摘要/Abstract

摘要： 研究表明，（1）普通小麦品种间盛花期穗胆碱浓度存在着极显著差异；系谱分析表明这一生理性状具有遗传性。（2）盛花期穗胆碱浓度与赤霉病田间抗性之间呈极显著负相关，即与病圃病小穗率、反应级值均呈极显著正相关（r1=0.8634），可作为筛选小麦赤霉病抗源的重要生化指标这一。（3）富含胆碱的残留花药、雌蕊及早期颖果是禾

Abstract: The study shows the ranges of genetic variation of choline concentrations in flowering spikes among bread wheat varieties, the correlation of both the choline concentrations and the resistances to wheat scab [Gibberella zeae(Schw) Petch] and the action-patterns of a higher concentration of choline t

Key words: Wheat variety, Choline concentration, Wheat scab (Gibberella zeae), Resistance, Relationship
