Potato is the third most important food crop in the world after rice and wheat. Because of its widely distributed cultivation and high yields, it is considered a critical species in terms of food security in face of a growing world population. However, potato is particularly vulnerable to high temperature during various stages of its life cycle. Elevated temperatures strongly suppress tuberisation, negatively affect storage and shelf life of tubers and reduce fitness of seed potatoes. Breeding new heat-stress tolerant cultivars is an urgent need for sustainable increases in potato production, given the negative impact of the rises in temperature due to global warming. In this proposal, an integrated approach will be used by combining physiology, genetics, genomics, metabolomics and natural variation studies to analyze the impact of elevated temperatures on (1) sink-source relations of potato plants, (2) potato tuber development, (3) starch accumulation and tuber quality and (4) tuber dormancy. The outcomes of the project will be new knowledge of potato genes and their function that can be used in breeding programmes to increase yields in warmer climates.

马铃薯是仅次于水稻和小麦的世界第三大粮食作物。由于其广泛分布的种植和高产量，它被认为是面对不断增长的世界人口的粮食安全方面的关键物种。然而，马铃薯在其生命周期的各个阶段特别容易受到高温的影响。高温强烈抑制块茎形成，对块茎的储存和保质期产生负面影响，并降低种薯的适合度。鉴于全球变暖造成的气温上升的负面影响，培育新的耐热品种是马铃薯产量可持续增长的迫切需要。本研究将采用生理学、遗传学、基因组学、代谢组学和自然变异相结合的综合方法，分析高温对马铃薯植株库源关系、块茎发育、淀粉积累和块茎品质以及块茎休眠的影响。该项目的成果将是关于马铃薯基因及其功能的新知识，可用于育种方案，以增加温暖气候下的产量。
