Rice productivity and output have always been threatened by natural disasters, pests and other environmental factors. Among those, salt-water land is a warning issue. Resbiction in impacts of salt water on rice productivity requires concerns and study. Moreover, in selection of rice species, researching method which exploits natural varieties in genes among parent species for hybrid process is an effective direction. FIA78 rice (being breed for QTI./Saltol gene) has agrobiology features similar to several species which are being grown widely in Red river delta and has salt-water adapting ability similar to Pokkali rice under the same experimental conditions.
