For example, by
breeding submergence tolerance into our existing high - performing varieties, they can now withstand up to two weeks of flooding and still yield well.
The group of rice (the aus - type) that Kasalath is part of is also the source of the submergence tolerance gene, which IRRI has used to
breed submergence - tolerant (Sub1) rice varieties that are being widely adopted across Asia.
Armed with the new knowledge, the researchers were able to
breed submergence - resistant plants that still produced decent rice yields, the team reports 10 August in Nature.

The finding of
submergence - specific genes should greatly accelerate the pace of
breeding optimal rice crops, he says.
India was the first country to get the
submergence - tolerant trait
bred into local mega-varieties, through collaborative programs with IRRI.
Many of these have contributed to rice
breeding programs, such as Pokkali for salinity tolerance, N22 for drought and heat tolerance, FR13A for
submergence tolerance, and Oryza nivara for resistance to grassy stunt virus.
