Embodiment 1
[0023] A method for rapidly measuring tocopherol content in Brassica napus seeds by utilizing near-infrared spectroscopy, comprising the following steps:
[0024] 1. Collect Brassica napus samples.
[0025] To ensure the accuracy of the analytical model, a batch of rapeseed seeds with rich genetic diversity must be selected. In view of this, firstly, using a representative batch of rapeseed inbred lines collected from all over the country, through molecular marker analysis and tocopherol content determination, 373 strains were screened out with relatively high levels of tocopherol content, population structure and genetic diversity. Brassica napus seeds with large differences, and then the 373 materials were divided into two groups, the first group was used as the calibration set to establish the near-infrared correction model; the second group was used as the validation set to verify the accuracy of the near-infrared correction model , including 302 calibration sets and 71 v...
