N2 - Understanding the association between nucleotide changes and phenotypic changes is necessary for germplasm enhancement but has been a significant challenge in the molecular genetics and breeding of rice. In this article, we summarize our efforts to develop plant materials such as chromosome segment substitution lines to enhance the genetic analysis of traits of interest. The power of genetic dissection of phenotypic traits by use of novel populations is illustrated by our genetic analysis of heading date. We also present examples of the discovery of useful alleles involved in disease resistance and drought avoidance. Finally, we describe the discovery of genome-wide single-nucleotide polymorphism, which facilitate genetic analysis. This new type of genetic marker has allowed us to uncover the genome architecture of modern cultivars in Japan. These areas of progress will gradually change the landscape of selection in rice breeding.
