摘要: 以普通小麦中国春为遗传背景的中国春Ee染色体二体附加系或二体代换系为材料,研究了Lophopyrum elongatum Ee染色体对小麦小穗数的影响。发现Lophopyrum elongatum的4Ee染色体对增加小穗数有很强的效应,5Ee染色体、1Ee染色体对增加小穗数有较弱的效应。

Abstract: The spikelet numbers of common wheat lines with added or substituted chromosomes of Lophopyrum elongatum were screened. It is found that chromosome 4Ee of Lophopyrum elongatum has a strong positive effect on the spikelet numbers of common wheat, and chromosomes 1Ee and 5Ee has a faint positive effect.
