Potato is one of the most important crops in the world. Tuber is the commercial product of potato, whereas tuber greening seriously affects product quality and results in a large amount of potatoes waste. It is very necessary to establish a convenient evaluation method of tuber greening for the identification of potato germplasm resources and the analysis of tuber quality. In this study, we systematically evaluated the greening trend and greening degree of 15 potato tetraploid and diploid varieties (lines) base on the extraction of tuber color space characteristics and RGB color space color difference. Zhongshu 2, Zhongshu 18, Zhongshu 19, Atlantic, Favorita, and Kondor appeared faster greening speed, but HS66 appeared slower greening speed under 25℃ and 125 μmol m2 s1. Color difference value of tubers of all potato varieties (lines) tended to the stability after 9 days lighting treatment. There was an obvious greening extent differences among potato varieties (lines). Among them, the afforestation degree of Favorita was the highest, whereas Zhongshu 28 was the lowest after 13 days lighting treatment. The method established in this study can accurately distinguish the greening speed and the extent of different varieties (lines), which provided a convenient and reliable technical reference for tuber greening evaluation.

| Abstract (Chinese): |
马铃薯是世界上最重要的作物之一, 块茎作为马铃薯的商品器官, 块茎绿化严重影响马铃薯商品品质, 造 成大量的资源浪费。建立一种方便快捷的块茎绿化评价方法, 对于马铃薯种质资源鉴定和块茎品质评价具有重要意 义。本研究基于提取块茎颜色空间特征, 结合 RGB 颜色空间色差分析, 对 15 个马铃薯四倍体和二倍体品种(系)材料 的绿化趋势和绿化程度进行了系统评价。供试材料块茎在 25℃条件下, 125 µmol m-2 s-1 光照强度下, 中薯 2 号、中 薯 18 号、中薯 19 号、Atlantic、Favorita 和 Kondor 的绿化速度较快, HS66 的绿化速度较慢。在光照处理 9 d 后, 块 茎色差值趋于稳定, 在光照处理 13 d 后, 不同品种绿化程度差异明显, 其中 Favorita 的绿化程度最大, 中薯 28 号的 绿化程度最小。本研究建立的基于 RGB 颜色空间的马铃薯块茎绿化评价方法能够准确区分不同品种(系)的绿化速度 和绿化程度, 该方法简便、高效, 结果可靠, 为精准评价块茎绿化程度并进行相关分析提供了技术方法参考.
