Outline of Final Research Achievements

To improve the lodging resistance in rice using superior allele of strong culm genes in natural vaeients, the QTLs and causal genes for strong culm were identified using the backcross inbred lines (BILs) derived from Chugoku117 with a strong culms and Koshihikari. QTLs for the culm thickness were detected on chromosomes 2 and 3. We isolated responsible gene of SCM3 by positional cloning. SCM3 was narrowed down, and only one candidate gene was found. To evaluate the effect of SCM3 and the another strong culm gene SCM4 on lodging resistance, NIL-SCM3 and NIL-SCM4 were developed. These NILs showed enhanced culm strength and increased spikelet number due to the pleiotropic effects of the gene. These results demonstrate the importance of identifying superior alleles of strong culm genes in natural variants and pyramiding these genes for improving high yielding varieties with a superior lodging resistance.
