Abordări metodologice de sporire a diversităţii în soluţionarea subiectelor din genetica şi ameliorarea plantelor

Abstract

The classical methodological approaches proposed for solving the objectives of the sub-program „Genetic and biotechnological approaches to the agroecosystems management under climate change” are argued through the prism of the modern methods of inducing genetic variability. To study the functionality of species/genotypes in dependence of environmental conditions it is proposed multivalent genetic, biotechnological, physiological techniques, aimed to develop measures to ensure the sustainability of agrosystems in the conditions of unfavorable environmental factors fluctuation (water restrictions, high temperatures) of crops genotypes with economic interest (winter barley, common wheat, corn, sunflower, tomato, as well as perennials, such as plum and apple). In this order is proposed the methods of inducing genetic variability through physical mutagenesis (ionizing radiation), cellular biotechnologies (gametic selection, in vitro culture of embryos, anthers). The proposed strategies will allow to obtaining and selecting genotypes of autumn barley, common wheat, corn, sunflower with ecological plasticity to ensure the sustainability of agrosystems.
