大豆在我省栽培历史悠久。长期以来,经过不同地区不断地人为定向培育和选择,创造了适应各地区、不同自然环境条件和耕作制度的大豆品种类型。我省南北纬度相差4度(31°—35°),耕作制度极为复杂,因而品种类型较多。就已搜集到的本省大豆地方品种已达1332份(包括上海市60份,春大豆203份,其余都为夏豆),研究这些品种的生态特性,对大豆的栽培与育种工作,都具有极其重要的意义。
Soybean cultivation in our province has a long history. For a long time, through continuous human-oriented cultivation and selection in different regions, the soybean varieties that have adapted to different regions, different natural environment conditions and farming systems have been created. There is a difference of 4 degrees (31 ° -35 °) between south and north latitudes in our province, and the farming system is extremely complicated, so there are more varieties. Has collected 1332 local varieties of soybeans in our province (including 60 in Shanghai, 203 in spring soybeans and the rest in summer beans). The ecological characteristics of these varieties have been studied and their cultivation and breeding work have been extremely successful Significance.
