利用3类试验材料,即由不同生态类型的推广品种与小麦-簇毛麦6VS/6AL易位系经过杂交回交选育的高代品系(种),3份涉及6VS/6AL的高代分离品系以及5个以小麦-簇毛麦6VS/6AL易位系作杂交亲本的F2群体,对含有与不含有6VS/6AL易位染色体材料的产量、株高、穗长、穗粒数、穗粒重和千粒重等农艺性状进行方差分析。结果表明,6VS/6AL易位染色体对后代的小穗数、穗粒数、穗粒重和产量等农艺性状没有表现出明显的影响,对穗长和千粒重表现出一定的正向效应。多数6VS/6AL衍生品系的株高与亲本相比有所增加,但在同一组合的不同品系之间表现出一定的差异,在育种过程中通过选择可改变增高趋势。6VS/6AL易位系对白粉病免疫,并且遗传稳定,对小麦的抗病育种是很有潜力的抗源亲本。
Three high-yielding lines (hybrids) were selected from three types of experimental materials, ie, hybrids backcrossed with 6VS / 6AL translocation lines of different ecological types and wheat- And F2 population of 5 crosses with 6VS / 6AL translocation lines of wheat-Hsiaomei were studied. The yield, plant height, spike length, number of grains per spike, grain number per spike Weight and grain weight agronomic traits analysis of variance. The results showed that the 6VS / 6AL translocation chromosome had no significant effect on the agronomic traits such as spikelet number, grain number per spike, grain weight and yield of progenies, but showed some positive effect on the spike length and 1000-grain weight. The majority of 6VS / 6AL derived lines increased their plant height compared with their parents, but showed some differences among different lines of the same combination, which could be changed by breeding. The 6VS / 6AL translocation line is immune to powdery mildew and is genetically stable, which is a potential anti-source parent for disease-resistant breeding of wheat.
