The study was undertaken to evaluate the magnitude of heterosis in 36 cotton hybrids developed by crossing 3 lines and 12 testers in L x T design at three different locations of Maharashtra State viz., Akola, Amravati and Nagpur during kharif, 2017-18. The cross AKH 8828 x AKH 9916 exhibited highest and significant heterosis over the check PKV Hy-2 for seed cotton yield/plant (60.30 %), number of bolls/plant (23.55 %) and fibre strength (10.43 %) across the environments. The cross AKH 081 x AKH 09-5 exhibited higher and significant standard heterosis (54.05 %) for seed cotton yield/plant in association with other economically important traits. Similarly, other crosses viz., AKH 84635 x SURAJ (47.76 %), AKH 8828 x AKH 2006-2 (47.12 %) and AKH 8828 x DHY 286 (45.79 %) also exhibited higher significant heterosis over the check hybrid PKV Hy-2 for seed cotton yield/plant in association with other yield contributing characters. The cross AKH 84635 x AKH 2012-8 exhibited considerable heterosis for seed cotton yield/plant and fibre quality parameters. These promising crosses have immense value to exploitation at commercial level after thorough multilocation testing.
