Problems solved by technology

Green stalks (the kind with green petioles in common cabbage varieties) are not easy to bolt, so the cultivation time of green stalks for stalks in a year is relatively short. Generally, they are only planted in winter

[0029] 1. Breeding of female parent Pleurotus chinensis Select 36 high-generation parental materials of Pleurotus chinensis (Table 1) and sow on November 25, 2016, investigate the morning and evening of bolting and flowering in early spring, and measure the affinity index. At the same time, investigate plant traits, Disease resistance, etc., screened out 3 self-incompatible lines (Q-4-14, S22, Q-30 -3).

Abstract

The invention provides a method for breeding bolting green-stem vegetables, and relates to the technical field of breeding new varieties. According to the method described in the invention, an early-bolting high-quality green-stem vegetable material is screened out from a large number of materials, and is hybridized with an early-maturing cabbage heart material with good disease resistance to breed an early-maturing high-quality bolting green-stem vegetable variety required by the market. The characteristics of flowering without vernalization of the cabbage heart material is used to perform hybridizing with the green-stem vegetable easy-bolting parent material, the easy-bolting characteristic of the early-maturing cabbage heart material is transferred to the green-stem vegetable, and an early-maturing, heat-resistant, high-quality and disease-resistant bolting green-stem vegetable new variety which can perform bolting in summer and autumn is bred. The method of the invention can enrichtypes of green-stem vegetables, and breeds early-maturing high-quality bolting green-stem vegetable new varieties to meet market demands.

Description

technical field [0001] The invention belongs to the technical field of new variety selection and breeding, and in particular relates to a method for breeding green stem vegetables for stalks. Background technique [0002] Cabbage sprouts (cai xin) are a variety of Brassica cabbage subspecies in the family Brassicaceae. They use the young flower sprouts as edible organs. It is one of the unique vegetable species in my country. The area is getting bigger and bigger. Cabbage sprouts originated in the Yangtze River Basin and are one of the important vegetable varieties in autumn and winter. They are cultivated all over the country, especially in Hunan, Hubei, Anhui, Jiangsu, Zhejiang, Jiangxi and other places. Green stalks (the kind with green petioles in common cabbage varieties) are not easy to bolt, so the cultivation time of green stalks for stalks in a year is relatively short. Generally, they are only planted in winter and spring bolting, and there are few special varietie...
