| Flowering Chinese cabbage and Chinese kale are important leafy vegetables in Guangdong Province. They have the characteristics of large planting area, high multiple cropping index and large market demand. With high nutritional value and unique flavor, they have been indispensable vegetables in people’s daily diet. Guangdong Province is the main production area of flowering Chinese cabbage and Chinese kale in autumn and winter. With the expansion of planting areas in northern China in summer and consumers’ demand for the commodity and quality of leafy vegetables, new requirements have been put forward in the yield, adaptability, resistance and flavor content of existing varieties. Through the collection, preservation and excavation of germplasm resources, various scientific research units in Guangdong Province have carried out a large amount of breeding and molecular biology research work on flowering Chinese cabbage and Chinese kale, which has promoted the replacement of varieties from conventional species to hybrids, and also laid a foundation for molecular breeding in the future. However, there are still some problems in actual production of flowering Chinese cabbage and Chinese kale in Guangdong Province. It is necessary to make breakthroughs in the characteristics of the varieties themselves and the excavation of excellent germplasm resources, and use modern biotechnology to combine with conventional hybrid breeding techniques to improve the resistance, quality and adaptability of varieties. Therefore, this article reviews the research history, germplasm resource collection, molecular biology research and industrial development status of flowering Chinese cabbage and Chinese kale in Guangdong Province in order to provide references for the development of leafy vegetables in Guangdong Province. |
