Chromosomal localization of five mutant genes in rice, Oryza sativa, using primary trisomics uri icon

abstract

  • The chromosomal locations of five mutant genes in rice were determined by crossing the marker stocks with the 12 primary trisomics. Genetic segregation of each gene was studied in the F-2 or backcross populations. Out of the 60 possible cross combinations, 43 F-2 or BC1 populations were studied. Segregation data indicated that spl11 was located on chromosome 12 while wp2 and eg2((t)) were located on chromosome 6. The genes v12((t)) and Bc6 were located on chromosomes 8 and 9, respectively, which are sparsely populated with genetic markers.
