Abstract: The present study was carried out with forty five intra hirsutum cotton hybrids over three locations viz., Regional Agricultural Research Station, Lam Farm, Guntur; Agricultural Research Station, Jangamaheswarapuram and Agricultural Research Station, Darsi of Andhra Pradesh, India during kharif 2013-14 to study the Genotype × environment interaction on fibre quality traits like 2.5% span length, bundle strength, fibre elongation, uniformity ratio, and micronaire in cotton using Additive Main Effects and Multiplicative Interaction Model. Analysis of variance was significant for all the quality traits and environments and (G x E) components indicating the use fullness of AMMI analysis in identifying the stable genotypes. The analysis also partitioned the total G x E component into IPCA1 and Residual. Among the hybrids, BBGH-77 x BBGH-33 for bundle strength and micronaire, BBGH-77 x BBGH-1 and BBGH-3 x BGH-94 for fibre elongation and micronaire are found to be highly stable over environments and can be exploited for commercial cultivation after thorough testing and over locations and years for these important quality traits.
