    HERITABILITATEA UNOR CARACTERE AGROMORFOLOGICE LA COMBINAȚIILE HIBRIDE DE ORZ DE TOAMNĂ ÎN DIFERITE CONDIȚII DE AN
    (CEP USM, 2024) Grigorov, Tatiana; Andronic, Larisa; Smerea, Svetlana
    The aim of our research was to estimate the heritability (h2,%) and genetic advantage (GA, %) of agro-morphological traits of winter barley hybrids forms (Strălucitor x Igri and Ciuluc x Igri) under different years conditions. Evaluation of genotypic variance components reveals high value of h2 (>60%) associated with high (>20%) and moderate GA, % (10-20%) for important traits (plant height, spike length, apical internode length, number of spikelets and ker-plant height, spike length, apical internode length, number of spikelets and ker-number of spikelets and ker-spikelets and kernel per spike, productive tillers per plant, thousand kernel weight) in the 8 productive two-rowed and four-rowed selected hybrids forms. This reflects additive effects in the inheritance of traits, a fact that allowed the efficient selection of interest forms with the potential for use in the further breeding work of winter barley.

    PARTICULARITĂȚILE RĂSPUNSULUI GENOTIPURILOR DE TOMATE SUB ACȚIUNEA INFECȚIILOR VIRALE ȘI A DESCENDENȚILOR ACESTORA LA STRESUL ABIOTIC
    (CEP USM, 2023) Mării, Liliana; Andronic, Larisa; Smerea, Svetlana; Rudacova, Angela; Cherdivară, Ala; Rudacov, S.; Sahanovschih, Marionela
    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.
