小黑麦是人工合成的新作物,自然界中不存在其任何品种资源,人工制造原始品系的工作在小黑麦育种中具有极其重要的作用。 黑麦属中共五个种,迄今人们主要利用普通黑麦(Secale cereale)中的栽培黑麦来合成八倍体小黑麦。实践证明,由栽培黑麦合成的这些原始品系一般部具有结实差和种子不饱满的严重缺点。 为了了解其他黑麦种合成的小黑麦的结实率和种子饱满度,笔者1984-1986年间种植了前几年进行小麦与黑麦可杂交性研究中合成的45个八倍体小黑麦品系,于开花前套袋,收获时测定套 Triticale is a new crop that is artificially synthesized. There is no variety of resources in nature. The work of artificially making original strains plays an extremely important role in triticale breeding. Five species of rye are from the Chinese Communists. To date, octoploid triticale has been mainly made from cultivated rye in Secale cereale. It has been proved that these original strains synthesized from cultivated rye generally have severe shortcomings of poor seed set and seed fullness. In order to know the seed setting rate and seed fullness of triticale grown in other rye cultivars, the author cultivated 45 octagonal triticale cultivars synthesized in previous years for the study of the hybridization between wheat and rye from 1984 to 1986 , Bagging before flowering, measuring set at harvest
