    In the agrarian sector, lines, varieties, which had high uniformity, distinctiveness and stability of fruit productivity and quality in different environmental conditions, were of particular importance. The most important trend in the strategy of plant breeding at the stage of adaptive intensification in agriculture was combining the resistance of the varieties to the stress- producing abiotic factors of the environment with high levels of fruit productivity and quality. The determination of the genetic complex of quantitative characters, including drought resistance, hindered the success of the breeding process, the purpose of which was to create genotypes combining many valuable characters. As a result of distance hybridization, interest for the breeder also presents the spectrum of genetic variability, which increases the efficiency of genotypes selection with high productivity and increased resistance to environmental stressors. One of the main tasks of amelioration was grandiose blending in the same variety of high productivity and resistance to stress factors (drought).

    LINII DE PERSPECTIVĂ PENTRU OBȚINEREA SOIURILOR DE TOMATE CU REZISTENȚĂ SPORITĂ LA AGENȚII PATOGENI
    (CEP USM, 2023) Sîromeatnicov, Iulia; Cotenco, Eugenia; Paladi, Dana
    The investigated researches were oriented towards studying the dynamics of development and evolution of diseases in tomato culture with the assessment of resistance comparative of plants to pathogens visualized in field conditions (Alternaria sp.; Stolbur disease mycoplasma and Tomato mosaic virus (TMV). The research results show us that the effects caused by the disease Alternaria sp., in tomato lines cultured by seedlings were contaminated with the percentage value of 68,7%, at the same time for the parental forms cultured by seeds this disease constituted maximum values of 89.1%. The difference between perspective lines and parental forms is 20.4%. The maximum size of the values obtained in parental forms exceeds by 21.6% the outlook lines for the Stolbur disease mycoplasma.
