Problems solved by technology

Guizhou Province has abundant rainfall, but due to uneven rainfall, the soil water retention capacity in karst mountainous areas is poor, which threatens the production of coix coix in varying degrees in spring drought and summer drought. Drought has become one of the main factors restricting the production of coix coix in Guizhou

Embodiment 1

[0025] A method for breeding drought-resistant Coix varieties, comprising the following steps:

[0026] 1. Select 50 uniform and plump seeds from the variety of Coix to be tested, and use 0.1% HgCl 2 Disinfect for 8 minutes, then rinse 5 times with distilled water;

[0027] 2. Dry the seeds in step 1 with filter paper, soak them in -0.1MPa PEG-6000 aqueous solution for 24 hours, and then place them in a germination box with a length of 24 cm, a width of 24 cm, and a height of 12 cm and covered with 3 layers of filter paper. The distance between seeds is 1.5 times of the grain length, add 15mL-0.1MPa PEG-6000 aqueous solution into the germination box, then put the germination box in the RXZ-1000B artificial climate box, set the day / night temperature to 28°C / 25°C , the humidity is 85%, the light / darkness is 12h / 12h, and the light intensity is 340μmol / (m 2 s), continuously cultivated for 10 days, supplemented with appropriate amount of distilled water every 2 days, to keep the ...

Abstract

The invention discloses a breeding method for a drought-resisting semen coicis variety, and belongs to the technical field of new crop variety breeding. The method comprises the following steps of semen coicis variety germination stage drought resistance authentication, semen coicis variety seedling stage drought resistance authentication and semen coicis variety adult-plant stage drought resistance authentication. The drought resistances of the semen coicis variety germination stage, seedling stage and adult-plant stage are comprehensively assessed, and the bred semen coicis variety has the excellent drought resistance, has the advantages of high yield and good quality and can adapt to the hydropenic growth condition of the karst mountainous area.

Description

technical field [0001] The invention relates to the technical field of breeding new varieties of crops, in particular to a method for breeding drought-resistant coix varieties. Background technique [0002] Job's tears is an annual herb of the Poaceae Coix genus. It is a traditional medicinal and edible economic crop. Because of its high nutritional value and important medicinal value, it is more and more popular among people. The main edible and medicinal part of Coix is ​​the seed kernel, which is a green food with high protein, medium fat and medium sugar. s King". China is a big producer of coix, and the main production areas are concentrated in the southwest and south China. Coix is ​​one of the main characteristic miscellaneous grain crops in Guizhou. Its planting area and output rank first in the country. It plays an important role in the adjustment of planting industry structure and industrial development in Guizhou. Substitute role, among them, Xingren County is t...
