摘  要：
以栽培大豆和滩涂野大豆杂交组合(N23674×BB52)亲本及其经逐代耐盐性筛选获得的4个F4∶5家系为研究对象,对其苗期耐盐性、农艺性状、籽粒品质进行了分析和比较。结果表明:F44个株系的农艺性状都介于两亲本之间。盐胁迫下F5株系幼苗的耐盐系数、干物质积累和相对生长速率高于母本栽培大豆N23674,其中4076株系最为突出。籽粒品质较其父本BB52种群有明显改善,主要表现在籽粒中蛋白质和多数必需氨基酸、含硫氨基酸含量及氨基酸总量高于双亲,粗脂肪含量介于双亲之间,且接近于其母本N23674;4076和4111株系亚油酸含量超过双亲。

摘  要：
Glycine max cultivar N23674 (sensitive to salt),salt-born Glycine soja BB52 population (tolerant to salt) and four F4∶5 families were selected for salt tolerance study.Selection traits included seedling salt tolerance,agronomic traits (such as plant height,branch number,stem nodes,pod number,weight of 100 seeds) and seed quality (such as content of protein and fat content,composition of amino acids and fatty acids).The results showed that agronomic characteristics of 4 F4 hybrids ranged between parents.The salt tolerant coefficient,dry matter and relative growth rate of F5 hybrids under salt stress were obviously enhanced comparing to female parent N23674. Seed quality was obviously improved comparing to male parent BB52. Contents of protein,essential amino acids and sulfur-containing amino acids exceeded those of their parents,while the contents of fat were between their parents and close to those of N23674.Contents of C18∶2 in 4076 and 4111 strains were more than those in their parents.
