摘　　要：对小麦(Triticum aestivum L.)30个F_1代组合的穗部性状进行超高亲优势分析,并对配组的60个亲本的穗部性状进行相关分析。结果表明,30个组合F_1代材料的穗粒重、穗粒数、穗长、总小穗数、有效小穗数均有不同程度的超高亲优势,且穗粒数、有效小穗数的超高亲优势达极显著水平。子代与亲代材料穗部性状间均具有高度的相关性,穗粒数与穗粒重、穗粒数与总小穗数、穗粒数与有效小穗数、穗粒重与穗长、穗粒重与总小穗数、穗粒重与有效小穗数、穗长与总小穗数、穗长与有效小穗数、总小穗数与有效小穗数间相关性都达到了极显著水平。The over high parent heterosis of spike traits of 30 hybrids in wheat(Triticum aestivum L.) was analyzed, and the relation among spike traits of 60 parents was also analyzed. The results showed that there was over high parent heterosis of grain weight per spike, grain number per spike, panicle length, total spikelets number and effective spikelet number in all 30 hybrids, and the over high parent heterosis of grain number per spike and effective spikelet number was significance at the 0.01 level. There were highly significant correlation among the spike traits in hybrids and parents. And there were highly significant correlations between kernel number per spike and grain weight per spike, kernel number per spike and total spikelets, kernel number per spike and effective spikelet number, grain weight per spike and spike length, grain weight per spike and total spikelets number, grain weight per spike and effective spikelet number, spike length and total spikelets number, spike length and effective spikelet number, total spikelets number and effective spikelet number.
