Screening of tomato lines under combined stress in generative stage

Identification of lines with superior performance under combined stress same as (1) Three individual trials, 2018 - 2019 <em>S. lycopersicum; S. pennellii; S. lycopersicum x S. pennellii</em> Greenhouse @ University of Bonn (50.62 N 6.99 E) Growing plants in rockwool slabs with drip irrigation (as commercial practise); stressed plants received modified nutrient solution and only 50 % water General drop in fruit yield and quality under stress conditions; Performance of tested lines (eg water use efficiency) differ significantly. in progress to be discussed本试验旨在鉴定与试验（1）采用相同复合胁迫条件下表现优异的株系，共设置3组独立重复试验，实施周期为2018-2019年。供试材料包括番茄（*Solanum lycopersicum*）、潘那利番茄（*Solanum pennellii*）及其杂交组合（*S. lycopersicum* × *S. pennellii*）。试验地点位于波恩大学（University of Bonn）温室，地理坐标为50.62°N，6.99°E。供试植株采用岩棉块栽培并配合滴灌系统，遵循商业化生产的操作规范；胁迫组植株施加改良型营养液，灌溉水量仅为正常水平的50%。胁迫条件下，供试材料的果实产量与品质普遍下降；各待测株系的相关性能（如水分利用效率（water use efficiency））存在显著差异。本数据集仍处于完善阶段，相关内容待后续讨论。
