摘    要:对97份河北省大豆地方品种在2个磷梯度下的苗期耐低磷特性分析表明,植株总生物量、地下部生物量、地上部生物量、地下部磷含量、地上部磷含量、总磷含量和根冠比7个指标的相对值存在较大的基因型差异.经相关分析和逐步回归分析发现,相对总生物量和总磷含量与其它指标问存在显著相关关系,二者比值(植株磷效率)可作为磷胁迫下耐低磷大豆品种的筛选指标.以相对植株磷效率为指标进行聚类分析,将材料分为耐低磷、中间类型和不耐低磷3类,并筛选出"皮狐狸"和"本地黑"2个高耐低磷大豆品种.

关 键 词:大豆  品种资源  耐低磷  种质筛选

Abstract:In China,soil area with phosphorus lack has reached 151.3 thousand ha,and more than 75% of soil in Hebei growing-areas is short of phosphorus.Soybean needs high phosphorus contents,especially,in seedling stage.Excessive usage of phosphate fertilizer,will aggravate shortage of P resources,destroy entironment and block the sustainable agriculture development.Landraces with better gene which can be used by people are provided with adaptability and diversity.Ninety-seven soybean landraces from Hebei growing-are...
Keywords:Soybean  Germplasm resoures  Low-P tolerance  Germplasm screening
