利用灰色关联度分析方法,对云南省2009-2011年度田麦区域试验参试新品系的产量与产量构成因素进行分析,以明确云南田麦产量与产量构成因素之间的关系。结果表明,云南田麦产量与产量构成因素关联度大小顺序依次为:基本苗>穗粒数>株高>生育期>千粒重>最高分蘖>有效穗。在育种过程中,应重点对穗粒数、株高、生育期的选择,但不应忽略千粒重、最高分蘖、有效穗的选择,栽培上适当增加播种量,适时灌水施肥,保证基本苗、增加结实率。
The gray correlation analysis method was used to analyze the yield and yield components of the new lines from Tianmai Regional Trial in Yunnan Province from 2009 to 2011 so as to clarify the relationship between the yield and yield components of field wheat in Yunnan Province. The results showed that the order of the correlation degree between the yield and yield components of field wheat was as follows: basic seedlings> number of spikes per plant> plant height> growth period> 1000-grain weight> highest tillering> effective panicle. In the process of breeding, we should focus on the choice of grain number per plant, plant height and growth period, but we should not neglect the choice of 1000-grain weight, the highest tillering and the effective panicle, increase the sowing amount appropriately in the cultivation, timely fertilize and ensure the basic seedling and increase Seed setting rate.
