Problems solved by technology

In recent years, new varieties of scallions resistant to bolting from Japan and South Korea have been introduced into my country. Compared with domestic scallions, they have many advantages such as bolting resistance, strong resistance, and lodging resistance. The cultivated area is increasing year by year, but there are the following Outstanding problems: 1. Expensive seeds, high planting costs; 2. High cellulose content, poor fresh food quality; 3. Poor low temperature resistance, unable to survive winter in cold regions
The entire identification cycle takes about 400 days, which seriously delays the bolting-resistant breeding process of scallions
[0005] 2. Bolting...

Embodiment 1

[0060] When scallion seedlings encounter suitable low temperature, immature bolting will occur, seriously reducing their commerciality. The best way to solve this problem is to breed scallions resistant to bolting. The method for rapid evaluation and classification of scallion resource materials for bolting is a breeding process. key means in. After three consecutive years of experimental research and verification in 2017, 2018, and 2019, including seedling age, vernalization and bolting environmental conditions, screening of bolting indicators, and verification of natural vernalization and bolting in the field, the scientific nature of the method has been fully confirmed. Accuracy and practicability can be widely used in the identification and evaluation of bolting properties of green onion resource materials, and accelerate the breeding process of green onion. Now with examples:

[0061] Step 1: Select 19 parts of scallion seeds and store them in a refrigerator at 0-4°C;

Abstract

The invention discloses a rapid allium fistulosum bolting evaluation and classification method which comprises the following steps: 1, preserving allium fistulosum material seeds to be identified in arefrigerator; 2, selecting mature and full seeds, and performing seeding; 3, performing transplanting, namely after seeding, transplanting allium fistulosum seedlings with 3 true leaves into a cultivation tank; 4, putting the cultivation tank into a manual climatic box, and performing low-temperature vernalization; 5, performing bolting and flowering management; and 6, investigating bolting indexes, and performing bolting evaluation. The method has the advantages that a conventional allium fistulosum bolting identification and evaluation cycle is shortened, and the allium fistulosum bolting breeding progress can be accelerated. Limits of natural environments are avoided, the operation feasibility is high, bolting identification and evaluating grading is clear, and the accuracy rate is high.

Description

technical field [0001] The invention relates to the technical field of plant breeding and selection, in particular to a method for rapid evaluation and classification of bolting properties of green onions. Background technique [0002] Scallion (Allium fistulosum L.var.giganteum Makino) belongs to Allium family Allium, 2 years old or perennial. It is a typical green body vernalized vegetable crop. Only after bolting and flowering. In the northern production areas of my country, if the variety is not properly selected, the seedlings encounter low temperature, and the immature bolting and flowering will seriously reduce the quality of green onions. In recent years, new varieties of scallions resistant to bolting from Japan and South Korea have been introduced into my country. Compared with domestic scallions, they have many advantages such as bolting resistance, strong resistance, and lodging resistance. The cultivated area is increasing year by year, but there are the follow...
