THE MODERN CHALLENGES AND OPPORTUNITIES FOR IMPROVING THE GENETIC DIVERSITY OF TOMATOES

 


Milania MAKOVEI1

Abstract. This article designated modern climatic and genetic factors as causes of the intensification of genetic erosion in tomatoes (Solanum lycopersicum L). The possibility of expanding the genetic diversity of tomatoes through the use of mutant genes in breeding that control a wide range of economically valuable traits is being considered. The potential of mutant forms as a source of resistance to abiotic stress factors (high and low temperatures, drought) for use in breeding as donors is demonstrated. A description is provided of the phenotypic expression of mutant genes controlling plant habit and architecture, which determine the expression of various fruit traits, including resistance to the most common diseases. The possibility of using certain mutant genes to expand the range of recombinational variability in F2 populations and to obtain transgressive tomato forms with a completely new combination of mutant marker and economically valuable traits is demonstrated.

Keywords: Tomato (Solanum lycopersicum L.), climatic and genetic factors, mutant genes, selection, genetic diversity.
