Genetic Diversity and Its Correlation with Heterosis of Upland Cotton (Gossypium hirsutum L. ) Cultivars of Huang-Huai Region in China Evaluated by RAPD

摘要

Sixteen cultivars of Upland cotton（Gossypiumhirsutum L.）cultivars in Huang-Huai Cotton-growing Region were detected by RAPD whilethe F1 heterosis of each hybrid involved thesecultivars were evaluated.The genetic similarity（GS）of the 16 cultivars through analysis of 115polymorphic RAPD loci obtained from 70informative primers were 53%～88%.
