采用土培试验，对硼效率不同的甘蓝型油菜进行两步筛选。（１）苗期筛选：选择１３０个甘蓝型油菜品种，在缺硼和硼正常处理条件下，根据苗期地上部干物重经比（－Ｂ／＋Ｂ）作为硼效率系数，来反映不同品种硼效率差异，初步判断有硼高效品种２２个，硼低效品种２个，硼中效品种１０６个；（２）产量筛选：以Ｂ２（土壤有效硼０．２５ｍｇ／ｋｇ），Ｂ３（土壤有效硼１．０ｍｇ／ｋｇ）水平下油菜种子产量比（Ｂ２／Ｂ３）来反映不同
Under pot culture, twostep screening was taken on different boron efficiency rape (Brassica Napus L.) cultivars as following: (1) seedling screening. One hundred and thirty rape cultivars were selected to culture with boron deficiency and norm
