Abstract

We studied F₁ heterosis of some traits of 15 flue-cured tobacco varieties and self-bred germplasm GDH88. The results showed that both F1 agronomic characters and chlorophyll content appeared heterosis, particularly in the leaf length and width. Further studies showed that F₁ heterosis mainly came from GDH88. Incomplete diallel cross trial indicated that GDH88 had good general combining ability, which demonstrated that GDH88 was excellent parent material for tobacco breeding.
