| Abstract: | The 28 hybrids F, were studied between 8 glandless strains of cotton (Gossypium hirsutum L. ) in diallel croning system (Griffing 4). The hybrids F, showed an appreciable amount of heterosis. The highest check heterosis of seed cotton yield and lint yield were 27.74% and 24.59%, respectively. The analysis of combining ability variance indicated that there existed mere significant different in 10 characters in general combining ability and 5 characters in speeial combining ability among the tested parents. The analysis of combining ability effects displayed that Zhongwu 1051 and Zhongmiansuo 18 were better than the rest parents in effect of general combining ability of yield. And the lumian 16xZhongwu 3535 and the Zhongwu 1051 xZhongwu 3535 seemed to be the two ha combinations in many important agronomic characters. |
