    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.

    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.
