Embodiment 1

[0034] Embodiment 1 Technical route of the present invention

[0035] For the technical route of the present invention, see figure 1 , which is:

[0036] 1) Collect onion resources, identify and classify the resources, and select male sterile lines and maintainer breeding parents with certain characteristics of the breeding objectives, and male parent lines with certain characteristics of the breeding objectives from the onion resources according to the breeding objectives breeding parent;

[0037] 2) Using the breeding parents of the sterile line and the maintainer line as the breeding material, select a pair of sterile plants and fertile plants from the offspring of the breeding material for artificial pollination and selection of fertility and traits, and select some of the traits that meet the breeding objectives. x for CMS and maintainer lines;

[0038] 3) Using the breeding parents of the male line as the breeding material, select and breed y male lines whose part tra...

[0046] Collection and Identification Classification of Embodiment 2 Onion Resources

[0047] Our unit started the onion breeding research work in 1998, and has collected 63 onion materials such as purple skin resources such as Zixing (three types), red hydrangea (three types), Xinyou red flat pile, Gansu purple skin (four types), Red Sun (three types), Purple Star, Gao Yuan (three types), Taishan Purple Crown, Taishan Purple Jade, Purple Ball, Red Jade, Sun Purple, Xingda Purple Crown, Ziyun Xiuyu , Aichi Chiyu, Beidaohong, Xiongyue No. 2, etc.; yellow-skinned resources such as Chengde Huangyu onion (three types), Tianjin Dashuitao (four types), Tianjin water chestnut flat (three types), Xiongyue onion ( Three types), Beijing yellow skin (two types), etc.; white skin resources include Dingzhou white skin (four types), Baijingang, Baixue, Baiyan, Tianjin Xuanhuai (three types), etc.; imported foreign resources Cowboy, Pandora, Tokyo Daikadama, Hongbao 901, Hongshi, Hongdi, etc...

Embodiment 3

[0049] The breeding of embodiment 3 onion male sterile line and maintainer line

[0050] 1. Breeding of sterile plants

[0051] Male sterile genes are more commonly found in onions, and it is easier to find male sterile plants in the field. At about 10:00 am on a sunny day, touch the flower ball of the onion in full bloom with the palm of your hand. If there is no yellow pollen in the palm, it may be a male sterile plant, and then visually inspect the characteristics of the stamens and anthers.

[0052] The stamen filaments of male sterile plants are shorter, the anthers are smaller, and the anthers are greenish-yellow, yellowish-brown or grayish-yellow, and have no inclusions in Yangon perspective. Divided into three types: regular drug type, thin drug type and short stamen type. The characteristics of the anthers of the common drug type are similar to those of the fertile ones, but the color of the anthers is green and difficult to identify. Breed thin drug type and short...

Abstract

The invention discloses a method for breeding early-maturing high-yield storability half-height purplish-red-skinned onions. The method comprises the following specific steps of: collecting onion resources, identifying, classifying, and selecting sterile and maintainer line breeding parents I with certain characteristics of target varieties and male breeding parents with certain characteristics of target varieties; breeding paired sterile and maintainer lines with a part of characteristics of target varieties from sterile and maintainer breeding parents I which serve as breeding materials by culturing big female parents and female breeding parents; breeding male parent lines V with a part of characteristics of target varieties from male breeding parents which serve as breeding materials; pollinating artificially, hybridizing one female breeding parent with multiple male breeding parents to produce a plurality of hybrids, and selecting novel hybrid varieties having high male and female parent combination ability and having characteristics of target varieties. The onions bred by adopting the method are called Zikui No.3 and have purplish-red skins, half height, are high in yield, good in early maturity, short in growth period and good in storage resistance.

Description

technical field [0001] The invention relates to breeding technology, in particular to a method for breeding early-maturity, high-yield, storage-resistant half-height purple-skinned onions. Background technique [0002] Onion is a health-care vegetable with therapeutic value and rich nutrition, known as the 'Queen of Vegetables', especially in reducing blood fat, preventing vascular sclerosis and hypertension, anti-diabetes, anti-cancer, anti-aging, etc. Recognize and accept. Onion is a worldwide vegetable, and its production area ranks third (potato first, tomato second). According to the statistics of the Food and Agriculture Organization of the United Nations, the world's onion planting area is 3.0695 million hectares, and the output is 53.433 million tons. my country's onion planting area and output both rank first in the world, accounting for nearly 1 / 3 of the world's planting area and output. In recent years, through market research and research, analysis, and discus...
