豫北地区小麦中选株系的综合评价

Comprehensive Evaluation of Selected Wheat Lines in North Henan

为客观公正地评价豫北地区小麦田间中选株系,为优良品种的审定打下基础,进而提高育种效率,本文依据品种同异比较原理与方法,对2019-2020年安阳市农业科学院的29个小麦田间中选株系的室内考种结果进行了综合分析。结果表明,在29个田间中选株系中,株系4,9,14,13,10,3和30综合表现优良。这些株系不仅产量性状好,其他主要农艺性状也表现较好。其各性状与理想目标性状的综合同一度值分别为0.8810,0.8327,0.8308,0.8286,0.8264,0.8165和0.8102,联系势均为强同势,显著优于对照周麦18和其余株系,很有希望成为优良品种。

In order to objectively and impartially evaluate the wheat field selected lines in Northern Henan,lay the foundation for the approval of excellent varieties,and further improve the breeding efficiency,this paper,based on the principle and method of comparison of similarities and differences of varieties,conducted a comprehensive analysis of the indoor test results of 29 wheat field selected lines in Anyang Academy of Agricultural Sciences from 2019 to 2020.The results showed that the 4 th,9 th,14 th,13 th,10 th,3 rd and 30 th lines were excellent in comprehensive performance among the 29 selected lines in the field.These lines not only had good yield characters,but also had good performance in other main agronomic characters.Their comprehensive identity values of each character and ideal target character were 0.8810,0.8327,0.8308,0.8286,0.8264,0.8165,0.8102,respectively,and their association potentials were strong identity,significantly better than other lines,which was very promising to become excellent varieties.
