摘　　要：T.spelta1BS染色体导入1B/1R类型K型小麦不育系及其保持系,育成非1B/1R类型K型小麦不育系及其保持系,通过对两种类型不育系及其保持系的主要农艺性状、产量性状及抗条锈病的比较,对T.spelta1BS染色体的遗传效应进行了初步研究。结果表明T.spelta1BS染色体导入使非1B/1R类型K型小麦不育系及其保持系株高明显增加,穗长、小穗数、单穗粒数、自交结实率均无明显差异,抗条锈病能力有增强的趋势,但对白粉病的抗性没有明显影响,在主要产量性状方面均无不利的遗传效应。T. spelta 1BS chromosome piece was inducted the K wheat male-sterile lines and maintenance lines, nurtured non- 1B/1R the type K wheat male-sterile line and maintenance lines, determined and compared two types main agronomies, the output character and the anti- strip rust ability. The result indicated, T.spelta 1BS chromosome piece induction caused non-1B/1R the type K wheat male-sterile line and its b-line had the obvious superiority in a high aspect, not obvious difference in the spike length, No. of spikelets per spike,No, of grains per ear,seed set in selling and the disease resistance of powdery mildew, but the anti- strip rust ability had the obvious enhancement, in main output character aspect not disadvantageous genetic effect.
