    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.

    STUDII ALE VARIABILITĂȚII ȘI HERITABILITĂȚII CARACTERELOR DE PRODUCTIVITATE ȘI CALITATE LA GRÂUL COMUN
    (CEP USM, 2024) Lupaşcu, Galina; Gavzer, Svetlana; Cristea, Nicolae; Rudacova, Angela; Cherdivară, Ala
    The article presents the results of the genetic-environmental control study of the productivity elements of the common autumn wheat spike (7 genotypes during the years 2020-2022). The objects of the work: i) recording the elements of productivity; ii) establishing the weight (%) of the year, genotype, year x genotype interaction factors of in the source of variability character; iii) calculation of genetic parameters of variability and heritability, heritability coefficient; iv) determination of the biochemical quality of wheat grains. Research methods: biometric, biochemical, mathematical, statistical. Results obtained - the particularities were established: i) variability, heritability, the factorial weight of the conditions of the year and the wheat genotype in the source of variation of the productivity elements of the spike; ii) heritability and genetic advance; iii) the content of proteins, wet gluten, dry gluten, carbohydrates in grains during the years of study.
