see different cotton Bt hybrids and non-Bt varieties on growth, yield attributes and seed cotton yield in hirsutum cotton. Data indicated that all the yield attributing characters viz number of bolls per plant and boll wt (g)were improved significantly with Bt hybrids than non-Bt varieties. Bt hybrid 6588 BG II produced significantly higher seed cotton yield (3427 kg/ha) and lint yield (1232 kg/ha) than 6488 BGII, and this yield was at par with Bio -100 (3301 and 1201 kg/ha), Bio-105 (3382 and 1212 kg/ha) and Yuva plus (3249 and 1197 kg/ha) seed cotton yield and lint yield, respectively and gave 22.6% more seed cotton yield and 22.1 % more lint yield than 6488 BGII (2795 and 1009 kg/ha), respectively. Variety F-1861 was found significantly superior in seed index (8.40 g) and lint index (4. 36) compared to the rest of Bt hybrids and non-Bt varieties. Significantly higher GOT% (35.9%) was obtained with the Bt hybrid (6588 BGII) compared to the non-Bt varieties and 6488 BGII. However, the highest 2.5 span length (30.9 mm) with Yuva plus BGII followed by Bio -105 BGII (30.4 mm) was noted compared to the non-Bt varieties and Bt hybrids.
