不同玉米品种主要农艺性状与产量的灰色关联度分析
Grey Correlation Analysis of the Main Agronomic Traits and Yields of Different Maize Varieties
【摘要】 为筛选出适宜百色地区种植的玉米品种,本研究采用灰色关联度分析法,对12个玉米品种的农艺性状进行了分析。结果表明,农艺性状与产量的关联度大小为:出籽率>百粒重>穗粗>行粒数>穗行数>穗位高>秃尖>穗长>株高>生育期>茎粗>绿叶率。出籽率、百粒重是影响玉米产量的主要因素,茎粗、绿叶率对玉米产量的影响较小。因此,在玉米育种工作中,应重视出籽率、百粒重的选择,同时要结合其他农艺性状进行综合考虑。
【Abstract】 In order to screen corn varieties suitable for planting in Baise areas, the agronomic characteristics of 12 corn varieties were analyzed by gray correlation analysis. The results showed that the correlation between agronomic traits and yield was as follows: seed output rate>100 grain weight>spike coarseness>number of rows>number of spikes>spike position>bald tip>spike length>plant height>growth period>stem thickness>green leaf rate. Seed yield and grain weight were the main factors affecting maize yield, and stem thickness and green leaf rate had little impact on corn yield. Therefore, in corn breeding, attention should be paid to the selection of seed rate and 100 grain weight, and comprehensive consideration should be combined with the correlation of other agronomic traits.
