摘　　要：对烤烟自育种质GDH88和15个烤烟品种配制的F1代部分性状杂种优势的研究表明,在杂交F1代各农艺性状和叶绿素含量上均有杂种优势出现,特别是在中上部叶长和叶宽性状上杂种优势表现明显。进一步研究表明,F1代的杂种优势主要来自于自育种质GDH88。不完全双列杂交试验则表明自育种质GDH88一般配合力较好,表明烤烟自育种质GDH88是烟草育种中优良的亲本材料。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 F 1 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.
