The results showed that under the environmental conditions in Guiyang,the flowering time,number of seeds per silique,plant height and thousand seed weight differed significantly among different lines. The results of principal component analysis showed that the lines could be classified into three groups. The results of Pearson correlation tests showed that the plant height was positively correlated with the flowering time( P < 0. 05),and the thousand seed weight was negatively correlated with the flowering time and number of seeds per silique( P < 0. 01).展开更多

In Guiyang environment,the oil content and protein content of these materials showed abundant variation,and were divided into three groups. Correlation analysis showed that there was a significant negative correlation between oil content and protein content of B. campestris L. seeds,and the application and formation mechanism of the negative correlation were also discussed.展开更多
