Thirty two genetic male sterility based intra arboreum cotton hybrids were evaluated against the hybrid check AAH-1 during kharif2020 at Cotton Research Area, CCS Haryana Agricultural University, Hisar for yield and its attributes. The analysis of variance revealed that the hybrids differed significantly for all the characters under study indicating presence of considerable genetic variability between the genotypes. These hybrids exhibited heterosis over standard check for all the traits studied. Correlation analysis showed significantly higher and positive correlation between seed cotton yield and lint yield describing corresponding increase in lint yield with the increase in seed cotton yield. Eight hybrids viz., GMS 1 x HD 535, RGMS 5 x GCD 91, GMS 1 x HD 548, GMS 1 x GCD 308 (AAH38), RGMS 5 x HD 535, GMS 1 x DMP 44 (AAH 44), GMS 1 x NP 15 (HD 123 x HD 462) (AAH 43) and RGMS 5 x HD 544 were found promising based on significantly higher seed cotton yield and standard heterosis. Therefore, these promising cross combinations can be exploited for their hybrid vigour.
