摘要
The discovery of germplasmic resources of PGMS and TGMS rices has opened a new avenue for the exploitation of rice heterosis by two-line method. Meanwhile, the two kinds of germplasmic resources have provided important materials for the studies of physiological genetics as well as developmental genetics. PGMS and TGMS lines possess the distinct trait of fertility transformation. However, up to now no convincing reports have been published with respect to the relationship between the morphological
