Plant type improvement plays an important role in breeding of new rice varieties with high yield and good quality. A recombinant inbred lines (RIL) population, constructed by crossing Liaojing 5, the most representative rice cultivar with erect panicle type in Northeast China with Akita Komachi, the Japanese famous good quality rice variety with curved panicle type, were used as test material to investigate the variations in plant type traits in the progeny and their mutual relationship. The results showed that there was remarkable separation in plant type traits among RIL population, most of plant type traits accorded with inheritance of quantitative traits controlled by multi genes.These plant type traits could be recombined in the progeny, but the correlation between different plant type characters significantly differed. Similar to Akita Komachi, the RILs with higher plant height always characterized by long panicle, large panicle curvature, small leaf width, few number of branches, low grain density. However, the RILs with dwarf plant height tended to have short panicle, small panicle curvature, large leaf width, large number of branches, large grain density, similar to Liaojing 5. This phenomenon was related to some genes pleiotropy or linkage which controlled some plant type traits. Despite the low probability, the typical plant type characters of Chinese rice varieties and Japanese rice varieties could be combined with each other. Breeders could create new varieties with comprehensive characteristics of plant type through hybridization and direct selection, such as long-flag-leaf and short-dense-panicle type or dwarf and long panicle type.
