Embodiment 1

[0038] Taking the incubator and field test conditions with automatic temperature control, humidity control, light control and ventilation conditions as an example, the incubator is used for seedling screening, and the field is used for hybridization, selfing, homozygosity and screening.

[0039] Follow these steps:

[0040] A. Material hybridization stage:

[0041] A1) Select Puyi No. 6, a variety recognized in Fujian Province, as the female parent, and wild Coix as the male parent;

[0042] A2) Arrange the sowing period according to the growth period of the Coix variety, so that the two Coix varieties bloom at a similar time (that is, the interval between the flowering time of the two Coix varieties is less than 7 days);

[0043] A3) After flowering, remove the stamens from the variety used as the female parent;

[0044] A4) free hybridization;

[0045] A5) Harvest seeds separately from father and mother;

[0046] A6) Dried and stored;

[0047] A7) In the second year, pl...

[0069] Taking the incubator and field test conditions with automatic temperature control, humidity control, light control and ventilation conditions as an example, the incubator is used for seedling screening, and the field is used for hybridization, selfing, homozygosity and screening.

[0070] Follow these steps:

[0071] A. Material hybridization stage:

[0072] A1) Select Ningyi No. 1, a variety recognized in Fujian Province, as the female parent, and wild Coix as the male parent;

[0073]A2) Arrange the sowing period according to the growth period of the Coix variety, so that the two Coix varieties bloom at a similar time (that is, the interval between the flowering time of the two Coix varieties is less than 7 days);

[0074] A3) After flowering, remove the stamens from the variety used as the female parent;

[0075] A4) free hybridization;

[0076] A5) Harvest seeds separately from father and mother;

[0078] A7) In the second year, p...

Embodiment 3

[0100] Taking the incubator and field test conditions with automatic temperature control, humidity control, light control and ventilation conditions as an example, the incubator is used for seedling screening, and the field is used for hybridization, selfing, homozygosity and screening.

[0101] Follow these steps:

[0102] A. Material hybridization stage:

[0103] A1) Choose Xianyi No. 1 as the female parent, and wild coix as the male parent;

[0104] A2) Arrange the sowing period according to the growth period of the Coix variety, so that the two Coix varieties bloom at a similar time (that is, the interval between the flowering time of the two Coix varieties is less than 7 days);

[0105] A3) After flowering, remove the stamens from the variety used as the female parent;

[0106] A4) free hybridization;

[0107] A5) Harvest seeds separately from father and mother;

[0108] A6) Dried and stored;

[0109] A7) In the second year, plant the F1 coix seeds harvested from the...

Abstract

The invention discloses a method for selecting and breeding a selenium-rich semen coicis variety and belongs to the field of semen coicis variety selection and breeding. According to the method, by utilizing the characteristic of high heterozygosity caused by cross pollination of semen coicis, after natural crossing of semen coicis with different varieties, in the seed germination stage and the seedling stage, selenium-rich specific plants are screened by treating the plants with a special chemical agent, self-bred homozygosis is carried out through bagging (or isolation), and selenium enrichment directed screening is continuously carried out in the seedling stage, and the selenium-rich semen coicis variety with stable phytological shape, unified trait and considerable yield is obtained. The method shortens the selecting and breeding time of the semen coicis variety, improves the selecting and breeding efficiency of the selenium-rich semen coicis variety and provides an efficient and reliable way to selection and breeding of the selenium-rich semen coicis variety.

Description

technical field [0001] The invention belongs to the field of coix variety breeding, and in particular relates to a selenium-enriched coix variety breeding method. Background technique [0002] Selenium is an essential trace element for the human body. It plays a significant role in improving human immune function, enhancing anti-cancer ability and preventing cardiovascular diseases. It is known as the "king of anti-cancer and anti-cancer" by scientists. China is internationally recognized as a major selenium-deficient country. The soil selenium-deficient area accounts for about 2 / 3 of the country's land area. Soil selenium deficiency restricts the selenium nutritional status of food. According to the survey of the Chinese Nutrition Society, the daily selenium intake of adults in my country is only 26.63Lg, which is far from the daily intake of 50Lg and 60Lg recommended by the Chinese Nutrition Society and the International Selenium Society. To meet the normal needs of the hu...
