Embodiment 1

[0040] A method for breeding purple fast vegetables, comprising the following steps:

[0041] 1. Cultivate purple inbred varieties:

[0042] The purple cabbage inbred line was used as the female parent and the green fast vegetable inbred line was used as the male parent to carry out cross breeding to obtain a purple hybrid plant; then the purple hybrid was used as the female parent and the green fast vegetable inbred line was used as the Backcross the male parent, adopt the method of artificial pollination at the flower bud stage for backcross breeding, the first generation of backcross selects an excellent purple plant whose main traits are similar to the green fast vegetable inbred line used as the male parent, and is identified and combined in the field Agronomic traits were selected to obtain a purple inbred variety I with stable traits. The purple inbred variety Ⅰ has purple leaves on the front, green on the back of the leaves, purple petioles, and purple flower stems an...

Embodiment 2

[0048] A method for breeding purple fast vegetables, comprising the following steps:

[0049] 1. Cultivate purple inbred varieties:

[0050] The purple cabbage inbred line was used as the female parent and the green fast vegetable inbred line was used as the male parent to carry out cross breeding to obtain a purple hybrid plant; then the purple hybrid was used as the female parent and the green fast vegetable inbred line was used as the Backcross the male parent, adopt the method of artificial pollination at the flower bud stage for backcross breeding, select purple excellent single plants whose main traits are similar to those of the green fast vegetable inbred line as the male parent, and identify and combine in the field Agronomic traits were selected to obtain a purple inbred variety I with stable traits. The purple inbred line variety I has purple leaves on the front, green on the back of the leaves, purple petioles, leaves growing on the petioles, and cracks on the edg...

Embodiment 3

[0056] A method for breeding purple fast vegetables, comprising the following steps:

[0057] 1. Cultivate purple inbred varieties:

[0058] The purple cabbage inbred line was used as the female parent and the green fast vegetable inbred line was used as the male parent to carry out cross breeding to obtain a purple hybrid plant; then the purple hybrid was used as the female parent and the green fast vegetable inbred line was used as the Backcross the male parent, adopt the method of artificial pollination at the flower bud stage for backcross breeding, backcross 8 generations to select purple excellent single plants whose main traits are similar to those of the green fast vegetable inbred line used as the male parent, after field identification and combination Agronomic traits were selected to obtain a purple inbred variety I with stable traits. The front of the leaves of the purple inbred variety I is purple, the back of the leaves is green, the petiole is purple, there are...

Abstract

The invention provides a breeding method for a purple Chinese cabbage. The breeding method for the purple Chinese cabbage comprises the steps that a, a purple selfing line variety is breeded, i.e., a purple Chinese cabbage flower stalk selfing line serves as a female parent, a green Chinese cabbage selfing line serves as a male parent, and crossbreeding is conducted to obtain a purple cross breed; and the purple cross breed serves as a female parent, a green Chinese cabbage selfing line serves as a backcross male parent, back cross breeding is continuously conducted, and a plant with the first target trait stable is selected as the purple selfing line variety I; b, a purple non-heading pakchoi selfing line variety is breeded, i.e., a purple cabbage selfing line serves as a female parent, a non-heading pakchoi selfing line serves as a male parent, back cross breeding is continuously conducted, and a plant with the second target trait stable is selected as the purple selfing line variety II; and c, a purple Chinese cabbage variety is breeded, i.e., the purple selfing line variety I serves as a female parent, the purple selfing line variety II serves as a male parent, and crossbreeding is conducted to obtain the purple selfing line variety. The purple Chinese cabbage is short in growth period, long in shelf life, high in heat resistance, good in quality and high in yield.

Description

technical field [0001] The invention relates to the technical field of fast vegetable breeding, in particular to a method for breeding purple fast vegetable. Background technique [0002] There are many varieties of green fast food on the market, and the demand is huge. With the residents' demand for vegetable diversity, the innovation of purple fast vegetable breeding resources has become a direction for breeders. At present, purple non-heading Chinese cabbage, purple cabbage, purple cabbage, and purple rapeseed have come out one after another. However, these varieties have a long growth period and cannot meet the huge market demand. [0003] Purple non-heading pak choy, purple cabbage, purple cabbage and fast cabbage are all species or subspecies of Brassica in the family Brassicaceae. It is relatively easy to hybridize within each species and subspecies, but it is difficult to hybridize between species. Among them, the varieties of purple non-heading pakchoi are mostly ...
