Abstract: The present investigation was carried out to study heterosis of upland cotton (Gossypium hirsutum L.) at Surat, Gujarat. The magnitude of heterosis varied enormously for seed cotton yield and its attributing characters. The high magnitudes of standard heterosis was observed for lint index, bolls per plant and seed cotton yield per plant; whereas, sympodia per plant exhibited least heterotic values. The heighest possitive heterosis for seed cotton yield over better parent and standard check was observed to be 74.70 and 45.53 per cent, respectively. The cause of heterosis might be due to heterosis in its component traits, mainly bolls per plant, boll weight and seed index. The hybrids viz., GSHV-184 x GSHV-188, GSHV-184 x GSHV-192, GSHV-184 x G Cot 20, GSHV-192 x GN.Cot 22 and GSHV-188 x G Cot 20 displayed high per se performance, high significant and positive standard heterosis and heterobeltiosis for seed cotton yield and many yield contributing attributes, indicating that these hybrids may be utilized for further breeding programme as they likely to throw a desirable segregants.
