Abstract

The invention relates to a breeding method of hybrid cabbage, in particular to a simplified breeding method for preparing hybrid cabbage by using cytoplasmic male sterile lines, which belongs to the technical field of plant culture. The invention directly adopts the cabbage varieties of Zhonggan No.22 and Hugan No.2 prepared by cytoplasmic male sterile lines sold in the market as maternal plants, and adopts cabbage inbred lines (with the same ball shape as the maternal plants, the same type of leaf ball mature performance as the maternal plants and stable botanical characters) as pollen suppliers for preparing good coenospecies. The invention has the advantages that when the advantages of using the cytoplasmic male sterile lines for preparing the cabbage coenospecies are maintained, good cabbage inbred lines do not need to be used as recurrent parents for fifth to seventh generation backcrossing and transformation with male sterilant materials, the labor is saved, the cost is saved, the breeding time is greatly shortened, and in addition, the hybrid vigour parts of the original varieties can be maintained into the new hybrid varieties.

Description

technical field

[0001] The invention relates to a breeding method of hybrid cabbage, in particular to a simplified breeding method for preparing hybrid cabbage by using a cytoplasmic male sterile line, and belongs to the technical field of plant cultivation. Background technique

[0002] Cabbage (Brassica oleracea var. capitata L.) is the main vegetable crop in China and many countries in the world. Because of its obvious heterosis, heterosis breeding has become the main way of cabbage breeding. At present, the excellent cabbage varieties used in production are almost all the first-generation hybrids, and there are two main ways to produce the first-generation hybrids of cabbage, that is, using self-incompatible lines to produce seeds and using male sterile lines to produce seeds. Seed production using self-incompatible lines has long been the main method for preparing the first generation of hybrids in cabbage. Great achievements have been made through this approach, and a ...
