Evaluation of the yield of strawberry genotypes by morpho-physiological parameters under deficit irrigation in the Mediterranean environment

The most pressing concern of the century is food security, mostly supported by irrigated agriculture. In this respect, studies on water stress have drawn increased attention with a highlighting expectation foreseen via our breeding efforts documented in study concerning significant commercial strawberry cultivars ‘Rubygem’, ‘Sabrina’ and ‘Festival’ along some selected superior bred lines (‘33’, ‘36’, ‘59’, ‘61’ ‘112’). Plants cultivated Spanish-type high tunnel were exposed to both full (IR100) deficit irrigation (IR50) Mediterranean part Türkiye. Fruit yield as well certain critical morphological physiological parameters examined throughout active harvest period. This found that relating vegetative components, fruit weight yield, drastically dropped when plants subjected irrigation. Therefore, depending limited irrigation, result closure stomata, it was concluded amount stomatal conductance plant associated decrease. IR50 less impact low-yield genotypes than high-yield genotypes. Photosynthetic activity conductivity ‘33’ line yield. On other hand, photosynthesis leaf potential (LWP) values relatively low ‘36’ proved variables like photosynthetic activity, conductance, LWP could be used markers for genotype selection.
