Development and Rapid Adoption of Submergence-Tolerant (Sub1) Rice Varieties
<|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:'Flooding is a frequent hazard in lowland rice environments and is expected to intensify with climate change. Short-term submergence regularly affects over 20 million ha of rice in the tropics. Tolerant varieties like the Indian landrace FR13A can survive submergence for 2 weeks or more, whereas susceptible varieties are severely damaged or killed within a week. The discovery of the tolerance gene SUB1 enabled marker assisted backcrossing to transfer it into rice mega varieties, and eight 'Sub1 varieties' were recently developed in the background of popular Asian cultivars. Five have been officially approved for distribution to farmers and the remaining three are under advanced evaluation. The Sub1 varieties have grain yields equal to their parent varieties under non-submerged conditions and yield advantages of 1t/ha or more when affecte' .
