Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, the flow process of the embodiment of the present invention is as follows:

[0024] The first step is the selection of modeling sample set

[0025] A step-by-step modeling method is used to find representative samples, and a certain number of representative peanut single seeds of different genotypes are selected as the standard sample set for building the model. The number of samples should be no less than 150. This implementation A total of 230 samples were selected and collected as standard sample sets. Peanut single seed materials come from 200 different varieties or lines, which belong to the pearl bean type in classification; the sources of materials also include different years and seasons and different production areas. The variation range of oil content in the sample set is 30.80%-66.89%, and the sp...

Abstract

The invention is a nondestructive method of determining the oil content in a single peanut seed, based on Fourier transform near-infrared spectrometry and combined with chemical metrology method, adopting diffuse reflection determining mode, and using single seed of multigene peanut as sample to establish a multielement recurrent mathematical model, and then forecasting the oil content in the unknown sample by this model. It is nondestructive without any preprocessing of the sample and does not damage activity and tissue structure of the seed. It has simple operation, fast determining speed and higher determining accuracy. It is applied to high-oil quality peanut breeding, seed quality resources evaluation and research on genetic law.

Description

technical field [0001] The invention relates to the technical field of quantitative analysis of peanut seed quality components, in particular to a method for nondestructively measuring the oil content of a single peanut seed by applying Fourier transform near-infrared spectrum analysis technology and combining modern chemometric methods. Background technique [0002] The conventional chemical method for determining the oil content of peanut seeds generally adopts the Soxhlet method. The sampling method and sample pretreatment method of this assay method are both destructive, and there are also disadvantages such as time-consuming and laborious, cumbersome assay procedures, and high assay costs. In peanut quality breeding and genetic research, there is a great need for fast, real-time, easy-to-operate analysis methods that do not destroy samples. In peanut quality breeding for the purpose of improving oil content, there is an urgent need for analytic...
