Popis:	Many postzygotic reproductive barrier forms have been reported in plants: hybrid weakness, hybrid necrosis, and hybrid chlorosis. In this study, linkage analysis of the genes causing hybrid chlorosis in F2generation in rice,HCA1andHCA2, was performed.HCA1andHCA2are located respectively on the distal regions of the short arms of chromosomes 12 and 11. These regions are known to be highly conserved as a duplicated chromosomal segment. The molecular mechanism causing F2chlorosis deduced from the location of the two genes was discussed. The possibility of the introgression of the chromosomal segments encompassingHCA1and/orHCA2was also discussed from the viewpoint of Indica-Japonica differentiation.
