Abstract
Forty-five hybrids from 10 x 10 diallel of Gossypium arboreum L. genotypes were tested with their parents at Anand in kharif, 2006 for Heterobeltiosis and Standard heterosis. The heterobeltiosis for seed cotton yield ranged from -32.48 to 154.2 per cent and the value of standard heterosis ranged from -39.05 to 41.89 per cent. The hybrid CINA-343 x Jawahar Tapti (higher economic heterosis) and hybrids CINA-333 x CINA-344 and CINA-329 x DLSA-17 (high Heterobeltiosis) were the promising hybrids identified in this study for seed cotton yield per plant. The desirable heterosis was also observed in the cross combinations viz; CINA-344 x 824 for boll weight, number of sympodia per plant and number of bolls per plant; CINA-333 x CINA 344 for number of sympodia per plant and number of bolls per plant.
