Gametophytic Selection in Rice

  • Yo-Ichiro Sato
Conference paper


Asian cultivated rice (Oryza sativa) and its wild relatives (O.rufipogon) are differentiated into sub-species (O. sativa indica andjaponica), and ecogeographic races, respectively. Between those subspecies or races, and between those species and related taxa of AA genome, various reproductive barriers have been reported, a part of which are caused by gametophytic selection. Genetical and physiological studies on the gametophytic selection may thus provide a deep comprehension of its role for the reproductive isolation between and within those species of rice.
