摘要: 对从粗山羊草(DD)与硬粒小麦(AABB)合成的Am6双二倍体(AABBDD)后代中选育的30个株系的农艺性状和细胞学特点进行了分析.结果表明,30个株系在分蘖力、单株成穗数、抗病性、穗长等性状方面表现优异,在小麦遗传改良中具有利用价值.但大部分材料仍表现出一定的细胞学不稳定性.

关键词: 性状, 细胞学, 粗山羊草, 双二倍体

Abstract: The studies on agronomic traits and cytologic characteristic of 30 wheat lines selected from the posterity of Aegilops tauschii ( DD)一Triticam carthlicum ( AABB ) amphiploid ( AABBDD ) Am6 were carried out. Results showed that the 30 wheat lines have many excellent characters, such as multi-tillers, multi-spikes per plant, good disease resistance, large ear,etc.They are very useful in hereditary improvement of wheat.But many of them still display unstable in cytology.

Key words: Character, Cytology, Aegliops tauschii(coss)Schmal, Amphiploid
