The present study was focused on the relationship between the yield and fibre quality traits to select the best GMS based hybrids. Thirty five GMS based interspecific tetraploid hybrids were raised from 5 lines (GMS14, GMS17, GMS19, GMS21, GMS27) and 7 testers (CCB26, CCB51, DB1901, CCB2, CCB6, CO18, SUVIN) in Line x Tester design and were evaluated for days to first flowering, days to 50% flowering, days to first bursting, plant height, boll weight, number of monopodia per plant, number of sympodia per plant, number of bolls per plant, ginning outturn, seed index, lint index, upper half mean length, uniformity index, bundle strength, elongation percentage and fiber fineness. The study of correlation on seed cotton yield for 18 traits reported that number of sympodia per plant, boll weight, ginning outturn, lint index, seed index, upper half mean length, uniformity index, bundle strength, elongation percentage and fiber fineness showed significant positive association with the seed cotton yield per plant. The path analysis resulted boll weight, ginning outturn, upper half mean length, elongation percentage, fibre fineness were exhibited positive direct effects on the seed cotton yield per plant. Hence, the above mentioned traits could be considered for further breeding programme.
