Problems solved by technology

Domestic and foreign breeding methods are based on the respective advantages of resistance and traits of the same kind of radish, cross-breeding super-parent varieties, but due to the constraints of kinship, heterosis can only be limited to a certain range, and under natural conditions, affinity Low sex and hybridization rate, low breeding yield

Embodiment

[0014] Step 1. Purchase the main varieties in the main production areas in the market. Wuhan Yafei Seeds distributes the mosaic radish varieties "Dahao", "TI-084", "Zengshui" and "Sanchuan Dagen" selected by Asahi Farm in Japan. The mosaic radish variety "Fulinmen" and the seedling "Baiyuchun" selected by Korea Daeong Seedling Co., Ltd. Trial planting of the variety was planted on August 20, and the purity, yield, quality, and incidence of mosaic virus disease were tested on November 25. The test results show that the purity of the 6 imported radish varieties is up to 99%; the weight of each root is 0.75-1.45Kg; in terms of quality, only "TI-084" has a sugar content of 3.8%, which cannot meet the high-quality standard and cannot be used as a female parent for breeding ; In terms of the incidence rate of mosaic virus disease, the incidence rate is 15-28%, and all 6 varieties are susceptible to the disease. On April 15, when the sterility rate was in full bloom, the results sho...

Abstract

The invention relates to a method of breeding hybrid seeds of vegetables, particularly relates to a method utilizing hybrid advantages between two types of radishes, and belongs to the technical field of vegetable hybrid breeding. The method comprises the steps of selecting high-yield and high-quality petal-leaf radish as a female parent and mosaic virus disease-resistant and heat-resistant broad-leaf radish as a male parent; carrying out hybridization of the broad-leaf radish and the petal-leaf radish to obtain an intermediate type radish combination; and selecting the radish species with good compatibility, obvious hybrid advantages, high yield, high quality and good resistance to popularize and apply.

Description

technical field [0001] The invention relates to a method for cultivating hybrids of vegetables, in particular to a method for utilizing hybridization advantages between two types of radishes, and belongs to the technical field of vegetable hybrid breeding. Background technique [0002] Radish (Raphanus sativus L) is a one-year or two-year root vegetable of the genus Radish in the Brassicaceae family. The annual planting area is about 1.2 million hm2, and it is the second largest vegetable after Chinese cabbage. my country is the origin of radish, and its germplasm resources are very rich. In the south, the high-temperature and rainy evaporation has a large amount of evaporation, and the disease-resistant and heat-resistant flat-leaf radish varieties are the main varieties. host. Through the efforts of several generations of breeders, significant achievements have been made in resource utilization and innovation. New radish varieties have been selected from conventional breed...
