摘要
为筛选适宜鲁南地区种植的玉米品种及探索一种新的玉米品种综合评价方法,利用基于熵值赋权的DTOPSIS法对在鲁南地区常见的23玉米个品种的穗长、穗粗、秃尖长、穗行数、行粒数、百粒重等穗部产量性状及出籽率和产量进行分析。结果表明,‘浚单20’(Ci=0.99745)‘、良玉99’(Ci=0.47061)‘、郑单958’(Ci=0.47059)、‘金博士509’(Ci=0.47059)。‘先玉047’(Ci=0.29413)综合性状表现优秀,推荐作为鲁南地区优先种植的玉米品种。
In order to screen maize varieties suitable for planting in southern Shandong Province and explore a new comprehensive evaluation method of maize varieties, DTOPSIS method based on entropy weighting was used to analyze the biological characters of 23 maize varieties, such as ear length, ear diameter, bald tip length,ear row number, grain number per row, 100 grain weight, etc., as well as seed production rate and yield. The results showed that‘Jundan20’(Ci=0.99745),‘Liangyu99’(Ci =0.47061),‘Zhengdan958’(Ci=0.47059),and‘Jinboshi509’(Ci=0.47059).‘Xianyu 047’(Ci=0.29413) has excellent comprehensive characters and is recommended to be the preferred maize variety in southern Shandong.
