تقييم مؤشرات تحمل الجفاف في القمح القاسي تحت ظروف بيئية مختلفة

الملخص EN

Drought is the major environmental factor limiting wheat grain yield in the Mediterranean region.

Wheat improvement for drought tolerance requires reliable assessment of genotypes.

This study was conducted to assess the most important criteria for identifying drought tolerance: stress tolerance (TOL), geometric mean productivity (GMP), stress susceptibility index (SSI) and stress tolerance index (STI) in order to screen drought-tolerant durum wheat genotypes, and identify criteria associated with yield components.

The trials were carried out in two contrasting environmental sites: Tel Hadya (supplementary-irrigation), and Breda Drought is the major environmental factor limiting wheat grain yield in the Mediterranean region.
