The International Cocoa Organization recognized Colombian cocoa as "fine aroma," but in recent years, clone CCN 51 has grown in popularity, widely due to its high yield. The Tolima department is the fourth producer of cacao in Colombia, but there is a lack of knowledge of the chemical properties of regional cocoa genotypes. The aim of this study was to evaluate the morphological, antioxidant activity, total polyphenol content and the methylxanthines ratio of four regional genotypes (UTLP02, UTVE01, UTGC01 and UTLM02) of L. from Tolima, Colombia. The universal clone of CCN51 was used as control. The highest values for the qualitative descriptors were obtained by the variants UTVE01 and CCN51 with FRAP and TPC ranging from 44.51 ± 0.90 to 106.77 ± 5.21 mg GAE/g and 27.13 ± 0.14 to 52.12 ± 4.71 mmol TE/g respectively. The genotypes with the highest values for FRAP and TPC were UTGC01 and CCN51. According to the methylxanthine ratio, UTVE01 was classified as Criollo, while UTLM02, UTGC01 and UTLP02, CCN51 are Trinitario and Forastero, respectively. Although CCN51 is considered a remarkable material in terms of productivity, the genotypes evaluated present good yields and interesting values of TPC and antioxidant activity, making them promising trees in local breeding programs.
国际可可组织将哥伦比亚可可认定为“优质香气型”，但近年来，CCN 51克隆品种越来越受欢迎，这主要归功于其高产特性。托利马省是哥伦比亚第四大可可生产地，但人们对该地区可可基因型的化学特性缺乏了解。本研究的目的是评估来自哥伦比亚托利马省的四种地方基因型（UTLP02、UTVE01、UTGC01和UTLM02）的形态、抗氧化活性、总多酚含量以及甲基黄嘌呤比例。通用的CCN51克隆品种用作对照。定性描述符的最高值由UTVE01变种和CCN51获得，其FRAP（铁离子还原抗氧化能力）和TPC（总多酚含量）分别在44.51±0.90至106.77±5.21毫克没食子酸当量/克和27.13±0.14至52.12±4.71毫摩尔TE/克范围内。FRAP和TPC值最高的基因型是UTGC01和CCN51。根据甲基黄嘌呤比例，UTVE01被归类为克里奥罗型，而UTLM02、UTGC01和UTLP02、CCN51分别为特立尼达型和弗拉斯特罗型。尽管CCN5在产量方面被认为是一种出色的材料，但所评估的基因型具有良好的产量以及有趣的TPC和抗氧化活性值，使其成为当地育种计划中有潜力的树种。
