筛选适合冷凉灌区秋季气候条件栽培的娃娃菜品种，为当地增产增收奠定基础。在甘肃省高原夏菜主产地兰州市榆中县开展了娃娃菜品种适应性研究，以当地主栽品种秋玉黄为对照，对引进的7个娃娃菜优良品种的产量和品质等性状进行测定，并进行隶属函数分析。结果表明，供试品种皇妃和金皇后的综合表现优于其他品种，2个品种的心叶均呈鲜黄色，叶球紧实，无干烧心，生育期较短(85 d)；其中，皇妃单株毛重2.06 kg、单株净重1.40 kg、经济产量86.1 t/hm2、Vc含量2.305 g/kg，均为最高，生物产量、净菜率、可溶性糖和可溶性蛋白含量较高，硝酸盐含量较低；金皇后净菜率为68.4%、可溶性蛋白含量为2.703 g/kg，均达最高，生物产量、经济量、单株毛重、单株净重、可溶性糖和Vc含量较高，硝酸盐含量较低。综合分析表明，皇妃和金皇后适合在甘肃省冷凉灌区秋茬推广种植。

In order to introduce mini Chinese cabbage varieties suitable for autumn climate conditions in Cold-cool irrigation areas of Gansu Province, the adaptability of mini Chinese cabbage varieties was studied in Yuzhong County, Lanzhou City, the main producing area of plateau summer vegetables in Gansu Province. Using the local dominantvariety Qiuyuhuang as the control, 7 introduced mini Chinese cabbage varieties were assessed for yield and quality parameters, followed by membership function analysis. Results showed that the comprehensive performance of Huangfei and Jinhuanghou was better than that of other varieties. The heart leaves of the two varieties were bright yellow, the head was tight with no dry heartburn detected, and the growth period was short (85 d). The single plant gross weight (2.06 kg), net weight (1.40 kg), economic yield (86.1 t/ha) and Vc content (2.305 g/kg) were the highest, the yield, fresh-cut vegetable rate, soluble sugar and soluble protein content were higher, and the nitrate content was lower in Huangfei. The net vegetable rate (68.4%) and soluble protein content (2.703 g/kg) of Jinhuanghou were the highest, the biological yield, economic yield, gross weight per plant, net weight per plant, soluble sugar and Vc content were higher, and the nitrate content was lower. The comprehensive analysis showed that the Huangfei and Jinhuanghou were suitable for autumn cropping in Cold-cool irrigation area of Gansu.
