山东大豆种质资源耐盐性鉴定

Appraisal of Salt Tolerance of Soybean Germplasm in Shandong Province

１９８６～１９８９年鉴定了山东省７６０个大豆品种的耐盐性。从中筛选出芽期耐盐品种１４１份，苗期耐盐品种９０份，并筛选出２５个芽期和苗期均耐盐的大豆品种。不同大豆品种及同一品种不同生育期耐盐性不同，芽期与苗期耐盐性无明显关系；大多数耐盐品种来源于盐碱地和干旱少雨地区；耐盐品种一般植株较高，分枝较多，成熟偏晚，亚有限或无限结荚习性，籽粒较小，籽形椭圆或长（扁）椭圆形。

Salt tolerance of 760 samples of soybean germplasm in Shandong ProVince had been assaid from 1986 to1989, selecting out many varieties salt-tolerant at different stages, including 141 samples tolerant at germinating, 90 samples tolerant at seedling, and 25 samples tolerant both at germinatins and seedling. Salt tolerance varied atom varieties and developing stases. Salt-tolerant varieties mostly came from alkaline and drought areas, with higher plants, more branches, and smaller seed in ellipse or flat ellipse shape, having later maturing and determinately or indeterminately podding habit.
