Abstract:
The breeding of new varieties of Chinese cabbage is the guarantee for the efficient and sustainable development of Chinese cabbage industry. In order to select new varieties of Chinese cabbage with heat resistance, disease resistance and high yield to meet the market demand, 18 new combinations of Chinese cabbage which were selected and bred by Fujian Jinpin Agricultural Science and Technology Co., Ltd. were evaluated and tested, in order to analyze the correlation between the disease index of tipburn and agronomic traits in different new combinations of Chinese cabbage. The results showed that the disease index of tipburn of the new combinations of Chinese cabbage, including Q2047, Q2008 and Q2017 was 27.77-33.33, belonging to the disease-resistant combination. And there was no significant correlation between the disease index of tipburn and agronomic traits in 18 new combinations of Chinese cabbage. Compared with the agronomic traits of the control group Jinpin 535, the new combinations Q2017 and Q2047 showed outstanding performance in he resistance to tipburn and agronomic traits among the 18 new combinations, which could be recommended for the demonstration and promotion as the new good varieties of Chinese cabbage in summer and autumn in Fuzhou area.
