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Lophopyrume longatumEe 染色体对小麦小穗数的影响。发现Lophopyrumelongatum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
The effects of Lophopyrume longatumEe chromosome on the spikelet number of wheat were studied using the Chinese Spring Ee Chromosome Adduct or Dwarf Substitution Lines with the Chinese Spring common wheat as the genetic background. The 4Ee chromosome of Lophopyrumelongatum was found to have a strong effect on the number of spikelets. The chromosome 5Ee and chromosome 1Ee had a weaker effect on the number of spikelets
