目的利用近红外漫反射光谱建立小麦抗旱性鉴定体系。 2006-2007年有针对性地选择36份抗旱性不同的小麦材料，通过利用小麦抗旱性鉴定评价技术体系规范（GBT21127-2007）进行抗旱性鉴定分类分级，同时利用FOSS NIRSystems5000型近红外谷物品质分析仪（全光谱分析仪），对收获后的小麦籽粒样品进行光谱采集，并建立预测回归方程。结果经过建库和验证，初步得到判别方程。经比较，水分胁迫下的方程参数RSQ（检验决定系数）=0.8460、I-VR（交互检验决定系数）=0.7818，品种的抗旱性和光谱特征的一致性较好，小麦籽粒近红外慢反射光谱与小麦的抗旱性具有较好的相关性。结论在水分胁迫的情况下，通过近红外漫反射光谱技术扫描小麦籽粒样品建立一套简单、快速、无损的小麦抗旱性鉴定体系是可行的。

[Objective] This study aimed to establish an identification system for drought-resistance in wheat by using near-infrared diffuse reflectance spectroscopy. [Method] In 2006-2007, 36 wheat varieties with different drought resistance were selected and were classified according to their drought resistance grades determined by the Technical Specification of Identification and Evaluation for Drought Resistance in Wheat (GB/T 21127-2007). In addition, the harvested wheat seed samples were spectrally analyzed with FOSS NIRSystems5000 near-infrared spectrum analyzer for grain quality (full spectrum analyzer) and then the forecasted regression equations were established. [Result] After the establishment of a database and validation, dis- criminated functions were obtained. The determination coefficient (RSQ) and coeffi- cients of determination for cross validation (1-VR) in the discriminant function built with seed samples from water stress area were 0.846 0 and 0.781 8, respectively, which indicated that the consistency between drought resistance and spectral charac- teristics in wheat varieties was good, and there was high correlation between the near-infrared diffuse reflectance spectra of seeds and the drought resistance in wheat. [Conclusiou] Under water stress condition, it is feasible to establish a conve- nient, rapid and no-damage identification system for the drought resistance in wheat by using the near-infrared diffuse reflectance spectrum technique to scan wheat seeds.
