摘要： 为研究白蜡树属种间杂交不同亲本对杂种F1代种子的影响，设计白蜡树属不同种间杂交组合36个，收集各杂交组合F1代种子，统计种子的千粒重、翅长、翅宽和翅长/翅宽等特征表型性状数据，使用SPSS 24.0软件对数据进行方差分析，比较种间杂交种和种内杂交种差异以及种间杂交不同基因型母本与父本对杂交种性状的影响。结果显示：以美国红梣为母本与不同种的白蜡父本杂交，种间杂交与种内杂交F1代种子4项指标差异明显，种间杂交各组合间变异幅度较大；以绒毛白蜡为母本与不同种的白蜡父本杂交，种间杂交与种内杂交F1代种子性状总体差异不显著。4个基因型绒毛白蜡为母本与水曲柳杂交，F1代种子性状发生显著变异；5个基因型绒毛白蜡为父本与美国红梣杂交，F1代种子千粒重性状差异较大；以不同基因型水曲柳为父本分别与美国红梣、绒毛白蜡杂交，绒毛白蜡为母本的杂交组合获得的F1代种子性状变异优于美国红梣为母本的杂交组合。研究表明，白蜡种间杂交F1代种子发生了较为丰富的遗传变异，绒毛白蜡为母本种子遗传变异高于绒毛白蜡为父本的种子遗传变异，不同基因型水曲柳为父本对F1代种子性状影响不明显。研究可为白蜡树属种间杂交亲本选择提供参考，进一步提高了白蜡育种效率。

Abstract:

To investigate the effects of different parents in interspecific hybridization of the genus Fraxinus on hybrid F1 seeds, a total of 36 interspecific hybridization combinations of the genus Fraxinus were designed, and F1 seeds from various hybrid combinations were collected. Statistical analysis of characteristic data such as thousand seed weight, wing length, wing width, and wing length/width of seeds was conducted. SPSS 24.0 software was used to perform variance analysis on the data, comparing the differences between inter species hybrids and intra species hybrids, as well as the effects of different genotypes of maternal and paternal parents on hybrid species. The results showed that there were significant differences in the four indicators of F1 seeds between interspecific hybridization and intraspecific hybridization when F. pennsylvanica was used as the maternal parent and different species of Fraxinus male parent. The variation range between different combinations of interspecific hybridization was large. However, when using F. velutina as the maternal parent and different species of Fraxinus male parent, there was no significant overall difference in seed traits between interspecific hybridization and intraspecific hybridization. Four genotypes of F. velutina were hybridized with the female parent of F. mandshurica, resulting in significant variations in seed traits in the F1 generation. Five genotypes of F. velutina were hybridized with the male parent of F. pennsylvanica, resulting in significant differences in thousand seed weight traits in the F1 generation; The F1 seed trait variation obtained by crossing the male parent of F. mandshurica with and the female parent of F. velutina was superior to that of the hybrid combination with F. pennsylvanica as the female parent. The results showed that the F1 hybrid seeds in the interspecific hybrid of the genus Fraxinus had abundant genetic variation. Overall, it is believed that the variation of hybrid seeds with F. velutina as the maternal parent is higher than that as the paternal parent. Different genotypes of F. mandshurica as the paternal parent have no significant effect on the seed traits of F1 generation. The study provides a reference for the selection of parents for interspecific hybridization in the genus Fraxinus, further improving the efficiency of Fraxinus.
