摘要： 利用10个小麦品种,对单茎库、源及其比值与产量的关系进行了初步研究.结果表明,库性状、源性状与子粒产量的相关性均未达到显著水平,小麦单茎库源比值与产量均呈正相关趋势,穗粒数/旗叶面积、穗粒重/旗叶面积与产量的表型和遗传正相关均达到极显著水平,对各产量构成因素均无明显不利影响,可作为小麦高产育种的重要筛选指标.

Abstract: :The relationship between sinks, sources, sink-source ratio per stem and yield were studied using 10 different wheat varieties.The results showed that there were no significant correlations between sink characters, source characters and yield.There were positive correlations between sink/source ratio per stem and yield.The phenoty pic and genetic correlations between grain number per spike/flag leaf area, spike grain weight/flag leaf area, and yield were significant at 1% level, which showed no negative effects on yield components.This indicates that the yield components can be harmonized at high yield levels.These results can serve as criterias for high-yield wheat breeding.

Key words: Winter wheat, Sink-source ratio, Yield
