Abstract
Lines of wheat with the 6M(v) chromosome from Aegilops ventricosa disp lay partial resistance to both pathotypes Ha12 and Ha41 of Heterodera avenae. With either pathotype, the effect of this alien chromosome on cyst production, size, and fecundity was expressed in resistance tests . Partial resistance of five 6M(v)(6D) substitution lines varied accor ding to the intrinsic cyst-forming capacity of the nematode pathotypes and the recipient germplasms. Such partial resistance can be utilized in wheat breeding lines for integrated management of the cereal cyst nematode.
