- Abstract:
- With seven kinds of strong resistance of Xinjiang wild rose as the female parent,21 varieties of modern Chinese rose and 1 Rosa rugosa Thunb as the male parent.In this experiment,it adopted the conventional artificial pollination hybrid methods,73 hybrid combinations were designed,and 1 900 artificial pollination flowers were made,and 73 hybrid seeds and 1 146 hybrid seeds were obtained,and 323 seedlings were bred.The seed setting rate and seedling emergence rate of hybrid seeds were calculated,compatibility of interspecific crossing between Xinjiang wild rose and modern rose cultivars were studied.The results showed that 73 hybrid combinations,there were 29 combination hybrid fruit,Rosa ilicnsis,Rosa spinosissima L.var.altaica,Rosa laxa var.tomurensis,Rosa laxa Retz.as female parent and modern Chinese rose varieties seed setting rate was high,the affinity good performance;different combinations had different affinities,and there was no obvious rule.The best combination of affinity performance was Rosa ilicnsisבLove’；the combination of affinity performance was Rosa spinosissima L.var.altaicaבIncense of Greece’;affinity had good combination Rosa albertii Reg.×Rosa‘Beijinghong’,Rosa ilicnsis×Rosa‘Kadoyle’,Rosa ilicnsisבPerfume Delight’,Rosa ilicnsis×Rosa‘Beijinghong’,Rosa ilicnsis×Rosa rugosa Thunb,Rosa spinosissima L.var.altaica×R.cv.‘Goldmarie’,Rosa spinosissima L.var.altaica×Schloss mannheim,Rosa spinosissima L.var.altaica×Rosa‘Fenshan’,Rosa spinosissima L.var.altaica×Rosa ‘Beijinghong’,etc.,these combined hybrid seed setting rate of no less than 10%;from the analysis of the type of paternal variety,the affinity strength of the seven wild rose in Xinjiang was the Floribunda Roses>Big Flower Roses>Hybrid Tea Roses>Tree Roses.As the female parent of Rosa laxa Retz.,Rosa ilicnsis and Rosa laxa var.tomurensis with different Chinese rose as male parent varieties of hybrid seeds germination rate of female parent was obviously better than Rosa albertii Reg.and Rosa spinosissima L.var.altaica hybrid seeds germination rate.The seven species of wild rose Rosa laxa Retz.,Rosa ilicnsis and Rosa laxa var.tomurensis were more suitable for cross-breeding.
