为了获得可持续性的农业饲料作物产量,发展多样的能够将高产的生态稳定性相结合的饲料作物是非常必要的。保加利亚的多年生草原育种工作,已经有49年之久,尤其是在普列文的饲料作物研究所。繁殖计划的目标是开发新的多年生草品种饲料和产量高的种子,高饲料质量和高适应性的牧场,提高干草和景观的利用率。于1966-2015期间,收集并研究了普列文大量的寒冷和温暖的气候常年饲料草饲料作物研究所的初始育种材料(当地人口和引进品种)。植物生物多样性的新形式和品种是应用传统和现代育种方法有目的地有效选择通过生产力和自适应性,生态基因分析量化特征,多倍化,以及种间杂交。2007年,梅勒尔贝克在比利时遗传和育种研究所提出倍性水平,样本通过Partec细胞分析仪CA-II和软件DPAC(德国明斯特)进行分析。荧光发射强度与DNA数量呈线性相关,此实验获得了直方图。在这几年当中,六种不同的多年地生草类物种已经演变成:鸭茅、无芒雀麦、尼卡、高羊茅、阿乐贝纳、多年生黑麦草、冰草和摩拉瓦洒,并根据CPVO(2011)和UPOV(2006)对新品种的技术准则进行了描述。这些多年生牧草品种有许多有价值的特性,例如有非常高的饲料价值和种子生产效率,具有持续性、胁迫耐受性、牧草优质,可以利用其不同的方向和倍性水平。饲料作物研究所保持注册品种和生产基础种子。
In order to obtain sustainable agricultural feed crop yields, it is imperative to develop diverse feed crops that combine high ecological stability. The perennial grassland breeding work in Bulgaria has been 49 years, especially at Pleven’s Feed Crops Institute. The goal of the breeding program is to develop new perennial grass feed and high-yielding seeds, high feed quality and high-adaptability pastures to improve hay and landscape utilization. During the period 1966-2015, the initial breeding material (native population and introduced species) of Plena, a large number of cold and warm climate perennial forages and feed crop institutes, was collected and studied. New forms and varieties of plant biodiversity are purposefully and effectively selected using both traditional and modern breeding methods through productivity and adaptability, quantitative analysis of ecological genes, polyploidization, and interspecific hybridization. In 2007, Mellbeek proposed a ploidy at the Belgian Institute of Genetics and Breeding, which was analyzed by the Partec Cell Analyzer CA-II and the software DPAC (Münster, Germany). Fluorescence emission intensity and the number of DNA was linearly correlated, the experiment obtained a histogram. During these years, six different perennial grassy species have evolved: Dactylis glomerata, Bromus inermis, Nicca, Tall Fescue, Aruba, perennial ryegrass, Agrimony and Morava Sprinkled, and the technical guidelines for the new breed were described in accordance with CPVO (2011) and UPOV (2006). These perennial forage varieties have many valuable properties, such as very high feed value and seed production efficiency, persistence, stress tolerance, forage quality and utilization of different orientations and ploidy levels. Feed Crop Research Institute maintains registered varieties and produces basic seeds.
