一般生產上良種的貢獻率約占30～40%，而在高油大豆生產中，從商品含油率看；高油品種的貢獻率可以達到80%yishang。jinnianlai

    一、品種成熟期適宜，確保霜前充分成熟積溫、生sheng育yu日ri數shu和he熟shu期qi是shi否fou近jin似si於yu當dang地di主zhu栽zai品pin種zhong
，是shi衡heng量liang品pin種zhong熟shu期qi適shi宜yi與yu否fou的de主zhu要yao標biao準zhun。其qi中zhong，又you以yi熟shu期qi近jin似si於yu當dang地di主zhu栽zai品pin種zhong這zhe一yi標biao準zhun更geng為wei準zhun確que可ke靠kao。因yin為wei大da豆dou生sheng長chang發fa育yu對dui光guang照zhao比bi較jiao敏min感gan，積ji溫wen和he生sheng育yu日ri數shu隻zhi是shi特te定ding地di區qu生sheng育yu表biao現xian的de相xiang對dui平ping均jun值zhi，往wang往wang因yin年nian份fen

、地點而變化。此外，品種生育進程與氣候季節變化的協調同步，也是實現高油大平高產的前提之一。 

    二
、品種含油率高一般大豆含油率應在20%以上，高油大豆應在22%以上
，純糧率98%以yi上shang，前qian者zhe才cai能neng達da到dao一yi級ji標biao準zhun，後hou者zhe可ke達da特te級ji標biao準zhun。當dang前qian應ying避bi免mian在zai高gao油you大da豆dou品pin種zhong受shou重zhong視shi的de情qing況kuang下xia

    三
、品種產量潛力高、適shi應ying性xing強qiang且qie豐feng產chan性xing好hao選xuan用yong高gao油you品pin種zhong不bu可ke忽hu視shi品pin種zhong的de產chan量liang潛qian力li
，這zhe也ye是shi高gao產chan形xing成cheng的de前qian提ti之zhi一yi。由you於yu不bu同tong品pin種zhong對dui當dang地di肥fei水shui等deng條tiao件jian的de利li用yong率lv和he適shi應ying性xing不bu同tong

，實現更大幅度的增產。
