Summary

A number og wheat varieties from NordGen and Allkorn were tested fro susceptibility to common bunt. Most were susceptible to common bunt which is in line with other screening experiments of randomly selected varieties. However, a few lines not previously known to be resistant were shown to have different resistance genes. None of them however were resistant to all the virulence races tested. NILs developed by MacKey were evaluated and there seem to be a potential for using some of them as differential lines for resistance gene Bt1, Bt5, and Bt9. Purification based on resistant head rows may also develop NILs with resistance to Bt6 and Bt10 and possible also Bt7 from NGB16160. A crossing program of the remaining Bt-genes was started in 2016. The NILs may be used also to support development of genetic markers of the resistance genes.
