| Research Abstract |
The evaluation method for cross-tolerance to water and oxidative stress was established in rice. Lines selected by the method showed better performance in oxidative stress tolerance and yield in field experiment. However, the other factors, such as nutrient uptake ability, also significantly affected the performance, suggesting several evaluation methods are suitable to select lines in addition to this method.
