抄録

The chromosomal locations of glutamate oxaloacetate transaminase gene loci in Japanese bunching onion (Allium fistulosum L., 2n=2X= 16, FF) and shallot (A. cepa L. Aggregatum group, 2n=2X = l6, AA) were investigated using alien monosomic addition lines (2n=2X+1=17, FF+nA, AA+nF) and hypoallotriploid lines (2n=3X-1=23, AFF-nA, AAF-nF) between these two species. The gene locus Got-2 was located on the homoeologous sub-telocentric chromosomes, 6F in A. fistulosum and 6A in A. cepa Aggregatum group. The gene locus Got-1 was on the other chromosomes. The present results indicate that chromosomal locations of these gene loci, at least Got-2, were conservative both in A. fistulosum and A. cepa Aggregatum group during speciation and subsequent evolution.<br>
