Screening of tomato lines under combined stress in generative stage

Identification of lines with superior performance under combined stress same as (i) Three individual trials, 2018 - 2019 S. lycopersicum; S. pennellii; S. lycopersicum x S. pennellii 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. (viii) in progress (ix) to be discussed
