Genetic mapping of seed germination traits has been performed with many plant species. In tobacco, however, investigations are rare. In the present study, a bi-parental mapping population consisting of 118 doubled haploid lines and derived from a cross between ‘Beinhart-1000’ and ‘Hicks’ was investigated. Four germination-related traits, total germination (TG), normal germination (NG), time to reach 50% of total germination (T50), and the area under the curve after 200 h of germination (AUC) were considered by examining seeds either untreated or after a moderate controlled deterioration (CD). Quantitative trait loci were found for all traits distributed on 11 out of the 24 linkage groups. It was demonstrated that, as in many other species, germination-related traits are very complex and under polygenic control.

已经对许多植物物种进行了种子萌发性状的遗传作图。然而，在烟草方面，调查很少见。在本研究中，研究了由 118 个双倍单倍体系组成的双亲作图群体，这些群体来自“Beinhart-1000”和“Hicks”之间的杂交。通过检查种子考虑了四个发芽相关性状，总发芽（TG）、正常发芽（NG）、达到总发芽50％的时间（T50）和发芽200小时后的曲线下面积（AUC）。未经处理或在中度受控恶化 (CD) 后。发现了分布在 24 个连锁群中的 11 个上的所有性状的数量性状基因座。研究表明，与许多其他物种一样，发芽相关性状非常复杂，并且受多基因控制。
