Abstract
 
To increase productivity and improve quality, new rice varieties need to be salinity tolerance and resistant to many kinds of insects, diseases, and high levels of nutrients, resistant to disadvantageous conditions, and promises to reduce using pesticides, chemical fertilizers. Great efforts have been focused on germplasm research to discover genes resistant to disease and insect, efficient in using salinity level with good grain quality and productivity. With the development of climate-resilient varieties, scaling up or dissemination of seeds is done by province, following the locality's is Winter-Spring (Dong Xuan Season) and Summer – ( Wet season ). For instance, in the case of Winter-Spring crop, the plan of Mekong delta is to expand some lines such as HATRI 190, HATRI 192, HATRI 170 were developed that can yield 4-5 tons ha-1 under salt stress of 10.0 to 12.0 dS m-1 , and are being out-scaled. Normally, this expansion initiative requires inclusion of key rice varieties, that is, local or extra varieties and promising varieties, all of which will be included in the plan for developing the rice sector for each province.
