摘要：

A plant with drastically reduced vigour was observed in a population of diploid barley (Hordeum vulgare) raised from seeds exposed to gamma radiation. Cytological studies revealed that the plant was nullisomic with 2n = 12. At meiosis, regular formation of 6 bivalents was observed. The plant was totally sterile and produced neither stainable pollen nor seed.
