Abstract S565.4; [目的]研究西藏白菜型春油菜的经济性状与品质性状的相关性,分析决定春油菜产量及含油量的主要指标.[方法]以西藏自治区农牧科学院配置的41份白菜型春油菜为材料,检测春油菜株高、分枝部位、分枝数目、主序长度、主序角果、角果密度、单株角果数、角果长度、每果粒数、单株产量、千粒重等经济性状.采用近红外品质分析仪检测油菜籽含油量、芥酸、硫苷含量,并对41份材料进行聚类,分析指标间的相关性.[结果]相关性分析结果显示,分枝数目、单株角果数、主花序角果数、角果长度与油菜产量呈显著或极显著相关性,其他经济指标与产量的相关性不显著;含油量与芥酸含量呈负相关,但不显著.[结论]分枝数目、单株角果数、主花序角果数、角果长度可作为白菜型春油菜产量评价的主要指标,其他经济指标为次要指标;芥酸可以作为含油量评价参考指标.
