摘要

本世纪以来，北欧植物育种家选择了优良的基因型并发布了新的春小麦品种。然而，在这种改良种质中存在的表型多样性程度尚未得到准确的调查。本研究对近10年来在丹麦、芬兰、挪威和瑞典投放给农民的75个精选品种进行了表型评估。品种的分类与地理来源和品种发布年限无关。各自的簇内方差总是大于簇间方差。北欧春小麦种质资源的平均表型多样性为0.22，这并不奇怪，因为一些新品种是由老品种衍生的。地理来源对抽穗日数、秸秆日数、粒重、生物量日数和粒数有显著影响。同样，除株高外，国家×十年释放互作对其他性状均有显著影响。这些发现表明，尽管……

Diversity in Nordic spring wheat cultivars (1901–93)

Nordic plant breeders have selected superior genotypes and released new spring wheat cultivars throughout this century. However, the extent of phenotypic diversity that exists in this improved germplasm has not been accurately investigated. This study phenotypically assessed 75 selected cultivars released to farmers in Denmark, Finland, Norway and Sweden within the last 10 decades. Grouping of cultivars was not related to their geographical origin or decade of release. The respective within‐cluster variances were always larger than the among‐cluster variances. The average phenotypic diversity for Nordic spring wheat germplasm was 0.22, which was not surprising because some newer cultivars were derived from older cultivars. There was a significant influence of geographical origin on days to heading, straw, grain and biomass weight, and kernel number. Likewise, the country × decade of release interaction was significant for all characteristics except plant height. These findings suggest that irrespective of...
