We generated 55 introgression lines via backcrosses using Milyang23 as the recurrent parent and Oryza glaberrimaas the donor. 141 SSR markers were used to genotype 55 introgression lines. The 55 introgression lines with Milyang23 wereevaluated for physiological traits; fresh shoot weight (FSW), fresh root weight (FRW) and dry shoot weight (DSW) under thecontrol and 30% PEG-treated condition. Three lines showing significant difference with Milyang23 were selected for furtheranalysis. Three lines had four, four and two O. glaberrima homozygous segments, respectively. IL9 performed better thanMilyang23 in all traits measured in the 30% PEG-treated condition. IL9 possessed four O. glaberrima introgressions onchromosomes 1, 2, 6 and 7. IL12 performed better than Milyang23 in FSW and FRW. IL55 contains two O. glaberrimaintrogressions on chromosomes 2 and 6. Three lines shared the O. glaberrima segment delimited by markers RM133-RM225 atchromosomes 6. This region corresponds to the QTL region for drought tolerance reported by other previous studies. AlthoughIL9 and IL12 showed improved drought tolerance at the seedling and vegetative stage, they performed poor under the droughtstress at the reproductive stage implying that the level of drought tolerance differs according to the growth stage in rice. IL55had significantly higher no. of the total grain than Milyang 23. This result seems to indicate that IL55 will be a good resourcefor drought tolerance breeding. The population would be useful in developing drought tolerant lines in the breeding program.
