AbstractF2 progeny from crosses between twenty-seven translocations and eleven genetic characters of Sorghum bicolor (L.) Moench were studied to demonstrate the use and limitations of translocations in mapping genes on chromosomes in this species. A summary of results from 1976 to 1989 is reported using temporary chromosome designation letters A to J. Recombination was estimated between translocation breakpoints and loci for six simply inherited traits. Inferences from linkage data indicate Zbzb to be located on chromosome F; Slsl on chromosome B; Yy (and linkage group 4) on chromosome J; Lglg and Pp (and linkage group 2) on chromosome C; and Bm0, on either A or B. Semisterility of three translocations was found to be linked with genes from two different linkage groups: T-16(FJ) with both Zbzb and Yy; 9157 (BF) with both Zbzb and Slsl; and T-10(CB) with genes Lglg, Pp and Slsl.
