用油研七号的不育和恢复亲本22A和821－77进行早熟性定向系统选择，育成了早熟2287A和早熟821，所配制的“早熟油研七号”（尚未审定，因需要暂用此名，下同）生育期平均提早2天，一次有效分枝数、单株有效角、千粒重等性状比油研七号分别多0.53个／株，39．6个／株和0.229，产量比原油研七号增产3．08％。
The sterile selection and restore parents of oilseed cultivar No.7 were used to select the early sexual orientation system. The early maturing 2287A and the early maturing 821 were bred, and the “Precious Oil Research No.7” (not yet validated because of the need to temporarily use this The average growth period was 0.53 / plant, 39.6 plants / plant and 0.229, respectively. The yield was higher than that of crude oil Research seventh increased 3.08%.
