Rice breeding for yield under drought has selected for longer flag leaves and lower stomatal density
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Direct selection for yield under drought has resulted in the release of a number of drought-tolerant rice varieties across Asia.In this study, we characterized the physiological traits that have been affected by this strategy in breeding trials across sites inBangladesh, India, and Nepal. Drought- breeding lines and drought-tolerant varieties showed consistently longer flag leavesand lower stomatal density than our drought-susceptible check variety, IR64. The influence of environmental parameters otherthan drought treatments on leaf traits was evidenced by close grouping of treatments within a site. Flag-leaf length and widthappeared to be regulated by different environmental parameters. In separate trials in the Philippines, the same breeding linesstudied in South Asia showed that canopy temperature under drought and harvest inde' .
