[0034] Comparison of rapid propagation technology and conventional method of green onion

[0035] The cultivation method of green onion rapid breeding, its feature is carried out according to the following steps:

[0036] Off-site cultivation: After confirming that the scallion seeds are harvested, immediately sow them in a cool area with a temperature of 10-25°C suitable for the growth of scallions to ensure the rapid vegetative growth of scallions; 90 days after sowing, the average stem diameter of scallions reaches 1-2cm, try to Use the natural environment of the local first frost period to achieve vernalization conditions. If it is treated at 0-5°C for 15 days, it will reach the reproductive growth conditions of scallions through vernalization, and transport the plants to areas with a temperature of 20-30°C for planting. , 30-40 days after planting, the scallions will bloom, and 60 days after planting, they will bear fruit; the entire growth period is within 6 months; the ...

[0041] Application of Rapid Breeding in Scallion CMS Breeding (2011.6—1012.6)

[0042] On May 11, 2011, after a sterile plant (no pollen itself) was found in the "Five-leaf Qi" scallions (Tianjin local variety, available in the national market) planted in the Vegetable Expo Garden in Xiqing District, Tianjin, the gauze screen was immediately removed. Isolate the plant (to avoid its natural pollination), and pull out the flower stamens that have already opened. The number of the green onion plant is w-1. Select its adjacent normal plant (with pollen) that has just opened and isolate it with gauze. It has opened before pulling out the isolation. After the pistil, the number f-1 was used as the male parent to cross with w-1, and f-1 was selfed at the same time; on June 2, 2011, 2 seeds were harvested: w-1×f-1 (a sterile plant The hybrid generation of w-1 and f-1) and f-2 (f-1 inbred); sowed in Guyuan on June 8, unearthed on June 13, the weather in Guyuan from June to September 20...

Abstract

The invention discloses a cultivation method for quickly breeding allium fistulosum. The cultivation method mainly comprises the steps that cultivation at different places is reasonably arranged, allium fistulosum seeds are sown at a cold area which is suitable for allium fistulosum growth at the seedling stage, it is guaranteed that the average stem diameter of the allium fistulosum can reach 1-2 cm after the allium fistulosum seeds are sown for about 90 days, the natural environment when the first frost date approaches at the local place is fully utilized, so that the allium fistulosum is subjected to vernalization smoothly, plants are transported to the area with the temperature being 20-30 DEG C for field planting, the plants can enter in a reproductive growth stage smoothly, the allium fistulosum blooms after field planting is conducted for 30-40 days, and fruitage can be achieved after 60 days; the first alternation of generations of the allium fistulosum can be completed within six months; afterwards, harvested seeds are sown continuously, the temperature is controlled within the range of 10-25 DEG C, it is guaranteed that the average stem diameter of the allium fistulosum can reach 1-2 cm after sowing is conducted for about 90 days, field planting is carried out in the natural environment at the early spring, sudden change of seasons and air temperatures is utilized ingeniously to enable the allium fistulosum to enter in the reproductive growth stage through vernalization, and fruitage is achieved after field planting is conducted for 60-80 days; the rapid two-generation breeding process of the allium fistulosum can be realized in one year. By means of the cultivation method for quickly breeding allium fistulosum, the breeding speed of the allium fistulosum can be greatly increased.

Description

technical field [0001] The invention belongs to the technical field of vegetable breeding and relates to the research on shortening the generation cycle of scallions, more specifically a cultivation method for rapid breeding of scallions. Background technique [0002] Scallions (Allium fistulosum L.) are native to China and are biennial herbaceous plants. Scallions are one of the most important vegetables in daily life. The planting area, total output and consumption of scallions in my country rank first in the world. Our country is rich in germplasm resources of scallions and has various forms. Since the breeding of hybrid scallions in my country started late, most of the domestic consumption is conventional varieties of farmers. Most of the scallion varieties imported from Japan into my country are hybrid varieties prepared by male sterile lines, and their hybrid advantages are obvious. my country is a large agricultural country, but the scallion breeding methods are far...
