摘要: 基于2001—2016年湖北省小麦(Triticum aestivum L.)区域试验数据,分析了审定品种与对照郑麦9023的增产幅度、产量及主要农艺性状表现和变化趋势,以及审定品种性状间的相关关系。结果表明,与郑麦9023相比,27个审定品种增产率分布在-2.02%~9.16%,审定品种的产量、穗粒数、株高和全生育期平均数值较高,而有效穗数和千粒重平均数值较低;与郑麦9023相比,湖北省小麦审定品种产量潜力提高的同时,有效穗数和全生育期递增,而穗粒数、千粒重和株高递减;审定品种的有效穗数(0.65**)和千粒重(0.64**)与产量呈极显著正相关,有效穗数与穗粒数(-0.54**)相互制约。因此,增加有效穗数和千粒重,注意解决有效穗数和穗粒数的矛盾是当前湖北省小麦产量育种的主攻方向。

Abstract: Based on wheat (Triticum aestivum L.) regional trial in Hubei from 2001 to 2016, the yield-increasing rate, performance and changing trend of yield and main agronomic traits, and correlation among traits of wheat varieties released had been analyzed in the text. The results showed that, the yield-increasing rates of 27 wheat varieties released were from -2.02% to 9.16%, and the average value of traits such as yield, kernals per spike, plant height and days to maturity were higher, and the average value of effective spikes and 1000-grain weight were lower than that of Zhengmai9023. Comparing with Zhengmai9023, yield, effective spikes and days to maturity were increasing progressively,and kernals per spike,1000-grain weight and plant height were descending. Effective spikes (0.65) and 1000-kernel weight (0.64) were positively related with yield at 0.01 level. Effective spikes was negatively related with kernals per spike(-0.54) at 0.01 level. Keeping on raising effective spikes, intensifying selecting large-grain, solving the contraction of effective spikes and kernals per spike would be major directions of wheat breeding on yield at present in Hubei province.
