ADAPTIVE POTENTIAL OF THE GENE POOL OF LEAF LETTUCE, CREATED BY THE METHOD OF INDUCED MUTAGENESIS ON THE BASIS OF THE DOMESTIC CULTIVAR VELMOZHA
Journal Title: Наукові доповіді НУБіП України - Year 2018, Vol 2, Issue 2
Abstract
Created domestic varieties of leaf lettuce in temperate climates (10-15 years later) unfortunately, in modern conditions of climate change has partially lost its test characteristics and does not meet for the modern agricultural production requirements. That is why, the main purpose of the research was to create a highly adaptive source material for the highly adaptive breeding of these vegetable plants. Methods. Object of research: leaf lettuce (Lactuca sativa L. var. secalina). Subject of research: 16 mutant samples of lettuce progeny M2- M4, created by the method of chemical and physical mutagenesis on the basis of the variety of domestic breeding Velmozha. The research was conducted in accordance with the method of VIR for the study of collections of infrequent cultures, according to the working plans according to the current standards.Results. As a result of 3 years of research (2012-2014), two perspective mutant samples of the generation M4 were identified for the production of intensive cultivars of varieties, which demonstrated a sensitive reaction to the influence of external growing conditions, yields 11,1-12,7 t/ha , which is higher than the original form at 43,0-68,8 %. Discussions. The created mutant gene pool is a valuable starting material for the selection of leaf lettuce, namely, for the creation of ecologically-plastic varieties, and varieties of intensive type of cultivation.
