大豆[Glycine max（L.）梅尔。]是一种数量性状，影响发芽率，生活力和质量的储存种子。我们利用72个限制性片段长度多态性（RFLP）来鉴定一个分离群体中含有影响硬粒性的数量性状位点（QTL）的基因组区域。大豆（Glycine soja（Sieb. Zucc）。十字架五个独立的RFLP标记被发现与硬种子性状的变化。这些标记和它们之间的上位性相互作用解释了71%的硬实性变异。与i基因座相关的基因组区域占该分离群体变异的32%。这项研究说明了植物生理遗传学研究的一种方法。
Hard seededness in soybean [Glycine max (L.) Merr.] is a quantitative trait that affects the germination rate, viability, and quality of stored seeds. We have used 72 restriction fragment length polymorphisms (RFLPs) to identify genomic regions containing quantitative trait loci (QTL) affecting hard seededness in a segregating population from a G. max by a Glycine soja (Sieb. and Zucc.) cross. Five independent RFLP markers were found to be associated with variation in the hard-seeded trait. These markers and the epistatic interactions between them explain 71% of the variation for hard seededness. A genomic region associated with the i locus accounted for 32% of the variation in this segregating population. This study illustrates one approach to physiological genetic studies in plants.
