Problems solved by technology

[0003] At present, the breeding of tartary buckwheat is still based on empirical breeding, the selection of hybrid offspring is blind, the method of planting offspring is subjective, the repetition of labor is high, and the success rate of breeding is low, which seriously restricts the production of tartary buckwheat and the increase of yield.

Embodiment 1

[0024] It is expected to obtain varieties with high yield per unit area, that is, the trait to be improved is yield. The local tartary buckwheat Xinong 9940 with low yield performance was selected as the female parent and the southern tartary buckwheat variety Jiujiang tartary buckwheat with high yield performance was selected as the male parent. The grain weight per plant is 4.26g, and the thousand-grain weight is 20.15g;

[0025] The specific selection method is as follows:

[0026] (1) Select Xinong 9940, a tartary buckwheat variety that needs to be improved, as the female parent, and Jiujiang tartary buckwheat as the male parent. The female parent and male parent are planted alternately, and artificially crossed to obtain F1 generation hybrid seeds. Select 10 F1 generation hybrid seeds ;

[0027] (2) The F1 generation hybrid seeds selected in step (1) were planted in a single hole, with a row spacing of 50 cm and a plant spacing of 20 cm, without single plant selection, ...

Embodiment 2

[0046] It is expected to obtain tartary buckwheat individual lines (variety) with black seed coat color, that is, the trait to be improved is seed coat color. Choose the light gray tartary buckwheat variety Xinong 9909 as the female parent and the black tartary buckwheat variety Xinong 9940 as the male parent. Among them, Xinong 9909 is medium-ripening, with green young stems, yellow-green flowers, no fragrance, and light gray grains; Xinong 9940 seedlings Vigorous growth, dark green leaves, heart-shaped leaves, white-green flowers, triangular grains, black grains;

[0047] Specific breed selection methods are as follows:

[0048] (1) Choose Xinong 9909, a gray tartary buckwheat variety whose seed coat color needs to be improved, as the female parent, and Xinong 9940, a black tartary buckwheat variety, as the male parent. The female and male parents are planted alternately, and artificially crossed to obtain F1 generation hybrid seeds. Select 10 F1 generation hybrid seeds;

...

Embodiment 3

[0059] It is expected to obtain individual strains (variety) of dwarf buckwheat, that is, the trait to be improved is plant height. The high-stalk local tartary buckwheat Xinong 9920 to be improved was selected as the female parent and the short-stem Chuanqiao No. 1 was selected as the male parent. Among them, Xinong 9920 has a compact plant type, a plant height of 110cm, green young stems, yellow-green flowers, and no fragrance. Self-pollination, grain taupe; Chuanqiao No. 1 is early maturing, plant height 90cm, green seedlings, turning purple when mature, compact plant type, green flowers, black grains;

[0060] Specific breed selection methods are as follows:

[0061] (1) Select the high-stem tartary buckwheat variety Xinong 9920 as the female parent, and the short-stem variety Chuanqiao No. 1 as the male parent. The male parent and the female parent are planted alternately and artificially crossed to obtain F1 generation hybrid seeds. Select 10 seeds F1 generation hybrid ...

Abstract

The invention provides a breeding method of the tartary buckwheat variety, wherein the variety with improved properties is selected as the female parent, and the variety complementary to the variety with improved properties as the male parent, the male parent and the female parent are planted in a staggered row planting way, and artificial hybridization is performed to obtain F1 generation hybridseeds, 10 or more F1 generation hybrid seeds are selected, and the F1 generation seeds are sown again, until the F9 seeds are selected, and then the F9 seeds are sown by row planting to finally obtaina stable tartary buckwheat variety. The breeding method of the tartary buckwheat variety provided by the invention has high success rate of variety breeding, can overcome defects of blind planting existing in the breeding process of the hybrid offspring of the tartary buckwheat variety, and can realize standardized management of the hybrid offspring of tartary buckwheat.

Description

technical field [0001] The invention belongs to the technical field of breeding of crop varieties, and in particular relates to a method for breeding of tartary buckwheat varieties. Background technique [0002] Tartary buckwheat is an important miscellaneous grain crop in my country. It is mainly distributed in the southwest region and the areas along the Great Wall. It has rich nutritional value and plays an important role in the national regional economic development, food and pharmaceutical processing. Increasing tartary buckwheat production is the fundamental way to ensure the healthy and orderly development of tartary buckwheat industry in our country. [0003] At present, the breeding of tartary buckwheat is still based on empirical breeding, the selection of hybrid offspring is blind, the method of planting offspring is subjective, the repetition of labor is high, and the success rate of breeding is low, which seriously restricts the production of tartary buckwheat a...
