| 1 | A Study on Genotype-by-Environment Interaction Analysis for Agronomic Traits of Maize Genotypes Across Huang-Huai-Hai Region in China显示文摘Facing the trend of increasing population,how to increase maize grain yield is a very important issue to ensure food security.In this study,28 nationally approved maize hybrids were evaluated across 24 different climatic conditions for two consecutive years(2018-2019).The purpose of this study was to select high-yield with stable genotypes and identify important agronomic traits for maize breeding program improvement.The results of this study showed that the genotypeenvironment interaction effects of the 12 evaluated agronomic traits was highly significant(P<0.001).We introduced a novel multi-trait genotype-ideotype distance index(MGIDI)to select genotypes based on multiple agronomic traits.The selection process exhibited by this method is unique and easy to understand,so the MGIDI index will have more and more important applications in future multi-environment trials(METs)research.The genotypes selected by the MGIDI index were G22,G10,G12 and G1 as the high yielding and stable genotypes.The parents of these selected genotypes have the ability to play a greater role as the basic germplasm in the breeding process.A new form of genotype(G)main effects and genotype(G)-by-environment(E)interaction(GGE)technician,genotypeyieldtrait(GYT)biplot,based on multiple traits for genotypes selection was also applied in this study.The GYT biplot ranked genotypes by combining grain yield with other evaluated agronomic traits,and displayed the distribution of their traits,namely strengths and weaknesses. | Haiwang Yue Jianwei Wei Junliang Xie Shuping Chen Haicheng Peng Hongmei Cao Junzhou Bu Xuwen Jiang | 2022 | Phyton-International Journal of Experimental Botany2022，91，1： | 1 |
| 2 | Efficacy and Phytotoxicity Trial of Different Dosages of 4% Nicosulfuron SC on Weeds in Corn Fields显示文摘[Objective]The paper was to study efficacy and phytotoxicity of different dosages of 4% nicosulfuron on weeds in corn fields.[Method]With summer corn variety Zhengdan 958commonly used in field production in Hengshui area of Hebei Province of China as the test material,different dosages(1 050,1 500 and 1 950mL/hm2)of corn postemergence herbicide 4% nicosulfuron SC were sprayed during five-leaf stage of corn,and the treatments with water spraying and manual weeding were set as controls.The effects of different dosages of 4% nicosulfuron SC on weed control efficacy and safety and yield of corn were analyzed in order to determine the optimal dosage.[Result]Spraying 4% nicosulfuron SC with dosage of 1 500mL/hm2 during five-leaf stage of corn not only had better control effect against various weeds,but also did not produce phytotoxicity on corn,and the yield of corn was higher.[Conclusion]The study provided scientific information for using 4% nicosulfuron to eradicate weeds in corn fields. | Bu Junzhou Yue Haiwang Chen Shuping Peng Haicheng Xie Junliang | 2013 | Plant Diseases and Pests2013，4，6： | 0 |
