- 摘要:
- 以黑龙江省92个主栽大豆品种（系）为研究对象，分别对其在2010年和2011年的脂肪含量进行分析，发掘与脂肪含量紧密连锁的SSR标记，用以辅助鉴定黑龙江省主栽大豆品种的脂肪含量。结果表明：供试材料脂肪含量变异范围2010年为17.10%~23.14%，2011年为17.70%~23.04%，两年平均为17.40%~23.09%。结合SSR数据的品种系统进化树分析，可以将黑龙江省主栽大豆品种脂肪含量总体上分成大于20%和小于20%两类。此外，鉴别出2个与脂肪含量相关的SSR标记（Satt428-900、Satt502-150），标记指数与脂肪含量显著相关（相关系数分别为-0.41*和0.41*）。
- Abstract:
- A total of 92 major soybean cultivars(lines)of Heilongjiang province,which were analyzed for the oil content in year of 2010 and 2011 respectively,were chosen as the object to explore SSR markers associated with oil content in order to identify the oil content of the cultivars(lines).Analysis of variance underlying oil content showed that the range of variation of tested materials for oil content was 17.1%-23.14% in 2010 and 17.7%-23.04% in 2011,and the average was 17.4%23.09%.The analysis of dendrogram of the cultivars combined with SSR data could roughly define the major cultivars of Heilongjiang province into two class with 20% as the border of oil content.Moreover,two SSR markers（Satt428-900,Satt502-150）,of which the label index showed significantly correlation with oil content with -0.41*and 0.41* as correlation coefficient respectively,were significantly correlated with oil content.
