Problems solved by technology

[0003] However, although the heat-resistant varieties of the common non-heading Chinese cabbage (the kind with green petiole in the Chinese cabbage subspecies common cabbage variety) have the advantages of high temperature resistance, they can realize continuous cultivation and increase yield, but they have slow growth rate and rough fiber. Many, poor taste defects, it is difficult to meet people's demand for non-heading cabbage with excellent heat resistance

Embodiment 1

[0046] 1. Breeding of the female parent Pleurotus chinensis

[0047] Select 36 parental materials (as shown in Table 1) of the high-generation strains of excellent Pleurotus chinensis to sow on July 8, 2016, and identify disease resistance, heat resistance and proterties, and identify disease resistance, heat resistance The seeds of the plants with traits and traits were sown on November 25, 2016, and the affinity index was measured in the early spring of 2017. At the same time, the traits and disease resistance of the plants were investigated, and those with disease resistance and heat resistance were identified and screened in summer and spring. 3 copies of self-incompatible lines (Q-34-3, Q-2-85, Q-9-4), erect plant type, small leaves, dark green glossy leaves.

[0048] 2. Breeding of male parent Chinese cabbage

[0049] Select 34 parental materials of high-generation Chinese cabbage lines (as shown in Table 2) and sow on July 8, 2016, and identify disease resistance, heat...

Abstract

The invention belongs to the technical field of hybridization breeding, and particularly relates to a breeding method of disease-resistant, heat-resistant, fast-growing and good-taste non-heading Chinese cabbages. The breeding method provided by the invention comprises the following steps: taking green cabbages with strong disease resistance, strong heat resistance and excellent characters as female parents, and taking fast-growing Chinese cabbages with strong disease resistance, strong heat resistance and excellent characters as male parents; hybridizing the male parents and the female parents to obtain hybrid seeds; identifying and screening plants grown after the hybrid seeds are sown to obtain the non-heading Chinese cabbages which are disease-resistant, heat-resistant, fast-growing and good in taste. The bred non-heading Chinese cabbages can resist the high temperature of 38 DEG C or above and resist various diseases such as soft rot, black rot and anthracnose, the average growth time is 30-35 d, the weight of a single plant is 80 g or above, the average plant height is 25 cm, the development degree is 25 cm, leaves are obovate, the leaf surface is flat, outer leaves are green and glossy, petioles are green and white, the content of crude fiber is low, the taste is good, and the yield per mu is 2000 kg or above.

Description

technical field [0001] The invention belongs to the technical field of hybridization and breeding, in particular to a method for breeding non-heading Chinese cabbage with disease resistance, heat resistance, fast growth and good taste. Background technique [0002] Non-heading Chinese cabbage is a subspecies of Brassica cabbage in the family Brassicaceae. It mainly uses leaves and petioles as edible organs. It has a variety of varieties and has achieved annual production. At present, the cultivation area of ​​non-heading Chinese cabbage is increasing. [0003] However, although the heat-resistant varieties of the common non-heading Chinese cabbage (the kind with green petioles in the Chinese cabbage subspecies common cabbage variety) have the advantages of high temperature resistance, they can realize continuous cultivation and increase yield, but they have slow growth rate and rough fiber. Many, poor taste defects, difficult to meet people's demand for heat-resistant good n...
