Embodiment 1

[0014] A method for breeding a Rhododendron Camellia variety, the steps of which are as follows: with enriching flower color, flower type, and fragrant flowers as the breeding goals, during the flowering season of the male parent Rhododendron Red Camellia, select flowers that are ready to bud, remove the petals, and quickly remove them. All the stamens are smeared with pollen to be pollinated on the stigma, and the adhesive tape is folded in half to completely cover the stigma that controls pollination, so as to realize the controlled pollination of the Theaceae plant, and carry out hybrid seedling cultivation under indoor control conditions.

[0015] The invention aims at enriching flower colors, flower types and fragrant flowers, and rationally selects hybrid parents. According to the flowering habits of the male parent Camellia, determine the best pollen collection time; use low-temperature drying treatment to optimize pollen storage conditions; use different methods such as...

Embodiment 2

[0017] A method for breeding Rhododendron red camellia varieties, the method steps are as follows: by observing the phenotypes of naturally pollinated seedlings and artificial hybrid seedlings, selecting early excellent individuals, and adopting tissue culture technology to propagate the excellent individuals.

[0018] The rhododendron red camellia of the present invention has small population, few female parents, and low reproductive rate. For this reason, conventional breeding is difficult to expand its population in a short period of time, so it is difficult to develop and utilize this fine germplasm resource by conventional breeding. The tissue culture technology adopted in this project can solve this problem well: it can not only realize the protective utilization of the rare resource of Rhododendron red camellia, but also alleviate the scarcity of Rhododendron red camellia seedlings. First of all, field investigation and collection of existing resources should be carried...

Abstract

The invention discloses a camellia changii variety breeding method which comprises the following steps of selecting budding flowers by taking fragrant flowers with rich flower colors and flower types as breeding aims in a camellia changii male parent blooming season, poking petals, quickly removing all stamens, smearing pollens to be pollinated on stigmas, folding an adhesive plaster in two to completely cover the stigmas for controlled pollination to realize the controlled pollination of theaceae plants, and performing seed breeding of hybrids under an indoor control condition. The variety of camellia changii is small, the number of female parents is small, and the breeding potential is low. By a tissue culture technology disclosed by the invention, the problems can be well solved; rare and precious resources, namely the camellia changii, can be protectively used; the problem that the camellia changii seedlings are scarce can be alleviated.

Description

technical field [0001] The invention relates to a method for breeding rhododendron red camellia varieties, and belongs to the technical field of red camellia seedling cultivation. Background technique [0002] Rhododendron red camellia is an evergreen shrub to small tree. The height is 1-2m, the diameter at breast height is 5-10cm, the tree body is a short crown, and the branches and leaves of Rhododendron Camellia are dense and compact. The bark is taupe, the branches are smooth, the young shoots are red, the leaves are 8-12cm long, the ends are slightly pointed, obovate, leathery, the veins are not obvious, thick, bright green, the edges are smooth, not cracked, the petioles are short, little variation, The petals are narrow and long, the filaments are red, the anthers are golden yellow, and the flower diameter is more than 8 cm. Although the petals are single, the flowers are dense and plump as a whole. They bloom continuously in all seasons. Even in summer when the temp...
