| 摘 要： | Fspelta 1BS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．spelta 1BS染色体的遗传效应进行了初步研究。结果表明tspelta 1BS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。

| Abstract: | 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 selfing 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. |
