摘要

In order to screen out bolting-tolerant Chinese cabbage cultivars in Guiyang in winter and spring, we carried out a comparative test of eight Chinese cabbage cultivars or combinations in the open field in winter and spring. The results showed that, Qianbai No.5 had outstanding comprehensive characters, such as early harvest time, good tightness, high yield, good tolerance to cold and bolting, strong resistance to diseases, and combination BZ1×C-2 also had excellent comprehensive characters, such as vigorous growth, dark green leaf, good tightness, high yield, good tolerance to cold and bolting, strong resistance to diseases, high compactness and net yield rate, good tolerance to cold and bolting, and strong resistance to diseases. So, they were suitable for extension of cultivation in Guiyang area as well as in the places with similar climate in winter and spring. Furthermore, Qianbai No.5 was adaptable to be sold in areas where people preferred Chinese cabbage with light yellow heart leaves, while combination BZ1×C-2 was adaptable to be sold in areas where people preferred Chinese cabbage with green heart leaves.%为筛选出适合在贵阳等地冬春反季节栽培的优良耐抽薹新品种，对8个大白菜品种（组合）进行露地冬春季田间比较试验。试验结果表明，黔白5号采收期早，紧实度好，产量高，耐低温、耐抽薹性好，抗病性强，综合性状优；组合 BZ1×C－2生长势强，叶色深绿，紧实度、净菜率高，耐低温、耐抽薹性强，抗病性好，综合性状优，2个品种适宜贵阳及气候相似地区冬春季种植推广，其中，黔白5号适宜喜食浅黄心大白菜的地区销售，组合 BZ1×C－2适宜喜食绿心大白菜的地区销售。
