The results show that there are four glutinous rice lines named N6, N14, N15, and N32 with high yields from 5.47 to 6.88 ton/ha, culm strength (scale 1), leaf blast resistance (scale 1-3), amylose content ranging from 2.0 to 2.1%, very low gelatinization temperature, good head rice recovery (>
53%), and all glutinous rice lines carry homozygous genotypes linked to target genes. Therefore, these four glutinous rice lines (N6, N14, N15, and N32) are suitable for testing ecological regions in the coming crop.
