Abstract:
An extensive collection of wild emmer was screened for yellow rust resistance in a joint project by research institutes in Israel and The Netherlands. In inoculation experiments performed both in seedling stage and at maturity, the wild emmer accessions displayed a diversity of responses to yellow rust infection, ranging from immunity to complete susceptibility. Selection Triticum dicoccoides var. aaronsohni G-25 was most promising proving highly resistant to all 21 races and field races used. Selection G-7, which was also very resistant in the trials, differed slightly from G-25 in infection types produced on inoculation with one of the isolates; this may be an indication that the genetic factors controlling resistance in these two selections are not identical. It is concluded that the diversified populations of wild emmer indigenous to Israel possess genes which confer high resistance to a very wide spectrum of yellow rust races, including all common races in Western Europe and the Middle East. As resistance factors can be transferred easily from T. dicoccoides to durum and common wheat, this source may be utilized in producing varieties of cultivated wheat with improved yellow rust resistance. © 1970 Kluwer Academic Publisher.
