(Xinhua) -- Rice farmers living along
coastal areas will no longer have to abandon their
farms after the International Rice Research
Institute (IRRI) announced on Tuesday that it has
developed the super salt-tolerant rice.
IRRI revealed that the super salt-tolerant rice has
double the salinity tolerance of other rice
varieties, making it suitable for saline-stricken
rice farms in coastal areas. IRRI noted that rising
seawater cause rice farms along coastal areas to be

farmers because the encroaching seawater has

salt it takes from the soil into the air through
salt glands on its leaves.
said the new rice variety was bred by successfully
crossing two different rice parents—the exotic
wild rice species Oryza coarctata and rice variety
IR56 of the cultivated rice species O. sativa.
coarctata, IRRI noted, is a special type of rice
that grows in brackish, salty water. This makes it
highly resistant to saltiness in the soil.
