Abstract

Chromosomal locations of 10 isozyme loci in rice (Oryza sativa L.) were determined through trisomic analysis. All 10 genes produced altered allozyme banding patterns in specific F1 trisomics. This served as the primary source of evidence for chromosome locations ofEst-5, Icd-1, Acp-1, andPgd-1. The locations ofAmp-1, Amp-2, Amp-4, Pox-5, Got-1, andCat-1 were further confirmed from segregation data in BC1 generations, as the ratios deviated significantly from 1:1 in the critical trisomics but agreed with the expected trisomic ratios. Triallelic heterozygotes were recovered forAmp-1 andAmp-2. On the basis of these dataGot-1, Est-5, andIcd-1 were located to chromosome 1,Amp-1 to chromosome 2,Cat-1 andPox-5 to chromosome 3,Acp-1 to chromosome 6,Amp-2 andAmp-4 to chromosome 8, andPgd-1 to chromosome 11. BecauseAcp-2 andPox-2 are known to be linked withAcp-1, they must also be on chromosome 6. The gene order and recombination values between isozyme loci on chromosomes 3, 6, 8, and 11 are presented.
