| 摘 要： | 为研制具有自主知识产权的郁金香(Tulipa gesneriana)新种质, 本实验选择6种栽培郁金香品种为母本, 5种野生郁金香为父本进行杂交试验。结果显示, 平均受精率为(84.8±3.5)%, 母本受精率最高的是克斯奈丽斯, 平均为(94.0±2.3)%, 受精率最低的是蒙特卡罗, 平均为(71.0±3.8)%。果实发育1个月最高坐果率为100.0%, 平均为(75.2±4.1)%, 2个月最高坐果率为(90.0±3.6)%, 平均为(47.0±3.4)%; 杂交种子平均结实率为24.3%。研究结果表明, 母本与杂交组合对受精率、坐果率和结实率有显著影响, 父本则没有显著影响; 杂交组合小黑人×伊犁郁金香、小黑人×柔毛郁金香及小黑人×天山郁金香亲合性较
好, 其杂交种子结实率分别为78.2%、68.4%和57.5%。

| Abstract: | Cross-breeding experiments were carried out between 6 Tulipa gesneriana cultivars and 5 botanical Tulipa species from Xinjiang. The mean, maximum and minimum rates of fecundation were (84.8±3.5)%, 100.0% and (53.3±4.5)%, respectively. T. gesneriana ‘Kees Nelis’had the highest mean rate of fecundation (94.0±2.3)% and T. gesneriana ‘Monte Carlo’ the lowest (71.0±3.8)%. The highest rate of fruit bearing within 30 days after crossing was 100.0% and the mean rate was (75.2±4.1)% but decreased to (90.0±3.6)% and (47.0±3.4)%, respectively after 60 days. The mean rate of seed setting among the combinations was 24.3%. Both the effect of the 5 male parents and the difference among the 5 male parents on the cross characteristics were not significant, whereas the 6 female parents and the combinations of parents had significant effects on the cross characteristics. The favorable combinations were T. gesneriana ‘Negrita’×T. iliensis Regel, T. gesneriana ‘Negrita’×T. buheseana Boiss, and T. gesneriana ‘Negrita’×T. tianschanica Regel, with rates of seed setting being 78.2%, 68.4% and 57.5%, respectively. |
