Sixteen introductions of pepper (Capsicum annuum) were tested for drought resistance. Watering was stopped to the plants grown in perlite in pots to induce drought. After certain period of time, WSD value and stomatal density of mature leaves were measured for evaluation of drought resistance. A correlationship between WSD value and stomatal density was determined. On the basis of WSD value, the most drought-resistant varieties were No.3446, C. chacoence, Gogoshari, and Yatsufusa in a descending order and a significant positive correlation, r=0.581, between WSD value and stomatal density was observed.
