Problems solved by technology

[0003] Generally, the content of erucic acid in the total fatty acid content of radish varieties for oil is between 25% and 45%, which is not conducive to human body absorption.
Yunnan wild oil radish variety "Mayahua" grows in high mountain areas at an altitude of about 1800. Its plants are short and its resistance is poor, so it is not suitable for promotion in plain areas and southern areas. However, its erucic acid content is less than 5%, which is an excellent breeding material

Embodiment Construction

[0016] Below in conjunction with embodiment, the present invention will be further described.

[0017] The breeding method and breeding pedigree diagram of this embodiment are shown in figure 1 .

[0018] In March 2006, the female parent wild species low erucic acid oil radish variety "Mayahua" (purchased from Kunming Vegetable Seed Company, Yunnan Province) and the male parent high yield, high erucic acid and strong resistance oil radish variety " "Red Danzi" (Shandan County Fumin Seed Co., Ltd., Zhangye City, Gansu Province) was cultivated in a greenhouse nursery, ensuring that the temperature of the seedbed at the seedling stage was not higher than 20°C and not lower than 5°C. The two varieties were removed from the nursery at the end of April. Planted in a breeding isolation greenhouse, the cultivation method is in accordance with the female parent: the male parent's row ratio of 1:1, and the cultivation is carried out in pairs, and the impurities are removed according to...

Abstract

The invention belongs to the technical field of breeding of plants for oil and relates to a breeding method of radishes with low erucic acid and high oil yield. The breeding method comprises the following steps: (1) taking sprout flowers of low-erucic-acid oil radishes with the erucic acid content of being less than 5% as female parents and taking high-yield, high-resistance and high-erucic-acid oil red ball-shaped radishes with the erucic acid content of being more than 30% as male parents; peeling off buds of the female parent sprout flowers at a flowering phase to remove stamens and pollinating pollen of the male parent red ball-shaped radishes; hybridizing to obtain F1; (2) planting the F1 one by one and carrying out strict selfing to obtain F2; (3) testing the content of the erucic acid of each F2 single-plant seed by using a gas chromatograph; selecting F2 strains with the erucic acid content of being less than 10% and good agronomic traits and remaining seeds, and weeding out the others; and (4) repeating the steps (2) and (3) and carrying out a plurality of generations of selfing and selection to obtain oil radish Fulai01 with low erucic acid, high yield, strong resistance and good properties, wherein the preservation number is CCTCC NO:P201603. Compared with a previous variety, the content of the erucic acid in the variety is reduced by more than or equal to 80%.

Description

technical field [0001] The invention belongs to the technical field of plant breeding for oil, and in particular relates to a method for breeding radish for oil with low erucic acid and high yield. Background technique [0002] Oilseed radish (Oilseed Radish) belongs to the genus Raphanus raphanistrum L.sp of Cruciferae. It is very different from ordinary cultivated radish. Oilseed radish is an annual herb with thin and weak taproots, not fleshy hypertrophy, and early flowering period. Seed yield is low. [0003] Generally, the content of erucic acid in the total amount of fatty acids of radish varieties for oil is between 25% and 45%, which is not conducive to human body absorption. Yunnan wild oil radish variety "Mayahua" grows in high mountain areas at an altitude of about 1800. Its plants are short and its resistance is poor, so it is not suitable for promotion in plain areas and southern areas. However, its erucic acid content is less than 5%, which is an excellent br...
