Studies on heterosis in cotton interspecific heterotic group hybrids (G.hirsutum X G.barbadense) for seed cotton yield and its components

Line × tester analysis was undertaken to assess the magnitude of heterosis in 32 interspecific heterotic group hybrids (G. hirsutum x G. barbadense) of cotton for seed cotton yield and its components developed by crossing eight elite hirsutum lines with four elite barbadense testers during Kharif 2010-11 at Main Agricultural Research Station, Dharwad.
