dc.descriptionA hybrid weakness phenomenon is controlled by a set of complementary genes, Hwc1 (hybrid weakness c) and Hwc2, in rice. The Hwc2 gene is prevalent among temperate Japonica but not among tropical Japonica or Indica. In this study, the chromosomal location of the Hwc2 locus was determined from the segregation in the F1 hybrids made between 127 recombinant inbred lines and the cultivar ‘Jamaica’. Hwc2 was located between the two restriction fragment length polymorphism loci, XNpb264 and XNpb197 on chromosome 4. Further analysis indicated that Hwc2 was closely linked to Ph (phenol staining). The genetic and phylogenetic significance of the Hwc2 locus and the surrounding chromosomal region is discussed.
