对８个大白菜品种，其中６个来自亚洲蔬菜研究发展中心（ＡＶＲＤＣ），２个来自天津，在天津市蔬菜研究所进行了品比试验。试验从１９９７年７月１０日开始，９月２０日结束。８个品种在耐热性、产量和园艺性状等方面均表现出显著差异。其中＃６２、＃８５－２０２和津白４５在高产性、早熟性和耐热性方面表现最为突出，是值得在天津地区夏季推广应用的耐热大白菜优良品种。
Of the eight Chinese cabbage cultivars, six were from the Asian Vegetable Research and Development Center (AVRDC), two from Tianjin and a ratio test was conducted at the Tianjin Vegetable Research Institute. The trial began on July 10, 1997 and ended on September 20. Eight varieties showed significant differences in heat tolerance, yield and horticultural traits. Among them, # 62, # 85-202 and Jinbai 45 were the most outstanding ones in terms of high yield, early maturity and heat resistance, and they were the excellent varieties of heat-resistant Chinese cabbage which are worth popularizing and applying in summer in Tianjin.
