The results of the tests of new tomato standard varieties in conditions of Republic of Dagestan

Ten standard  varieties, differing in the length of the stem were chosen in breeding and collector's gene pool of tomato. The aim was to study the experience of morphological and biological indicators of data, as well as donors and economically valuable traits for their further use in breeding of tomato. When examining samples the special attention was paid  to such factors as the length of main stem, number of leaves on the main stem, number of flowers in a third brush number of side stems, stem diameter at the base, the diameter of the stem above the third leaf.  After three years of experiments in studying the morphological and biological indicators of standard tomato varieties prospective donors have been allocated: Torpedo, Gigantskaya Rosa, L20/11, Phonarik. These varieties characterize by a unique combination of agronomic characteristics and can be used as a parent form to obtain high-value hybrid.
