Embodiment 1

[0023] One, the breeding method of the scallion germplasm of the low pungentness provided by the present embodiment and the tight pseudostem specifically comprises the following steps:

[0024] 1) Parent selection: In the extensive introduction experiment, the soluble solid content and pyruvate content of the introduced scallion varieties were measured as breeding indicators to represent the degree of sweetness and spiciness respectively. The mass fraction of soluble solids in Shandong local scallion "Yexuan No. 1 scallion" is 11.4%, and the content of pyruvic acid is 0.016 mg / g FW; the mass fraction of soluble solids in "Tokyo Xiahei" imported from Japan is 8.3% , the content of pyruvate was 0.07 mg / g FW.

[0025] 2) Artificial hybridization: use the Yexuan No. 1 (commercially available variety) scallion as the female parent, and the above-mentioned Tokyo Xiahei (commercially available variety) as the male parent to obtain Yexuan No. 1 scallion x Tokyo Xiahei F1 generation m...

Embodiment 2

[0044] The breeding method of the scallion germplasm with low spicy taste and tight pseudostem provided by the present embodiment specifically comprises the following steps:

[0045] 1. Parental selection: The soluble solid content of Shandong local green onion "Zhangqiu green onion" is 13.9%, and the content of pyruvic acid is 0.009mg / g FW; the soluble solid content of Japanese imported green onion "Jukuni Ihontai" is 8.8%. The pyruvate content was 0.078 mg / g FW. The determination of soluble solids content, pyruvic acid content and pseudostem compactness is the same as in Example 1.

[0046] 2. Artificial hybridization: use the Zhangqiu scallion (commercially available variety) as the female parent, and use the above-mentioned Shiguo Ippentai (commercially available variety) as the male parent to obtain Zhangqiu scallion × Shiguoibentai F1 Generation hybrids.

[0047]3. Self-breeding of F1 generation: Sow the Zhangqiu scallion × Shiguo Intai F1 generation hybrid seeds harve...

Abstract

The invention provides a method for breeding green onion germplasm with low spicy taste and tight pseudostem. The breeding method comprises parental selection, artificial hybridization, selfing of F1 generation, precise selection of F2 generation and continuous selfing of F3 to F5 generation Identification. According to the parent selection of the present invention, the soluble solids content and pyruvic acid content represent the degree of sweetness and spicy taste respectively, and a new species of green onion with tight pseudostem and lighter spicy taste can be bred through the technical scheme of the present invention. Quality, has a good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a method for breeding green onion germplasm with low spicy taste and tight pseudostem. Background technique [0002] green onions ( Allium fistulosum L. var. giganteum Makino) is a biennial or perennial herbaceous plant of the Allium family Allium genus, which originated in North China and is now widely cultivated in China, Japan, Korea and South Korea. Because scallions are rich in nutrients, especially contain special sulfides, they can be eaten raw or cooked, and are important condiments in my country. Green onions also have medical effects such as stimulating sweating, stimulating digestion, and killing various germs, which are deeply loved by the people. [0003] The spiciness of scallions varies from variety to variety. The sweeter scallions on the market are suitable for raw food, while the hotter scallions are more suitable for cooked food. Gener...
