Abstract: The present investigation was carried out with half diallel analysis involving 10 parents and their 45 F1 hybrids to estimate the heterosis for fibre quality traits. The hybrid Pusa 9127 x BS 277 recorded highest heterobeltiosis (8.23) for 2.5% span length and hybrid BS 2170 x TCH 1728 exhibited positive significant relative heterosis (9.09%) for uniformity ratio. hybrid GSHV 99/ 307 x TSH 0250 (32.26%) showed significant positive heterobeltiosis for miconaire while hybrid CCH 510 x BS 2170 (18.25%) for strength to length ratio appears to be most superior hybrids.
