Abstract

The invention relates to a breeding method of a primula forbesii variety, which comprises the following steps: selecting two plants as parent from primula forbesii cultivation groups with the same flower color and flow model, wherein one plant is a long stigma flower and the other plant is a short stigma flower; then carrying out emasculation, bagging, pollen acquisition, artificial pollination, bag removal and harvesting and breeding of double-cross seeds; and finally repeatedly hybridizing and breeding for 3-4 years to obtain the primula forbesii variety which has consistent phenotypic expression, stable heredity and no segregation character phenomenon. The breeding method can effectively fix the character, enable various single plants in the breed to tend to be homozygous and solve the breeding difficult problem caused by self-incompatibility; and besides main target characters (flower colors and flower models) are obtained, other fancypoints such as flower diameter and the like can be greatly improved, the progeniture flow diameter is gradually increased and the ornamental value can be further improved.

[0001] The invention belongs to the field of plant breeding, in particular to a breeding method for Primula forbesii Franch. varieties. Background technique

[0002] Primula is one of the world's three most famous alpine flowers, and is famous all over the world for its gorgeous flower colors. There are about 500 species of primroses in the world, and there are nearly 300 species in China, which is the modern distribution center of primroses. But so far there are few new varieties of primroses with my country's independent intellectual property rights coming out. One of the reasons is that primroses have self-incompatibility, and many excellent ornamental characters cannot be expressed uniformly, let alone stably inherited.

[0003] Small Primula (Primula forbesii Franch.) is a unique plant of the Primula family Primulaceae in my country. It is native to the Yunnan region of my country at an altitude of 1500-2000m. Primula forbesii Franch. is a biennial he...
