VARIABILITY OF TRAITS OF INTERNODE LENGTH AND INTENSITY OF LATERAL SHOOT FORMATION IN TOMATO PLANTS
MILANIA MAKOVEI
Abstract:
The results of studying the nature of the manifestation of morphbiological traits of plants of different tomato genotypes controlled by mutant marker genes br and ls are presented. Genetic determinism of growth response, clearly reflecting the features of tomato plant architectonics, is shown. It was found that moderate growth of vegetative mass (short internodes, limited number of lateral shoots) with a lower response to the action of environmental conditions have lines in the genome of which two marker genes br and ls are present. Lines 183, 186, 196, 234, 237 and 10/16 combining short internodes with complete absence or single poorly developed reduced lateral shoots were selected for their use as donors in heterosis breeding in the process of creating F1 tomato hybrids with compact plant architectonics.
