Ac. Sanchez et Gs. Khush, Chromosomal localization of five mutant genes in rice, Oryza sativa, usingprimary trisomics, PLANT BREED, 119(1), 2000, pp. 84-86
The chromosomal locations of five mutant genes in rice were determined by c
rossing the marker stocks with the 12 primary trisomics. Genetic segregatio
n 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. Seg
regation data indicated that spl11 was located on chromosome 12 while wp2 a
nd eg2((t)) were located on chromosome 6. The genes v12((t)) and Bc6 were l
ocated on chromosomes 8 and 9, respectively, which are sparsely populated w
ith genetic markers.
