Research and application of molecule markers in breeding salt-Tolerant Bacthom 7 rice variety

-In the current study, some rice varieties with salinity tolerance and acceptable yield were evaluated (as FL478 and IR55179-3B-11-3 varieties). - FL478 was used as the donor (QTL/gen Saltol) which has some agronomical traits similar with some widely grown rice varieties in Red River Delta (50,2 ta/ha – 55,3 ta/ha), especially, its salinity tolerance showed at point 3, equivalent with Pokkali variety in the same experimented condition. - BT 7 was used as the recipient plant - 102 polymorphic markers were identified (accounting for 21,38 %) between BT7 and FL478 . - 94 polymorphic markers distributed on the 12 chromosomes were identified and use to select the carried Saltol gene that attained the highest genetic background of the recurrent parents in the backcrossed populations. - Applying marker assisted backcrossing to select the plants number IL30 and IL32 from the generation of BC3F1 had the maximum genetic background up to 99,3% and 100% of BT7 - BT7-Saltol (BC3F4) was developed by MAB which showed salinity tolerance at point 3, similar with salt tolerance ability of FL478. - Most of rice lines showed phenotypic characteristics similar with BT7 at 100% based on the criteria and carried QTL/gen Saltol with salinity tolerance at poit 3 as the Pokkali. - 8 potential BT7-Saltol (BC3F4) with acceptable yield and quality similar with BT7 were developed.
