长龄番茄是含有隐性纯合耐贮基因(nor/nor)的一代杂种。其母本(双黄5号)是矮黄品种与含纯合nor基因的材料杂交,经后代分离选择而成,它既具有Tm2-nv抗病基因,又含有耐贮nor基因;其父本( 139F2-9-2-1-0-1)由园艺性状优良、但不耐贮品种84—142与合nor基因的材料Long-keeper杂交,
Long-aged tomato is a generation of hybrids that contain recessive homozygous storable genes (nor / nor). The female parent (Shuanghuang No.5) is a hybrid of short-bred yellow variety and homozygous nor-like gene, which is selected and isolated from offspring. It has both Tm2-nv resistance gene and nor-resistance gene; (139F2-9-2-1-0-1) was crossed with Long-keeper, a material that is a nor-gene, which is excellent in horticultural traits, but not storages 84-142,
