Abstract
În condiţiile zonei de nord și sud a Republicii Moldova pe parcursul anilor 2020-2021
s-a efectuat evaluarea unor hibrizi comerciali de floarea-soarelui cu diferită proveniență în scopul selectării hibrizilor cu caractere valoroase ca surse suplimentare pentru intensificarea producției de floarea-soarelui în țară. S-a stabilit că hibrizii testaţi au prezentat după trăsăturile morfologice o variabilitate bogată, care în mare măsură este dependentă de genotip, proveniența acestuia și totodată condițiile climatice zonale și anuale. Lucrarea de față include date privind evaluarea potenţialului genetic la 6 hibrizi de floarea-soarelui după unele caractere cantitative (indicele suprafeței foliare, suprafața foliară, cantitatea de clorofila a și b, cantitatea de carotenoizi, înălţimea plantei, numărul de frunze, recolta medie, conținutul de ulei) şi markeri moleculari (RAPD).
The evaluation of some commercial sunflower hybrids with different origins in the conditions of the northern and southern areas of the Republic of Moldova was conducted during the years 2020-2021 in order to select the hybrids having valuable traits as additional sources for intensification of sunflower production in the country. It was established that the tested hybrids have a rich variability based on the morphological traits, which is largely dependent on the genotype, its origin and also the zonal and annual climatic conditions. The present article includes the data on the genetic potential evaluation of 6 sunflower hybrids obtained by means of some quantitative traits (leaf area index, leaf surface, amount of chlorophyll a and b, amount of carotenoids, plant height, number of leaves, average yield, oil content) and molecular markers (RAPD).
