摘　　要：【目的】挖掘种仁抗褐化能力强的锥栗资源,筛选出果实适合深加工型的锥栗良种。【方法】从96份笔者课题组前期调查的资源中优选30份不同锥栗种质资源的种仁,通过对其种仁褐变程度、总酚和维生素C含量的测定,根据不同优株果实种仁褐变差异性及其内含成分进行聚类分析和相关性分析。【结果】锥栗种仁褐变程度差异显著,种仁抗褐化能力与褐变指数呈负相关,在30份资源中,ZNL-1、JZPYS-1与ZNL-15褐变指数较小,分别为0.067、0.083与0.150,ZNL-4和ZNL-13褐变指数较大,分别为0.600与0.650;30份种仁总酚含量差异显著,种仁褐变与总酚的含量呈正相关,其中ZNL-15种仁中总酚含量最低,为27.91 mg·100 g^(-1),而ZNL-13的种仁中总酚含量最高,为229.65 mg·100 g^(-1),为最低的8.2倍,同时褐变程度也最高;维生素C含量差异较显著,种仁褐变与维生素C含量的相关性弱,其中ZNL-15维生素含量高达67.23 mg·100 g^(-1),是含量最低ZNL-2的2.1倍。【结论】种仁抗褐变的优株为ZNL-1、ZNL-15与JZPYS-1,可用作锥栗杂交培育新品种的亲本,向锥栗产品深加工与利用方面拓展挖掘。【Objective】Castanea henryi, a chestnut species belong to the Fagaceae, was one of the woody species of grain in China. Due to its good economic value and good fruit quality, C. henryi was high popularity in broad consumers. However, the browning phenomenon of C. henryi occurred frequently in the process of storage which directly affected the appearance, flavor, and lower quality of products. Thus it is especially important to study of the ability to resist browning in C. henryi. To explore anti-browning ability resources and get the C. henryi fruit processing plant type, we selected the optimal plant type from superior plants, which is suitable for deep processing of C. henryi.【Methods】Previous collected 96 excellent individuals branches of C. henryi from some regions of Hunan and Fujian, though the method of Crown-grafting in agricultural base in Rucheng, Hunan, which was cooperate with Central South Forestry University of Science and Technology in 2012, then we got 30 samples in2015. The experiment was carried out with a randomized block design. Taking 30 different superior plants＇ seeds of C. henryi as the test materials with boiling water bath after 20 minutes, we made it to be binary segmentation and comparative screening. We observed its browning phenomenon, and divided the browning phenomenon into six grade（level 0 was no browning, and keep original color and texture. Level 1 was mild browning, and section was slightly brown, and the brown area was 10%. Level 2 was moderate browning, and apparently occurred browning, but the original color and texture were still clearly visible, and browning area was 20%. Level 3 was severe browning, and the original color and quality of a material were hard to discern and ambiguous, and browning area was 30%. Level 4 was extreme browning, which was unable to identify initial color and texture, and browning area was 40%.Level 5 was the initial basic color disappeared, quality of a material to harden, and browning area was more than 50%）. Then we through the s
