部分蔷薇和现代月季杂交亲和性
Compatibility of Crosses between Rosa multiflora and Rosa hybrida

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 hybridization of 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 hybridization between same type of Rosa hybrida mainly occurred at the late stage (3 months after pollination), while for wild × cultivar crosses and different type of cultivar × cultivar crosses, serious abscission occurred at both stage (1 month after pollination and 3 month after pollination) , which were corresponded to the results of cross compatibility.
