摘要: 利用11个不同的小麦基因型,对茎质系数的基因型差异及其与产量性状的关系进行了初步研究。结果表明:茎质系数在小麦基因型间存在极显著差异,与单茎草重、穗粒数、千粒重、穗粒重呈极显著的正相关,与穗数、经济系数呈极显著的负相关,重穗型品种的茎质系数极显著地高于多穗型品种,但其经济系数、子粒产量/草产量(库源比)极显著地低于多穗型品种,选育中间型品种可以实现高产与抗倒的有机结合。

关键词: 小麦, 茎质系数, 基因型, 产量性状

Abstract: The 11 wheat cultivars under plot cultivated condition were used in this experiment.The results showed that there were highly significant differences between various cultivars.W:L was highly significantly positive related to grass weight per stem,grains per spike,thousand grain weight,spike weight per stem and was highly significant negative related to spikes,harvest index.W:L of macro spike cultivars was much higher than that of multi spike cultivars,but harvest index and grain yield:grass yield(sink:source)were much lower.The breeding of mid typed cultivars can harmonize relations between high yield and lodging resistance.

Key words: Wheat, Weight:length per stem, Genotype, Yield character
