[Development of Dasypyrum genome specific marker by using wheat microsatellites].

One hundred and two SSR primer pairs, distributed in chromosome 1A to 7A, 1B to 7B, 1D to 7D of Triticum aestivum, were investigated on Dasypyrum breviaristatum, D.villosum, wheat-Dasypyrum amphiploids and its derivatives, with the control of common wheat Chinese Spring and elite wheat cultivars. A specific polymorphic DNA fragment of about 400 bp (415 bp-long by sequenced, named Xgwm301/415) amplified by primer pair Xgwm301 was obtained in all lines containing Dasypyrum chromosomes, but there were not the case in the tested common wheat.
