中文摘要:

【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。

英文摘要:

【Objective】 The correlation between economic traits and quality traits of spring rapeseed(Brassica campestris L.) was studied, and the main indicators for determining the yield and oil content of spring rapeseed were selected. 【Method】 Taking 41 spring rapes arranged by Tibet Academy of Agriculture and Animal Husbandry Sciences as materials, the economic traits such as plant height, branch position, number of branches, length of main sequence, main sequence pod, pod density, number of pods per plant, pod length, per-fruit seed number, yield per plant, and 1000-grain weight were detected. The oil content, erucic acid and glucosinolate contents of rapeseed were detected by near-infrared quality analyzer. Cluster analysis of 41 materials was conducted and correlation between indicators was analyzed. 【Results】 The results of correlation analysis showed that the number of branches, the number of pods per plant, the pods of main inflorescence, the length of pods and the yield of rape were significantly or highly significantly correlated, and the correlation between other economic indicators and yield was not significant. Oil content was negatively correlated with erucic acid content, but with no significant correlation.【Conclusion】The number of branches, the number of pods per plant, the pods of main inflorescence, and the length of pods can be used as the main indicators for the evaluation of spring rapeseed yield, and other economic indicators as secondary indicators. Erucic acid can be used as a reference for the evaluation of oil content.
