    Evaluation of variability of quantitative characters in SC4 triticale somaclones with valuable agronomic properties [Articol]
    (Editura USM, 2025) Ciobanu, Renata
    As a result of research on the influence of in vitro culture and gamma radiation on quantitative traits, significant variations in the coefficient of variation values were observed in SC4 triticale somaclones. Both in vitro culture and radiation caused changes in the coefficient of variation of quantitative traits in the studied genotypes, compared to the control. The variability assessment revealed low to medium variation, indicating individual similarity across the studied traits. Radiation showed a major action on the following traits: length of the last internode, plant height and number of fertile siblings. The factors studied represent a significant source of variation, with their influence intensified by the specific characteristics of the genotype.

    Ariabilitatea productivităţii la somaclonele SC1-SC2 de triticale obţinute prin cultura in vitro şi iradierii cu raze gama
    (CEP USM, 2024-10-07) Ciobanu, Renata
    As a result of research on the influence of in vitro culture and gamma radiation on the expression of traits such as the number of grains per ear, grain weight, and the mass of 1000 grains, significant variation in the values of the coefficient of variation was observed in somaclones from three generations of triticale. Both in vitro culture and radiation caused changes in the coefficient of variation of quantitative traits in the studied genotypes, compared to the control. Maximum effect is induced by gamma radiation in the first generation (SC1) for all traits, with a substantial decrease in the third generation (SC3). The factors studied represent a significant source of variation, with the influence being intensified by the specific characteristics of the genotype.
