Heterosis studies for yield and fibre quality traits in American cotton (Gossypium hirsutum L.)
In the present study forty five intra-hirsutum hybrids along with their parents and standard check were evaluated to estimate the magnitude of heterosis for yield and fibre quality traits at Regional Agricultural Research Station, Lam, Guntur during Kharif, 2017-18. The standard heterosis was calculated over check hybrid, LAHH 5. The hybrid combinations, SCS-1207 × GSHV-177, GSHV-177 × L1231 and SCS-1207 × PBH-13 were found to be promising for seed cotton yield plant-1 along with majority of yield components and fibre quality traits in terms of standard heterosis. These genotypes may be evaluated over locations for further confirmation of their superiority for exploiting them commercially.
