Replication data for: New Elite Potato Clones with Heat Tolerance, Late Blight and Virus Resistance to Address Climate Change

In 2012–2013, 61 advanced clones resulting from selection at San Ramon, La Molina and Oxapampa were assessed for tuber yield in San Ramon, La Molina and Majes under high temperatures. All trials were conducted in a simple lattice design, with 20 plants per plot, using two varieties as controls: (i) Désirée as heat tolerant; and (ii) Amarilis as heat sensitive. The traits measured were plant vigour, foliage maturity at harvest, tuber appearance, marketable tuber number and marketable and total tuber yield. Analysis of variance for tuber yield and the additive main effects and multiplicative interaction (AMMI) model for stability analysis were performed using the statistical software R (R Core Team, 2012). The results of the AMMI model analysis were interpreted on the basis of two AMMI graphs for principal components and tuber yield.

2012—2013年，研究人员针对从圣拉蒙（San Ramon）、拉莫利纳（La Molina）与奥克萨潘帕（Oxapampa）选育获得的61个高级无性系，在高温环境下的圣拉蒙、拉莫利纳和马赫斯（Majes）三个试验点开展块茎产量评估。所有试验均采用简单格子试验设计，每个小区种植20株供试材料，并设置两个对照品种：（i）耐热品种Désirée；（ii）热敏感品种Amarilis。本试验测定的性状包括植株长势、收获期茎叶成熟度、块茎外观、商品块茎数量、商品块茎产量及块茎总产量。研究采用统计软件R（R Core Team, 2012）对块茎产量进行方差分析，并采用加性主效应与乘性交互作用（Additive Main effects and Multiplicative Interaction, AMMI）模型开展稳定性分析。AMMI模型的分析结果基于主成分与块茎产量的两幅AMMI图进行解读。
