DURUM WHEAT is commonly grown in water-limited environments where water use efficiency and drought-resistance traits play major roles in the successful adaptation of new genotypes to stressful environments. As stated by Austin (1980), an increase in the rate of photosynthesis per unit leaf area may cause substantial increases in dry matter production for the same or even less amounts of water use, while leaf area remains unchanged. A high net photosynthesis rate is considered to be one of the most important breeding strategies for better adaptation to stressful environments (Austin, 1987, 1989). Thus, detecting and exploiting genetic variation in photosynthesis rate could ...
