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 F(2) generation in rice, HCA1 and
HCA2
, was performed. HCA1 and
HCA2
are 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 F(2)
chlorosis
deduced from the location of the two genes was discussed. The possibility of the introgression of the chromosomal segments encompassing HCA1 and/or
HCA2
was also discussed from the viewpoint of Indica-Japonica differentiation.
