在英格兰浦利茅茨附近的维姆伯莱海弯岸边采集到的沿海甜菜的一近亲植株中发现了单胚种子和雄性不育性(它似乎是应当由细胞质决定)。此外,在来自丹麦的科郎德伯格一福约德的沿海甜菜生态型中找到了花粉可育株,其性能和 O-型的性能或与细胞质雄性不育糖甜菜相联系的保持系的性能是一样的。在这个丹麦沿海甜菜生态型中,自交可育性的程度和糖甜菜比较起来还是低的。 Single embryo seeds and male sterility (which seems to be depended on by the cytoplasm) were found in a close-bodied plant of coastal beet collected on the bank of the Vime Belek sea near Plymouth, England. In addition, pollen-fertile plants were found in the coastal sugar beet ecotype of Coliford-Foyode from Denmark, and their performance and O-type performance or performance of the maintainer line associated with cytoplasmic male sterility sugar beet was the same. In this Danish coastal beet ecotype, the degree of selfed-in fertility is still low compared to sugar beet.
