Dataset for: Adaptation and Efficiency Trials (CIP396034.103) - Season I

In 2019-2020 season, three clones with high levels of resistance to late blight were evaluated in adaptation and efficiency trials for tuber yield, dry matter content, frying and baking quality throughout Peru in six locations, compared to two varieties planted by farmers. and very well accepted by final consumers, Canchan and Unica, these are currently also used for frying in sticks, but without stability in all crops due to the genotype x environment interaction. The randomized complete block design was used with three replications of 150 plants, the fertilization dose was 200-220-180 Kg of NPK, using potassium sulfate as a source of potassium to improve frying quality. At harvest, samples were taken to determine dry matter, reducing sugar content, traditional and blanched frying color, and baking quality. The clone was equal to or superior to the controls for the yield of tubers, it presented good quality of frying color in all localities compared to the control varieties that did not present good quality of frying color in all localities, It is expected to complete all the documents requested by the Peruvian Seed Authority (SENASA) to be registered as a new potato variety with resistance to late blight and quality for frying and / or baking.

2019-2020年度试验季中，针对3个高抗晚疫病（late blight）的马铃薯克隆株系，研究人员于秘鲁境内6个试验地点开展了适应性与生产效率评价试验，测定指标包括块茎产量、干物质含量、油炸及烘烤品质，并以当地农户广泛种植、深受终端消费者认可的两个品种Canchan与Unica作为对照。该对照品种目前亦用于薯棒类食品的油炸生产，但因基因型×环境互作（genotype x environment interaction）效应，在不同种植环境下的表现稳定性欠佳。试验采用完全随机区组设计（randomized complete block design），设置3次重复，每个重复种植150株；施肥方案为NPK肥用量200-220-180 kg/ha，选用硫酸钾作为钾源以优化油炸品质。收获阶段采集试验样本，用于测定干物质含量、还原糖含量、传统油炸及漂烫后油炸的色泽，以及烘烤品质。结果显示，该供试克隆株系的块茎产量不低于甚至优于对照品种，且在所有试验地点均展现出优良的油炸色泽品质；反观对照品种，其油炸色泽品质在各试验地点间表现参差不齐。目前正筹备完成秘鲁种子管理局（SENASA）要求的全部注册申报文件，以期将该克隆株系登记为兼具晚疫病抗性、油炸及/或烘烤优良品质的马铃薯新品种。
