Outline of Final Research Achievements

In biorefinery, sugar is a key molecule, and genes controlling brix is the key genes. In our previous studies, the introgression of a QTL associated brix (qBRX-6) detected in sweet sorghum (SIL-05) increased the brix score in culm. However, Ma1/SbPRR37 disturbed the marker assisted selection in breeding, because it located nearby qBRX-6. In this study, we narrowed down the candidate region of qBRX-6 into about 190kb using a chromosome segment substitution line. Based on this results, we established a DNA marker that can distinguish two loci.
