MARKER TRAITS AND THEIR MANIFESTATION IN THE EARLY STAGES OF TOMATO PLANT DEVELOPMENT
MAKOVEI MILANIA DUMITRU
Abstract:
The article presents the results of the assessment of the phenotypic expression of mutant marker genes controlling anthocyanin synthesis and the degree of distortion of the shape, color, and first true leaves in tomatoes. Mutant forms (125 genotypes) are classified into groups depending on the nature of manifestation and the degree of phenotypic expression of traits depending on the genotype (single- and multi-marker mutants) and plant growing conditions (field, greenhouse). It has been shown that a higher degree of trait variability is characteristic of multi-marker mutant forms. Single- and multi-marker mutants have been identified in which the marker traits controlled by the genes afl, apn, atv, aut, c, cy, cla, clau Cu, div, ga, inta, Ln, ltf, lur, lut, l-2, nv, Tor Wom, yg-2, are phenotypically clearly manifested and easily identified under different growing conditions of their plants (V = 2.4...8.3%).
