| 520 | _aMaize farmers face numerous constraints, including drought and low nitrogen (N). Drought stress damages an estimated 3 to 22% of the planted area in Thailand annually, resulting in yield losses of approximately 129,000 to 858,000 metric tons (worth 10 to 80 million US dol1ars). Maize is usual1y susceptible to stress at flowering stage (Grant et al. 1989).The maize population KK-DR was developed from six local materials and was improved for drought tolerance in Thailand (Manupeerapan et al. 1996). Drought resulted in a reduction in growth, dry matter, and N concentration in parts of the p1ants at 29 days after emergence (DAE) (Kraokaew and Chinchet 1998). Genetic variation in response to N supply to the maize population (Lafitte and Edmeades 1994) and inbred lines (Balko and Russell 1980) was observed. An inbred-hybrid approach, as opposed to population improvement, was used to breed for such stresses. | ||
