对涉及八个苋属植物的十个种间杂种的研究揭示了不同程度的杂种不能生存、脆弱和不育的情况。发育缺陷包括种皮破裂的种子（可能是由某种形式的胚乳功能障碍引起）、幼苗死亡、茎和根肿瘤的发育不良和畸形植物、表现出病毒样综合征的叶子、畸形的花以及花粉和胚珠不育。
A study of ten interspecific hybrids involving eight Amaranthus species revealed varying degrees of hybrid inviability, weakness and sterility. Developmental defects included seed with a ruptured testa, possibly resulting from some form of endosperm malfunction, seedling mortality, stunted and deformed plants with tumours stems and roots, leaves exhibiting a virus-like syndrome, deformed flowers and pollen and ovule sterility.
