摘　　要：本文总结了我们在甜菜属一些物种的种间杂交工作，涉及物种有栽培甜菜（ＢｅｔａＶｕｌｇａｒｉｓ　Ｌ．）、沿海甜菜（Ｂ． ｍａｒｉｔｉｍａ Ｌ．）、叶用甜菜（Ｂ， ｃｉｃｌａ　Ｌ．）、白花甜菜（Ｂ． ｃｏｒｏｌｌｉｆｌｏｒａＺｏｓｓ．）、小碗状花甜菜（Ｂ． ｐａｔｅｌｌａｒｉｓ　Ｍｏｑ．）、平匐甜菜（Ｂ。 ｐｒｏｃｕｍｂｅｎｓ Ｃｈｒ． Ｓｍ）等。杂交取得了成功，获得了各种有价值的材料，如带有白花甜菜染色体的栽培甜菜单体附加系系列，具有栽培甜菜和白花甜菜不同染色体组的各种异源多倍体（ＶＶＣ， ＶＶＶＣ及ＶＶＣＣ）的无融合生殖材料，具有栽培甜菜、白花甜菜和平匐甜菜染色体组的三种间杂种（ＶＣＰ），这些都是世界上首创的。通过对杂种后代的选择，已选择出抗褐斑病、根腐病的高产后代，正在进行比较式验，它对甜菜糖业生产将起到促进作用。The interspeciefic hybridization in Genus Beta is summarized. The species involved in the crosses were Beta vulgaris L., B. cicla L., B. corolliflora Zoss., B. patellaris Moq., B. procumbens Chr. Sm., et al. The distant hybridizations were success- ful. The different valuable materials were obtained, including the series of the monosomic addition lines of B. vulgaris with the chromosome of B. corolliflora, the apomixia materials of the allo-polyploids (VVC, VVVC and VVCC) with the different genomes of B. vulgaris and B. corolliflora, and the tri-interspecific hydrid(VCP) with three genomes from B. vulgaris(V), B. corolliflora(C) and B. procumbens(P). These re- sults were initiated in the world. The filial generation with high root yield and resist- ance to leafspot and root rot was selected. The control experiment is beeing conducted. It will promote the production of sugar beet and sugar industry.
