Evaluation of salt tolerant ability of summer rice varieties in the Mekong Delta Huynh Ky Tran Huu Phuc Van Quoc Giang Tran Thi Yen Nhi Nguyen Loc Hien Nguyen Chau Thanh Tung Abstract The study aimed to evaluate salt tolerance ability in rice by screening in Yoshida solution complemented with 100 mM NaCl for 5 days. The results showed that survival rate growth rate were sharply reduced after 5 days of treatment. In addition the accumulation ability of Na K in the plant showed that the varieties including Ba Bui 2 Mot Bui Trang Tra Long 2 Tai Nguyen Ca Mau Nang Quot Bien Mot Bui Lun Tai Nguyen TT Ba Bui Lun and Doc Phung belonged to salt tolerant rice group. This result is the first step to select salt tolerant rice varieties in Yoshida solution for determining the parents with salt tolerant ability for future rice breeding purpose in the Mekong Delta.
