Water stress can affect the yield in tomato crops and, despite this, there are few types of research aiming to select tomato genotypes resistant to the water stress using physiological parameters. This experiment aimed to study the variables that are related to the gas exchanges and the efficiency in water use, in the selection of tomato genotypes...
The objective of this study was to evaluate the physiological behavior of different tomato genotypes to assist in the selection of plants with tolerance to drought stress. It was used three blocks random and ten treatments: Eight genotypes F2RC1 [UFU80- F2RC1 #1 (3.5); UFU102- F2RC1 #7 (13.4); UFU102- F2RC1 #7 (13.3); UFU102- F2RC1 #7 (16.8); UFU10...

... High Pn associated with low gs was observed in water stress tolerant plants which had higher iWUE (Pazzagli et al., 2016). Borba et al. (2017) reported high Pn and low gs and E, and better water use efficiency in F 2 BC1 population of Solanum pennellii x S. lycopersicum cross. Both A1-63/79 and Man-63/79 were better than their respective parents with respect to iWUE. ...

... In literature, great emphasis has been attributed to what is called water use efficiency (WUE), which is a useful feature for breeders to analyze when selecting genotypes presenting the desirable phenotypic performance, even when submitted to water deficiency. According to Rocha et al. (2016), selecting genotypes tolerant to water deficiency must consider mechanism to reduce water loss while maintaining biomass production. Those values displayed by line 16 confirmed its classification as "responsive to water availability improvement" and "tolerant in the presence of water deficiency". ...
