HETEROSIS IN INTRA-GOSSYPIUM ARBOREUM L. COlTON HYBRIDS

Published on

Maximum heterosis for seed cotton yield was shown by cross LO 135 X HO 31 (67.6%).
Crosses Vimar x HD 31 (64.4%), AKH 4 x HD 31 (60.9%), Oaulat x G 1 (58.9%), LO 133 x
Shyamali (57.1%), St877 x HD 31 (52.6%), RG 3 x RG 2 (51.2%), LO 133 x HO 31 (SO.6%) and
LO 133 x RG 2 (SO.I%) also showed exploitable heterosis. These crosses also exhibited
significant heterosis for yield components. However, heterosis for halo length was low.
