Potato (Solanum tuberosum L.) is a cool weather crop and one of the most important vegetables in the world, which is cultivated in temperate, subtropical, and tropical climates. Nearly all cultivated areas in Brazil use cultivars from temperate countries, resulting in lower performances particularly due to higher temperatures. The aim of this study was to identify clones that yielded better than foreign cultivars, both under high and mild temperature conditions. The study assessed 57 clones from the potato breeding program of the Universidade Federal de Lavras (UFLA), Brazil, and five check cultivars (Agata, Asterix, Atlantic, Cupido, and Markies). We evaluated the agronomic performance using the total and marketable tuber yield, dry matter content (DM), season length, and external tuber quality, in four experiments designing in a random complete block, during the seasons 2014 and 2015. The genotypes' stability, as well as the discrimination between environments, was performed using the GGE-Biplot method. Twenty heat-tolerant clones responded favorably to mild temperatures. This breeding program has generated clones more productive and better looking than commercial cultivars, for the different market segments: two for the fresh market (GMR 17-40; GMR 12-10), four for frozen French fries (CBM 07-78; CTB 03-02; GMR 15-42; SR2 35-05) and seven for potato chips (CBM 16-16; SR1 07-16; GMR 03-58; SR3 19-24; SR2 57-02; SR1 04-06; SR3 32-04).

热带气候高温和温和条件下优良马铃薯无性系的表现

马铃薯(Solanum tuberosumL.) 是一种凉爽气候作物,是世界上最重要的蔬菜之一,在温带、亚热带和热带气候中均有栽培。巴西几乎所有的耕地都使用来自温带国家的栽培品种,导致性能下降,特别是由于温度较高。本研究的目的是鉴定在高温和温和温度条件下产量均优于外来栽培品种的克隆。该研究评估了来自巴西联邦大学 (UFLA) 马铃薯育种计划的 57 个克隆和五个检查品种(Agata、Asterix、Atlantic、Cupido 和 Markies)。我们使用总的和可销售的块茎产量、干物质含量 (DM)、季节长度和外部块茎质量,在随机完整块设计的四个实验中评估了农艺性能,在 2014 年和 2015 年的季节。使用 GGE-Biplot 方法执行基因型的稳定性以及环境之间的区分。二十个耐热克隆对温和的温度反应良好。该育种计划为不同的细分市场产生了比商业品种更高产和更好看的克隆:两个用于新鲜市场(GMR 17-40;GMR 12-10),四个用于冷冻炸薯条(CBM 07-78;CTB 03-02;GMR 15-42;SR2 35-05)和七种薯片(CBM 16-16;SR1 07-16;GMR 03-58;SR3 19-24;SR2 57-02;SR1 04-06; SR3 32-04)。
