MAIN TRENDS IN OAT (Avena sativa L.) BREEDING AT THE INSTITUTE OF AGRICULTURE IN KARNOBAT, BULGARIA. I. WINTER OATS
Abstract
In the 1980s, under the influence of the worldwide breeding achievements, the Institute of Agriculture in Каrnobat launched its program for breeding new oat varieties. 80 % of the breeding program included winter oats, and 20 % - spring oats.The goal of these two main directions has been to create genotypes combining high and stable productive potential, high quality grain, complex resistance to stressful effects from abiotic and biotic environmental factors. It is necessary to make specialized collections, to create suitable source material, to adapt and apply new methods and approaches to assess the breeding material and to clarify some genetic and biological issues of theoretical and applied nature, which support the breeding process to realize the set goals. The priority areas in the breeding programs focus on overcoming low winter resistance, drought tolerance and productivity, reduction of the vegetation period, high stem and poor lodging resistance, increased grain quality, and others. Conventional, biotechnological, physiological and biochemical methods were used to evaluate the created genotypes.
