摘要: 用激素处理和染色体加倍的方法获得陆地棉与比克棉、色伯氏棉等野生棉种的远缘杂交后代,结合杂交、回交、聚合杂交的手段,使棉花远缘杂种后代的品质性状得到了显著的提高.为了克服棉属种间杂交后代疯狂分离的难题,使新品系的性状尽快稳定,通过半配合材料VSG作母本与之杂交,得到远缘杂种后代低代材料的单倍体,通过染色体加倍等手段得到了稳定的优质棉新品系.

关键词: 陆地棉, 野生棉, 远缘杂交, 单倍体, 染色体加倍

Abstract: Distant hybrid progeny were obtained through Holman treatment and chromosome duplication. Combined with methods of crossing, backcrossing and polymerization, quality trail of those distant hybridization have been remarkabelly improved. To overcome excessive segregation and make new trail stable, cross was made with semigamy VSG as female parent and haploid of hybridization's lower generations were got and stable fine quality new species were developed through measures like chromosome duplication.

Key words: G.hirsutum, Wild cotton, Distant hybrid, Chromosome duplication
