品种在植物栽培学中似乎已起了科学技术进步的载体作用,在增强集约化生产条件中将起着巨大的作用。在新品种生产中迅速地研究和推广具有较高生产效力和优良品质的杂交种是十分重要的任务,按照新的工业技术操作培育这类品种有较大的可塑性和适应性。由于广泛的和目标明确的工作,每年实际推广的品种和杂交种都有很好的生物特性和经济特性,而且是经过测试中心和品种保持中心深入研究和权威性鉴定过的。近30年来保加利亚已选育出了4～5倍的小麦、大麦和玉米的更新品种,2～4倍的甜菜、菜豆、马铃薯、番茄和其他作物的品种。在近二三年中,以下品种和杂交种可作为正式
Varieties seem to have played a role as carriers of scientific and technological progress in plant cultivation and will play a huge role in enhancing intensified production conditions. It is a very important task to rapidly research and popularize hybrids with high production efficiency and good quality in the production of new varieties. It is more malleable and adaptable to cultivate these varieties according to the new industrial technology. Due to a wide range of well-targeted work, the varieties and hybrids actually promoted each year have good biological and economic properties and are thoroughly researched and authoritatively identified by the Testing Center and the Variety Preserving Center. Bulgaria has bred 4 to 5 times more recent wheat, barley and maize, 2 to 4 times more beets, beans, potatoes, tomatoes and other crops for nearly 30 years. In the past two or three years, the following varieties and hybrids can be used as formal
