中文摘要：

耐储藏大豆种质的筛选是大豆种子耐储藏性遗传改良的基础。通过测定种子发芽率和电导率等指标，对87份大豆种子的耐储藏性进行评价。结果共筛选出耐储藏大豆种质38份，包括24份地方种质和14份栽培种质。相关分析表明，大豆种子的耐储藏性与种皮色素沉积量正相关，与大豆籽粒大小负相关。但在这些耐储藏种质中，20份种质的种皮为黄色，3份种质的百粒重超过22g；大豆种子的耐储藏性与电导率负相关，但并不显著，电导率只能作为评价大豆耐储藏性的参考指标。所筛选出的38份种质可直接用于大豆种子耐储藏性的遗传改良，为进一步研究大豆种子耐储藏性的遗传机理奠定材料基础。

英文摘要：

Germplasm with good seed longevity underlie the genetic improvement for seed longevity in soybean. Thirty-eight out of 87 germplasm with good longevity were screened according to the germination rate,total dissolved solids（TSD） and other in- dexes, including 24 landraces and 14 ctdtivars. The results showed that the seed longevity was positive related with the pigment content and negative related with the seed size. While among the germplasm with good longevity,20 ones bore yellow seed coats and three ones possessed big seed with 100-seed weight over 22 g. The relationship between seed longevity and TSD was nega- tive but not significantly,therefore,TSD could be used as reference index to evaluate soybean seed longevity. These elite germ- plasm with good seed longevity could be directly used in breeding progress and they provide genetic materials for seed longevity researches.
