“…Sharma et al (1997b) reported that substitution line P29 was resistant to BYDV but susceptible to four cultures of powdery mildew. Genes for resistance to Hessian fly (Mayetiola destructor Say) [Diptera: Cecidomyiidae] biotype L and BYDV were also found to be on different chromosomes of T. intermedium (Sharma et al 1992(Sharma et al , 1997b. This is consistent with the present finding that these resistances are not carried in a linkage block in T. intermedium.…”

Wheat (Triticumaestivum) relatives are sources of useful genes for disease resistance. Chromosomally segregating populations of intergeneric hybrids between wheat and its distantly related species provide opportunity to study and introgress multiple disease resistance. While introgressing resistance to barley yellow dwarf virus (BYDV) from Thinopyrum into wheat, which is susceptible to BYDV, we scored powdery mildew (Erysiphaegraminis) and leaf rust (Pucciniatriticina) resistance, and chromosome numbers in second and third backcrosses (BC2 and BC3) of intergeneric hybrids of wheat with Thinopyrum ponticum and Thinopyrumintermedium. The frequency of multiple resistance to all the three diseases was low or became low when selection was applied for BYDV resistance and low chromosome numbers. Selection for fewer alien chromosomes while maintaining BYDV resistance was more effective in wheat x T. intermedium than in the wheat x T. ponticum cross. Mean chromosome numbers were significantly different in BC3 generation between BYDV resistant and susceptible plants in both crosses. Significant negative correlations between chromosome numbers and enzyme-linked immunosorbent assay (ELISA) values showed that as the critical Thinopyrum chromosome(s) were eliminated, susceptibility to BYDV increased. Results indicated that it is unlikely that genes for full resistance to all three diseases can be transferred simultaneously from Thinopyrum to wheat.Les espèces proches du blé (Triticumaestivum) sont à l’origine de gènes utiles pour la résistance aux maladies. Les populations à ségrégation chromosomique d’hybrides intergénériques entre le blé et des espèces peu apparentées nous offrent la chance de procéder à l’étude et à l’introgression de la multirésistance aux maladies. Alors que nous introgressions la résistance au virus de la jaunisse nanisante de l’orge (BYDV) de Thinopyrum dans le blé, qui est sensible au BYDV, nous avons coté la résistance à l’oïdium (Erysiphaegraminis) et à la rouille des feuilles (Pucciniatriticina), et compté le nombre de chromosomes dans les deuxième et troisième rétrocroisements (BC2 et BC3) d’hybrides intergénériques entre le blé et le Thinopyrum ponticum ou le Thinopyrumintermedium. Le taux de multirésistance aux trois maladies était bas ou est devenu bas lorsqu’une sélection a été faite pour la résistance au BYDV et pour un faible nombre de chromosomes. La sélection pour un plus faible nombre de chromosomes étrangers tout en maintenant la résistance au BYDV a été plus efficace pour le croisement de blé x T. intermedium que pour celui de blé x T. ponticum. À la génération du BC3, pour les deux croisements, le nombre moyen de chromosomes était significativement différent entre les plantes résistantes et celles sensibles au BYDV. Des corrélations négatives significatives entre le nombre de chromosomes et les valeurs du test immunoenzymatique ELISA ont démontré qu’à mesure que le ou les chromosomes déterminants du Thinopyrum étaient éliminés, la sensibilité au BYDV augmentait. Les résultats montrent q...

Hessian fly (Mayetiola destructor) is a serious pest of wheat (Triticum spp.) and of the reported biotypes of Hessian fly, biotype L is described as the most virulent. Inheritance of resistance to Hessian fly biotype L was investigated in crosses of a resistant accession of Triticum monococcum, and two susceptible accessions of T. monococcum and one susceptible accession of T. boeoticum, all diploid wheats. F2 and testeross (backeross) families were classified for reaction to Hessian fly in the seedling stage and analysed by Chi-square goodness-of-fit tests for genetic segregation ratios of resistant or segregating families to susceptible families. Resistance was found to be simply inherited, controlled by one or two genes. This is the first report on the inheritance of resistance to Hessian fly in A-genome diploid wheats, and simple genetic control indicates possibility of transfer of this trait to cultivated wheats.

Mots-des : Aegilops squarrosa -analyse meiotique -croisements interspecifiques -Mayetiola destructor (Say) -Triticum durum.Abstract.-Hessian fly (Mayetiola destructor (Say) is probably the most serious pest on wheat crops (Triticum sp.) in many countries. Interspecific crosses were carried out between durum wheat cultivars and different Ae. squarrosa accessions that are resistant to the Hessian fly. The low viability and the sterility of the interspecific hybrids F 1 and its progenies 1st, 2nd and 3rd generations have a determinant impact on seed set and percentages of the interspecific hybrid produced. The rate of univalent percentages decreased clearly in the second generation, in connection with spontaneous chromosomal doubling. Most interspecific offspring were resistant to the Hessian fly. At F 4 and F 5 they still showed a segregation of resistance. Few interspecific progenies showed higher resistance, especially at the 5th generation.
