摘　　要：Oilseed rape （Brassica napus L.） is one of the most important oil crops worldwide and provides about 50 percent of the vegetable oil supply in China （Yin et al., 2009）. The development of rapeseed varieties with higher yield is an effective measure to optimize balance between the supply and demand of edible vegetable oil. In oilseed rape, the number of silique per plant （SP） contributes most to the yield performance （Diepenbrock, 2000）. However, compared with the other two yield-component traits, seeds per silique （SS） and seed weight （SW）, SP is more sensitive to environmental changes （Li et al., 2007; Shi et al., 2009）. Therefore, it is difficult to perform the genetic improvement on SP trait directly in oilseed rape.Oilseed rape （Brassica napus L.） is one of the most important oil crops worldwide and provides about 50 percent of the vegetable oil supply in China （Yin et al., 2009）.
