Comparison of Different Cabbage Lettuce Cultivars in Greenhouse of Tianjin

We introduced ten cabbage lettuce cultivars from Japan and Korea in order to screen out the suitable cultivars to plant in the greenhouse of Tianjin, and the comparative trial was carried out by taking the randomized block design. And we analyzed the effects of the planting adaptability and commodity of the new planted cultivars on the yields and qualities of the cabbage lettuce cultivars in the greenhouse. The results of subordinate function analysis showed that the four cabbage lettuce cuhivars, Jiangjun, Huangdi, Dahu and Malaike, possessed better comprehensive characters than the control cultivar Kaisa, and they were more fit to be planted and extended in the greenhouse of Tianjin and neighborhood areas.
