Summary
Two flue-cured varieties of N. tabacum were crossed to putative progenitor species and to distantly related species. Heterosis for yield, plant height, and number of leaves was largest for crosses to progenitor species, particularly to N. otophora and N. tomentosiformis. The magnitude of this heterosis appeared to be greater than estimates presented in the literature for crosses among varieties of N. tabacum. An additional study presented some evidence for the genomic basis of heterosis in crosses of N. tabacum with N. tomentosiformis and N. sylvestris.
Zusammenfassung
Zwei für Röhrentrocknung geeignete Sorten von N. tabacum wurden mit vermutlichen Ausgangs- und mit entfernt verwandten Arten gekreuzt. Die Heterosis für Ertrag, Pflanzenhöhe und Blattanzahl war am stärksten bei Kreuzungen mit den Ausgangsarten, besonders mit N. otophora und N. tomentosiformis. Das Ausmaß dieser Heterosis schien die in der Literatur berichteten Schätzungen für Kreuzungen zwischen Sorten von N. tabacum zu übertreffen. Eine weitere Untersuchung erbrachte Hinweise für die genomatische Grundlage der Heterosis bei Kreuzungen von N. tabacum mit N. tomentosiformis und N. sylvestris.
