为寻找最佳光谱检测部位,创新一种高油酸油菜种质资源筛选方法,以44个高油酸含量的甘蓝型油菜为材料,按照从主茎、一次分枝到二次分枝的顺序,采集籽粒反射光谱及油酸含量数据,分析不同部位的原始及一阶微分光谱与对应籽粒油酸含量的相关关系,建立了基于全波长、特征波长的逐步多元线性回归(stepwise multiple linear regression,SMLR)、偏最小二乘回归(partial least squares regression,PLSR)、主成分回归(principal component regression, PCR)估测模型和基于光谱指数的一元线性回归模型,用决定系数(R~2)、均方根误差(root mean square error, RMSE)、相对预测偏差(relative prediction devia...

In order to find the most typical characteristics part of rapeseed on its oleic acid content hyperspec‐tral estimating in Brassica napus L.,44 germplasm resources with high oleic acid content were used as materials.Spectral reflectance of seed and its oleic acid data were collected according to an order of main stem,primary branch,and secondary branch.The data were analyzed on relationship between seed oleic acid contents and original&first derivative spectral reflectance of different parts.Estimation model as stepwise multiple linear regressi...
