    Rolul variabilității genetice în interacțiunea grâului cu Alternaria alternata
    (CEP USM, 2024) Lupaşcu, Galina; Cristea, Nicolae; Gavzer, Svetlana
    The article presents data on the reaction of 10 common winter wheat genotypes to culture filtrates of Alternaria alternata isolates. Through factorial analysis, the role of wheat genotype (42.2 ... 51.1%) in the source of variation in radicle length, stem length, seedling length was found. The A. alternata isolate factor presented a higher weight for germination (48.9%) and vigor index (49.0%). The association of the high level of the coefficient of heritability with the advanced genetic progress shows that in the control of growth and development characters additive factors are involved.

    Variabilitatea atacului bolilor foliare la forme de perspectivă de grâu comun
    (CEP USM, 2024) Cristea, Nicolae; Gavzer, Svetlana; Lupașcu, Galina
    The aim of the present research was to establish the attack characteristics of foliar diseases (septoriosis, brown rust, yellow rust, powdery mildew) in 25 prospective genotypes of common winter wheat in years with different climatic conditions (2023, 2024). It was found: i) the strong dependence of the disease of wheat plants on climatic factors (the intensity of yellow rust in 2023 and of powdery mildew in 2024); ii) significant variability in susceptibility of wheat populations / genotypes. Common winter wheat populations/lines with reduced complex disease susceptibility have been identified, that can be implemented in breeding programs.
