| Abstract: | Root-knot nematode is a significant root-parasite of common wheat. A dominant gene Rkn-mnl for resistance was transferred into wheat from Acgilops variabilis. This gene was shown to be on chromosome 3B. Further analysis indicated that it is on the long arm of this chromosome and independent of the centromere. |
