Problems solved by technology

[0003] In the prior art, the γ-linolenic acid content of the cultivated borage is low, only about 15-20%, the protein content is about 10%, the fat content is about 20%, and the linoleic acid content is only 6-8%. %, due to its low content of nutrient elements, its performance in various aspects is also poor, and it cannot achieve the desired medicinal effect

Embodiment 1

[0024] The selection and cultivation methods of borage are as follows:

[0025] 1) Select the traits of the parent: the growth period is 121 days, the leaf base is whorled, oblong, the petiole and veins have white fluff, and the leaf surface has irregular cell patterns. Infinite inflorescences, drooping, pedicels usually purple; petals are pink in buds, purple after flowering, 5 petals, 5 stamens, arranged in a conical shape in the center of the flower, 12-15 flowers per branch. The grain is oval, gray-black, with a protein content of 15%, a fat content of 25%, and an ash content of 8%. The grain contains unsaturated palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid and arachidic acid acid, the content of linoleic acid reaches 10%, and the content of gamma-linolenic acid is 18%;

[0026]2) Use the above-mentioned excellent strains as parents to carry out generation selection and breeding for 6 generations to obtain borage. There are irregular cell patter...

Abstract

The invention provides a borage breeding method. The borage breeding selection method includes the steps of performing generation selection of 6-8 generations of good strains, by mass percentage, 18%-24% of gamma-linolenic acid, 15%-20% of protein, 20%-25% of fat and 10%-12% of linolenic acid as parents to obtain borage. The embodiment of the invention also provides a borage cultivation method. The borage cultivation method includes the steps of selecting environmental conditions of the total annual sunshine hours of 2802h-2964.7h, the total annual solar radiation amount of 136 kcal / cm<2>-143 kcal / cm<2>, the annual average temperature of 1 DEG C-6.5 DEG C and the diurnal temperature of 13.3 DEG C-17.7 DEG C; performing tillage and soiling preparation, sowing, performing fertilization and irrigation and harvesting when borage matures. The obtained borage is high in nutrients content, medicinal value and yield, can achieve extensive cultivation and is high in industrialization level.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a method for breeding and cultivating borage. Background technique [0002] Borage is an annual herb belonging to the Boraginaceae family, with a slight cucumber fragrance. Plant height 60 cm (2 feet), covered with coarse hairs. The leaves are large, rough, oblong, and the inflorescences are loose and drooping; the pedicel is usually light red; the flowers are star-shaped, bright blue, sometimes white or rose; the stamens are bright yellow, 5, arranged in a conical shape in the center of the flower. It is native to the eastern Mediterranean coast and Asia Minor, and is now widely cultivated in Europe and North America. It can be used as a nectar source plant. The fresh leaves are used as vegetables in Europe, and the fresh and dried leaves can be used for seasoning stews, soups, and beverages. It is rarely planted in China. Because its seeds are rich in protein, fat, iron and other...
