    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.

    PARTICULARITĂȚILE RĂSPUNSULUI GENOTIPURILOR DE TOMATE SUB ACȚIUNEA INFECȚIILOR VIRALE ȘI A DESCENDENȚILOR ACESTORA LA STRESUL ABIOTIC

    The evaluation of some polyvalent biochemical indicators under optimal conditions and heat or drought highlighted specific aspects if these plants came from parents infected with Tobacco Mosaic Virus (TMV) or Tomato Aspermy Virus (TAV). Thus, depending on the genotype, in both infected plants and their descendants, the POX values were usually higher or lower than the control group. The origin of the plants (control, TMV, TAV) had the largest contribution in the variability of H2O2 and stress for POX, respectively 74,1 and 23,6 %, and the combinations of the factors genotype, stress and origin had a considerable impact on the H2O2 content.
