本文报道了栽培甜菜（B．vulgarisVV）与白花甜菜（B．corollifloraCCCC）种间杂交，获得了2n＝36（VVCC）和2n＝27（VCC）杂种。观察了杂种F1的减数分裂行为。2n＝36杂种F1，终变期形成18个二价体的频率为98．73％，二价体环状结合方式为6个（范围4～10），棒状结合方式平均为11．99个（8－17）。用栽培甜菜回交，获得B1F2。经细胞学检查，染色体数均为2m＝27，其9Ⅱ＋9Ⅰ染色体构型频率为90．4％，减数分裂终变期的三价体频率占3．03％。后代出现大量形态变异及染色体数不同的植株。其与2n＝18的植株频率为41．58％，2n＝27的植株频率为30．19％，可能是无融合生殖形成的。2n＋1＝19的植株频率为10．39％，是附加白花甜菜染色体的异附加三体。
In this paper, interspecific crosses of B. vulgarisVV and B. corollifloraCCCC were reported, and 2n = 36 (VVCC) and 2n = 27 (VCC) hybrids were obtained. The meiotic behavior of hybrid F1 was observed. 2n = 36 hybrid F1, the frequency of 18 bivalents formed in the final stage was 98.73%, the number of bivalents was 6 (range 4 ~ 10), and the number of rod-like combinations was 11.99 8-17). Backcrossing with cultivated sugar beet to obtain B1F2. Cytological examination, the chromosome number were 2m = 27, the 9 Ⅱ +9 Ⅰ chromosome configuration frequency was 90.4%, the final stage of meiosis triad frequency accounted for 3.03%. Offspring there are a large number of morphological variation and chromosome number of plants. The frequency of plants with 2n = 18 was 41.58% and the frequency of plants with 2n = 27 was 30.19%, which may be caused by apomixis. The plant frequency of 2n + 1 = 19 was 10.39%, which was the additional additional trisomy of chromosome of Beet armywort.
