Creation of new source material for beetroot breeding by the method of induced mutagenesis

Abstract

As a result of the carried-out work new mutant forms of beetroot, which have economically valuable traits - early maturing, narrow leaves, a small rosette of leaves were revealed. The roots of the studied varieties before planting in the field were irradiated with different doses: 150 Gy, 300 Gy, 500 Gy, 600 Gy. The roots of controlled crops were without irradiation. Mutant traits were observed on the plants as a whole or in the form of chimeras. In red beet varieties Prygazhunya after a half months of growth bimodal leaves and narrow leaves were observed. Morphological analysis of stomatal apparatus of various plants from generation M was allowed to reveal mutant form with deformed stomata in plants varieties of Vesta in the variant of irradiation with a dose of 300 Gy.
