摘　　要：为丰富国内自育品种并解决现代月季夏季病害严重开花不良的问题,2011-2012年对蔷薇与月季品种杂交、杂种香水月季品种间杂交及不同类型月季品种间的63个组合的杂交进行研究,分析不同组合结实情况,发现杂种香水月季品种间杂交亲本亲和性较好,而蔷薇与月季品种的杂交亲和性较差。同时通过对38个组合的坐果情况跟踪观察,得出杂交果落果规律,月季杂交的落果时期主要出现在授粉后1月内及授粉3个月后。从亲和性分析这些组合的落果情况,同一类型品种间杂交果实严重落果期集中于果实成熟后期(授粉3个月后),而另外2类组合严重落果期在前(授粉1个月内)、后期(授粉3个月后)均有分布,与结实情况表现的亲和性一致。In order to enrich domestic bred varieties of modern Rosa hybrida, solve the serious disease and bad flowering in summer, 63 crosses were made between once-flowering rose and different rose varieties from 2011 to 2012. The results of cross compatibility analysis showed that： intra-variety hy- bridization o{ Hybrid Tea Roses had higher fruit setting rate, and lower fruit setting rate was detected in the hybridization between wild rose and Rosa hybrida. Furthermore, fruit abscission in hybridiza- tion between same type of Rosa hybrida mainly occurred at the late stage （3 months after pollina- tion）, while for wild × cultivar crosses and different type of cultivar × cultivar crosses, serious ab- scission occurred at both stage （1 month after pollination and 3 month after pollination） , which were corresponded to the results of cross compatibility.
