玉米产量与主要农艺性状的灰色关联度分析
Grey Relation Analysis Between Agronomic Traits and Yield of Maize
摘要
Abstract
11 traits related with yield for hybrid maize combinations were analyzed by grey relational grade analysis,relationship between main growth traits and yield traits were studied in the local(Guilin area)climatic conditions,and then the maize varieties which suitable for the Guilin area were screened. Results showed that the correlation for maize yield and related traits was that grain weight per spike 0.890 0,spike length 0.741 0,spike coarse 0.758 5,bald tip length 0.704 5,ear rows 0.709 5,grains per row 0.661 3,100 seed weight 0.739 4,seed rate 0.720 9,plant height 0.743 7,ear height 0.726 3,growth period 0.761 4. Correlation order was the grain weight per spike>growth period>ear diameter>plant height>ear length>100 grain weight>ear height>seed rate>number of rows per ear>bald tip length>grain number per row. Therefore,in maize breeding,it should pay great attention to the grain weight per panicle,growth period,is conducive to the cultivation of high yielding varieties,and then select the single grain heavy,growth period of suitable varieties popularized in Guilin area.关键词
