title: [Inheritance of stability of MN81330 common wheat samples to septoria blotch].
abstract: Wheat samples described in literature as resistant to septoria glume blotch were assessed for their response to inoculation with Septoria nodorum Berk. Three days after inoculation with the infectious agent, samples Klein Titan (k-41772), Mian Jang (k-61568), Walter (k-54585), Reisler (k-59505), Rempart (k-59493), PIN/BOW (k-62838), MN81330 (k-60785), Frondoso (k-46736), Sokrates (k-58179) were classified as resistant to infection. Seven days after inoculation, only samples Reisler and Mian Jang were regarded as resistant. The genetic control of glume blotch resistance was studied by hybridological analysis in sample MN81330. Resistance of this sample manifested in a longer latent period of the disease is controlled by two dominant complementary genes not linked to the gene Lr24 responsible for resistance to brown rust, to the gene responsible for coleoptile coloration, and to minor genes that improve expression of the major ones.
