CAO Ping
Abstract：In order to solve the problems of unstable yield and disease susceptibility in the cultivation of winter-spring flowering Chinese cabbage in Fuzhou,a field comparison test was carried out by using the local main cultivar Jinpin Lvfeng No.2(CK)as the control group.Then,the agronomic traits and yield of 47 new combinations of Chinese flowering cabbage were systematically evaluated.The randomized block design was used in the experiment,and the growth period,plant type,main stem traits and disease resistance were investigated.The results showed that:the yields of CX24449,CX24565 and CX24484 were 32 818.5,32 818.5 and 31 848.0 kg·hm-2,respectively,which were 18.4％-22.2％higher than that of the control Jinpin Lvfeng No.2.The yield increase reached a very significant level,with the advantages of strong main stem(3.1-3.4 cm)and high disease resistance.CX24439(29 013.1 kg·hm-2),CX24386(28 672.8 kg·hm-2)and CX24354(30 101.0 kg·hm-2)were outstanding in terms of commodity and stress resistance.By considering the indexes of yield,commodity and stress resistance,the four combinations of CX24449,CX24439,CX24386 and CX24354 with excellent comprehensive performance were preliminarily screened out,which were the optimization for the cultivation of winter-spring flowering Chinese cabbage varieties in Fuzhou area.
