摘要
1066A×C445是利用矮秆高度雄性不育系育成的我国第一个夏谷杂交种,籽粒产量表现了较强的杂种优势,在省区试中较对照种平均增产16％以上。研究发现1066A×C445较对照品种在单茎叶面积、灌浆期光合作用强度,亩成穗率、穗粒重、经济系数等方面存在优势。这是杂交种形成籽粒产量优势的基础。
[1066A×C445]is the First Summer millet hybrid strain breeded by stem male sterile strain with dwarf. Its yieidis more than CK with a mean yeild incras of 16% in regional test of strains. This study show that [1066A×C445] has hybrid vigor in leaf area of single stem, photosynthesis during filling period, spike density, grain weight per spike and harvestindex.
