摘　　要：本文报导了栽培甜菜与白花甜菜杂交及回交后代Ｂ＿４Ｆ＿５（ＶＶＣ２ｎ＝３ｘ＝２７）无融合生殖株系的共同形态、生化特征以及其变异情况。观察了叶片形态、颜色、株型、抽薹、过氧化物酶及酯酶同工酶的变异。结果显示，无融合生殖株系间及株系内都存在着明显的变异，株系间的变异大于株系内的变异，同时讨论了不同变异产生的可能原因。This paper reports the same morphological，biochemical Characters and their variationsof the apomictic lines from B4F5（VVC 2n＝ 3x＝ 27） of cross and backcross offspring betweenB. vulgaris and B. corollflora. The variations of leaf shape，colour，plant types，bolting，per-oxidase and esterase isozvme are observed.The results shown that obvious variations exist inthe intra- and inter-apomictic lines. The variations of interline is more than that of intralines.Also the possible causes of different variations are discussed.
