Breeding method for heatproof red-skin radish

Abstract

The invention discloses a heat-resistant red-skinned radish variety breeding method, which belongs to the technical field of cruciferous vegetable breeding. The technical feature of the present invention is that the red-skinned white-fleshed radish first-generation hybrids of heat-resistant summer planting are formed by using the red-skinned radish male sterile line as the female parent and the red-skinned high-generation inbred line as the male parent. A hybrid of red-skinned and white-fleshed radish planted in summer, the leaves of the plant are semi-recumbent, flat leaves, green leaves, red petioles and mid-ribs, bristles on the leaves, obovate leaf shape, tooth-shaped leaf margins, and a leaf length of about 30 cm. . The fleshy root is long and cylindrical, with smooth skin, red skin, and white flesh. The commercial root is 25‑30 cm long, 6‑7 cm in transverse diameter, and weighs about 500 grams per root. Strong heat resistance and disease resistance, good commerciality, high quality, not easy to bran heart, short growth period. It is suitable for outdoor cultivation in summer and autumn and autumn and winter.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a breeding method for heat-resistant red radish, which is specially used for [0002] The commercial fleshy root is the first-generation hybrid of long cylindrical heat-resistant radish with red skin and white flesh. Background technique [0003] Radish, also known as Lai Lu, belongs to the genus Brassicaceae and the genus Radish, an annual or perennial herb. As an important worldwide vegetable originating in my country, my country has a long history of cultivation and extremely rich variety resources. Radish production takes autumn as the main production season, and there are many varieties suitable for cultivation in autumn, and the corresponding cultivation measures are relatively perfect. When cultivating radish in summer, it is easy to encounter harsh natural conditions such as continuous high temperature, frequent storms, drought, pests and diseases, wh...
