BIOLOGICAL RESOURCES DIVISION: Identification of the low-tiller gene in rice (Oryza sativa L.)

摘要

The genetic mechanisms of low-tillering in two Japonica-type rices, Aikawa 1 and Shuho, were clarified and the controlling gene was identified on rice chromosomes using molecular markers. In these two Japonica varieties, the single dominant gene controlling low-tillering was confirmed on the basis of segregation analyses in each BC_1F_2 population derived from the crosses with Indica-type varieties IR64 and IR72 as recurrent parents, respectively.
