甘薯品种在一个区域内,由于受特殊自然条件、耕作制度的长期影响,形成具有一些共同遗传性状的品种羣,就叫做品种生态型。品种生态型是这羣品种某些遗传特性和该区域自然条件的综合反映。本省甘薯地方品种是在一定的自然条件下,通过长期的自然选择及人工选择而形成的,它对于当地的自然环境、耕作制度具有良好的适应性。了解本省不同区域地方品种及性状的分布、改良品种在不同区域的适应特性及其对自然环境的反应,就便于明确品种的生态类型,从而为本省甘薯育种和栽培提供若干依据。为此,作者收集了本省各地多年来的品种试验资料,并先后分赴阜阳、临泉、宿县、滁县、安庆和屯溪等地进行调查访问,对本省甘薯品种的生态特性获得了一些看法,提出来供研究参考。
Sweet potato varieties in a region, due to the special natural conditions, the long-term farming system, the formation of a group of common genetic traits breeds, called the ecotype. The ecotypes of the breeds are a combination of some of the genetic traits of the breeds and the natural conditions in the region. Local sweet potato varieties are under certain natural conditions, through long-term natural selection and artificial selection formed, it has a good adaptability to the local natural environment and farming system. Understanding the distribution of local breeds and traits in different regions of the province, improving the adaptation characteristics of different breeds in different regions and their responses to the natural environment facilitate the identification of the ecological types of breeds and provide some basis for the breeding and cultivation of sweet potatoes in the province. To this end, the author collected information on varieties of cultivars from different parts of the province for many years and went to Fuyang, Linquan, Suxian, Chu County, Anqing and Tunxi for investigation and interview, obtaining ecological characteristics of sweet potato varieties in this province View, put forward for research reference.
