我省皖南地区种植大豆历史悠久,长期以来经过自然选择和人工培育,创造出形形色色适于当地土壤、气候条件和耕作栽培制度的品种.这些大豆品种,由于受到当地特定自然条件的长期影响,形成了具有某些共同遗传性状的品种群,这些共同的遗传性状叫做生态性状;品种的生态性状是这群品种某些遗传性状和当地自然条件的综合反映.探讨皖南大豆生态性状的表现规律,对合理使用品种、制定育种目标及栽培措施都有一定的意义. 已搜集到的皖南大豆地方品种计139份,经初步归并同种异名品种,尚有110份.1974—1976年于合肥连续进行了观察、整理和研究,编写了品种目录,并对其生态性状获得一些认识,现简述如后. 一、几个生态性状与环境条件的关系(一) 生育期特性
Soybean cultivation in southern Anhui Province has a long history and has long been subject to natural selection and artificial cultivation to create a variety of varieties suitable for the local soil, climatic conditions and cultivation and cultivation system. These soybean varieties, due to the long-term impact of certain local natural conditions, The common genetic traits are called ecological traits, and the ecological traits of breeds are the comprehensive reflection of some hereditary traits and local natural conditions of these breeds.Explore the law of the ecological traits of soybean in southern Anhui, Reasonable use of varieties, the development of breeding objectives and cultivation measures have a certain significance.Has been collected in southern Anhui 139 local varieties of landrace, the initial classification of the same species of alien species, there are 110. 1974-1976 in Hefei continuous Observation, sorting and research, the preparation of the catalog of species, and some understanding of its ecological traits, are briefly described as follows. First, the relationship between several ecological traits and environmental conditions (A) characteristics of the growth period
