Abstract:

Artificial cross-pollination was carried out to cultivate new varieties of high-value Camellia, which provided a reference for development and utilization of rare Camellia in introduction, landscape, tea-drinking and other aspects. Six Camellia plants were used as parents to carry out cross-pollination, and the situation of seed setting and F1 generation seedlings were counted. The morphological identification and molecular identification of F1 generation seedlings were executed by SSR technology. The results indicated that characteristics of leaf shape, vein and serration of F1 generation seedlings were closer to female parent, the leaf shape and size, serration and leaf luster were neutral, and the overall morphology of the leaves was more similar to male parent. SSR molecular identification showed that seedlings 2-3 and 14-1 were self-crossed, and 1-1,1-2,1-4,1-5 and 9-4 appeared new hybrid bands, which were identified as alien blood, while the remaining 14 F1 seedlings were identified as real hybrids. In the future, the number of primers and the range of hybrid combinations can be expanded, and the genetic stability of excellent traits of real hybrids can be continuously tracked to provide more comprehensive support for directional breeding of Camellia.
