Abstract

The invention discloses a breeding method of a purple chili selfing line and belongs to the technical field of plant breeding. The breeding method comprises the following steps: (1) preparing red F1-generation hybrid seeds by red and yellow chilies; (2) taking the generation F1 as a male parent or a female parent to be hybridized with green chilies to obtain three-way hybridized seeds; (3) taking the green chilies as a male parent or a female parent to carry out backcross on the red three-way hybridized seeds to prepare a generation BC1; (4) selecting green single plants from a BC1-generation segregation population and carrying out selfing to obtain BC1F2-generation seeds; (5) selecting purple chilies from a BC1F2-generation segregation population, carrying out selfing and reserving seeds; and (6) carrying out 3-5 generation selfing and homozygosis to obtain the purple chili selfing line. The invention provides a novel breeding manner for the establishment of purple chili germplasm resources, and purple chili hybrid seeds with obvious advantages can be further cultured by using the novel breeding manner; and the breeding method can be popularized and applied in the aspects of breeding and production.

Description

technical field [0001] The invention relates to the technical field of plant breeding, in particular to a method for breeding purple pepper inbred lines. Background technique [0002] Capsicum (Capsicumannuum L), Solanaceae, Capsicum genus, is an annual or limited perennial herb. The fruit is usually conical or oblong, green when immature, and bright red, green or purple when ripe, with red being the most common. Pepper is one of the most important vegetable crops in the world. The global pepper planting area is 55 million mu, while China's pepper planting area is 23 million mu. It is the world's largest pepper producer and major consumer country, and is also one of the countries with the largest pepper export , the average yield per mu is more than 1000 kg. [0003] The existing purple pepper varieties are mainly lantern-shaped sweet pepper series produced by foreign seed companies, while my country mainly consumes peppers; at the same time, under the condition that peppe...
