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...
