Embodiment approach

[0013] 1. The implementation of a method for improving the hybridization efficiency of self-incompatibility Utah cabbage: In recent years, we have rationally combined self-incompatibility Utah cabbage for pre-hybridization, generally with September-October Carry out seedling cultivation, when the seedlings are planted at the 4-6 leaf stage, two self-incompatibility Utah plants that will be prepared for hybridization will be planted together with a distance of 20cm during planting, and should be shed with other cruciferous plants. room or distance isolation. Insert bamboo pole supports around the two plants of Wutai before they bloom in March of the next year, and use an insect-proof net of 80cm*100cm size above 60 mesh to cover the two plants of Wutaia downwards, and cover the bag mouth with soil at the bottom Seal it tightly to prevent insects from entering and leaving. After flowering, shake the insect-proof net bag regularly during the flowering period to promote the spread...

Abstract

The invention discloses a method for improving the hybridization efficiency of wutah, which belongs to the field of horticultural technology. It mainly aims at the labor-intensive, time-consuming and low-efficiency characteristics of artificial hybridization of Wutaicai, and improves the hybridization efficiency of Wutaicai through isolation, reasonable assembly, bagging, and removal of shriveled seeds. The invention has the characteristics of simple operation, low cost, good effect and the like.

Description

technical field [0001] The invention relates to a method for improving the hybridization efficiency of self-incompatibility Utah cabbage, which belongs to the field of horticultural technology. Background technique [0002] Wutaicai is a variant of the subspecies of Brassica Brassica in the family Brassicaceae. It is native to my country and is mainly distributed in the Yangtze River and Huaihe River basins. recorded. Wutaicai is more commonly cultivated in the middle and lower reaches of the Yangtze River, and can be produced year-round and supplied in four seasons. Wuta cabbage has strong cold resistance and is not afraid of frost. It can survive the winter in the open field along the Huaihe River. After frost and snow, its texture is softer, with very little fiber, delicious taste and better quality. It is regarded as the top grade of cabbage. It has the reputation of "the mutton with black vegetables in the twelfth lunar month". According to the measurement, the edible...
