An field experiment was conducted at Cotton Research Unit, Department of Agricultural Botany, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during Kharif 2007-2008 to estimate heterosis for seed cotton yield and fibre quality parameters. Twenty two hybrids were obtained by crossing two lines and eleven testers in a line × tester mating design. These parents and hybrids were grown in Randomized Block Design with three replications. The parents vs. hybrids indicated substantial amount of heterosis present in the population. Among 22 hybrids, hybrid AKH-0601 × BBP-1 exhibited highest economic heterosis (52.4%) for seed cotton yield which was followed by AKH-0601 × BBP-6 (47.5%) and AKH-0601 × BBPSPS-25 (45.9%). These hybrids also exhibited significant and desirable standard heterosis for yield components traits as well as for fibre quality parameters.

Abstract


An field experiment was conducted at Cotton Research Unit, Department of Agricultural Botany, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during Kharif 2007-2008 to estimate heterosis for seed cotton yield and fibre quality parameters. Twenty two hybrids were obtained by crossing two lines and eleven testers in a line × tester mating design. These parents and hybrids were grown in Randomized Block Design with three replications. The parents vs. hybrids indicated substantial amount of heterosis present in the population. Among 22 hybrids, hybrid AKH-0601 × BBP-1 exhibited highest economic heterosis (52.4%) for seed cotton yield which was followed by AKH-0601 × BBP-6 (47.5%) and AKH-0601 × BBPSPS-25 (45.9%). These hybrids also exhibited significant and desirable standard heterosis for yield components traits as well as for fibre quality parameters.
