摘要
1987—1989年在神农架及三峡地区进行大豆品种资源考察,搜集栽培大豆地方品种516份。本区栽培大豆品种资源丰富,分布广泛,垂直分布上限达海拔1950m。这批资源具有蛋白质含量较高、进化程度不一致、早熟性较好、植株性状变幅大、适应性强等特点。发现了一些具有高蛋白、极大粒、早熟矮秆、多荚、多分枝、丰产等特性的优良资源。
Soybean germplasm resource expedition was made to Shen-nongjia and Sanxia Region from 1987 to 1989.516 cultivated local soybean varieties were collected during the expedition.Results showed that this region possessed rich soybean germplasm resources with an extensive distribution.Vertical distribution reached an altitude of 1950 meters above sea level.They had the characteristics of high-protein conetnt,different evolution degree,early maturity,good adaptability.Some rare materials,such as germplasm with kidney-shaped long seed,were collected.Some extraordinary materials with early maturty,short stalk,very big seed,high-protein content,more pods and more branches per plant were found through screening.
