In view of the advantages and disadvantages of green leafy vegetables, we carried out a study on the heat resistance improvement of non-heading Chinese cabbage. In order to explore the heat-resistant mechanism of non-heading Chinese cabbage, find a simple and sensitive identification screening method and create heat-resistant germplasm for many years Experimental research, this article reports some of the results. 1 Materials and Methods The tetraploid cultivars provided by Horticultural Institute of Shanghai Academy of Agricultural Sciences and tetraploid cultivars provided by Nanjing Agricultural University Department of Horticulture were used as materials for the test, seeds were cultivated under aseptic conditions, and the germinated seeds were compared with each other rate
