阜阳地区部分主推玉米品种不同密度产量性状的比较

Comparison of Yield Characters of Maize Varieties under Different Densities in Fuyang Area

[目的]进一步了解适合阜阳地区生产的玉米品种特性。[方法]从市场上搜集了11个主推玉米品种进行不同密度对产量性状的比较试验。[结果]穗长、穗粗、穗行数、行粒数、单穗棒重、单穗粒重及出籽率不同品种间均存在较大差异;穗长、穗粗及行粒数不同密度间差异较大,说明这3个因素受环境影响较大,其他几个性状影响较小;品种与密度互作对各性状影响不显著。[结论]从产量及抗病性等综合考虑,登海605、裕丰303、全玉1233、沃玉3号、郑单958品种较好,适当的密度可以获得良好的产量。

[Objective]The aim of the study was to further understand the characteristics of maize varieties suitable for production in Fuyang area.[Method]Eleven main maize varieties were collected from the market and compared with each other in different densities.[Result]There were significant differences in ear length,ear diameter,ear rows,row grains,panicle weight,grain weight per panicle and ration of grain weight to ear weight among different varieties.The differences of ear length,ear diameter and row grains between different densities were large,the results indicated that these three traits were greatly affected by the environment,while the other traits were less affected.The effect of variety and density interaction on each traits was not significant.[Conclusion]From the comprehensive consideration of yield and disease resistance,Denghai 605,Yufeng 303,Quanyu 1233,Woyu 3 and Zhengdan 958 varieties were better,and good yield could be obtained with appropriate density.
