摘要
Abstract
The Multi-tiller and dwarf mutant d63 was a spontaneous mutation of the twin-seedling progenies, which were derived from the cross between diploid SAR fl[ and Minghui 63. Compared with the wild type, the d63 mutant showed multiple abnormal phenotypes, such as dwarfism, more tillers, smaller flag leaf, reduced seed-setting rate and 1000-grain weight. Genetic analysis indicated that the mutant was controlled by a single recessive gene on chromosome 8. The gene was finally located on the short arm of chromosome 8, 0. 4 cM from RM22195, where 14 ORFs were predicted based on Rice Genome Annotation. Do3 might be a new gene as there was no dwarf genes reported on the short arm of chromosome 8.关键词
