A close linkage is shown in barley between a gene for resistance to race 1 and 2 of Heterodera avenae (Ha2) and lack of purple colour at nodes, ligules and awns (pau). A number of recombination values between genes are given and a likely order is suggested for the following genes: Ha2, pau, cer g 10 , v and e, and the translocation break T 2–3 f. A survey is given of the varieties used and the problems encountered are briefly outlined. The importance for plant breeding is discussed.
