摘要:
为了解小麦-簇毛麦抗白粉病易位染色体T6VS.6AL的遗传效应以更好地将其用于小麦品种选育，对扬麦18原始区域试验种子衍生的抗白粉病姊妹系、感白粉病姊妹系组群进行主要农艺和品质性状的比较。结果表明：T6VS.6AL易位对小麦的千粒质量、株高和穗长有极显著正向效应,对每穗小穗数呈显著正向效应,对小穗密度呈极显著负向效应,对单株总粒数、每穗粒数、单株穗数、株系产量没有显著影响；T6VS.6AL易位总体上对小麦品质没有影响。综上所述，高代姊妹系组群是准确评价特定染色体区段遗传效应的宝贵材料，在利用T6VS.6AL易位系进行滚动回交育种时，建议选择中矮秆、综合丰产性和广适性好的品种作为最晚轮回亲本。
Abstract:
In order to elucidate the genetic effects of wheat-Haynaldia villosa chromosome T6VS.6AL translocation for its application in wheat breeding, advanced sib-lines derived from the primitive seeds of Yangmai18 for variety regional test, were grouped according to powdery mildew resistance. Comparison between the resistant and susceptible groups was performed on major agronomic and quality traits. The results showed that T6VS.6AL has significantly positive effects on kernel weight, plant height, and spike length at the 0.01 level. It has significantly positive effect on spikelet number per spike and negative effect on spikelet density, at the 0.05 and 0.01 levels, respectively. It has no significant effect on kernel number per plant, kernel number per spike, tiller number per plant, and yield. Furthermore, T6VS.6AL has no effect on wheat quality generally. Based on the above results, it is concluded that sib line groups are valuable materials for precisely evaluating genetic effects of a certain chromosomal segment. Dwanf or medium-height stem, high-yielding and widely adaptable wheat varieties carrying translocated chromosome T6VS. 6AL are suggested to be used as the last recurrent parent during rolling convergent backcross.
