云南油菜种质资源的品质鉴定研究

Identification and Research on Quality for Germplasm of Rapeseed in Yunnan Province

对云南油菜品种资源 371份的含油量、7种脂肪酸的组成成份和硫甙含量进行测试分析 ,结果为 :云南省油菜种质资源中具有含油量较高的优异种质资源 ,含油量的高低与海拔高度有一定的关系 ,即高海拔地区油菜的含油量普遍较高 ;云南省地方品种中缺乏低芥酸 (<1% )和低硫代葡萄糖甙 (<30 μmol/g)的种质资源 。

accessions of rape germplasm of Yunnan province were analysed with their oil content, fat acid and glucosinolates compositions and results were as follows: some high oil content resources were found The oil content is related with altitude and the high oil content varieties are found in high altitude regions With the shortage of low erucic acid (<1%) and low glucosinolates(<30 μmol/g)total content resources in Yunnan, rapeseed materials with low erucic acid and low glucosinolates for the needs of quality breeding in our province could be only introduced in our province
