Germination Traits

AbstractGenetic 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.

The Relationship

Exposure of tobacco (Nicotiana tabacum L.) seedlings to low ambient air temperatures during the 3 weeks prior to transplanting resulted in premature flowering. The percent premature flowering observed varied with the location of the experiment, the year, and the total degree units of temperature below 20 °C. A positive relationship between accumulated hourly temperatures below 20 °C and percent premature flowering was observed over four years at two locations.Key words: low temperature, premature flowering
