Abstract:: In order to select suitable high-quality varieties for open field cultivation in southern mountain area of Ningxia，with 16 cauliflower varieties as test materials，using randomized block experimental design，biological traits and yield of the 16 varieties were analyzed and compared.The results showed that the 667 m2 yield of two varieties of ‘Jieya’ and ‘Fuguibaota’ were 3 967 kg and 2 923 kg，respectively，the total sugar content of ‘Jieya’ was 27.7 g?kg-1，‘Fuguibaota’ of vitamin C was 612 mg?kg-1，black spot disease resistance of ‘Jieya’ and ‘Fuguibaota’ were 97% and 90%，seedling blight resistance all were 100%，with strong growth potential，strong drought resistance，comprehensive traits were significantly better than the other varieties.So ‘Jieya’ and ‘Fuguibaota’ were suitable for mountainous regions of Southern Ningxia，which were exposed to cultivation in summer.
