Recently, a research paper entitled “Deciphering the role of genotype-by-environment interaction in summer maize hybrids based on multiple traits using envirotyping techniques and genotype by yield × trait approaches” was published by the maize breeding team of the Institute of Dryland Farming in Field Crops Research, a top journal in the field of agriculture and forestry science( Impact factor 5.6, five-year average impact factor 6.1, CAS Zone 1).

This paper focused on the influence of the interaction between genotype and environment on the performance of maize hybrids, combined environmental characteristics and multiple character evaluation methods, and provided a theoretical basis for the selection of excellent hybrids specific to different maize ecological zones. Based on the multi-environment trail (MET) data of 28 varieties in 29 locations in Huang-Huai-Hai region from 2019 to 2021, the environmental ttechnique (ET) and the genotype by yield × trait (GYT) biplot approach were used to reveal the comprehensive effects of environment, genotype and their interaction on maize traits. This study provided important theoretical support for the regional selection of maize hybrids, and laid a foundation for the research of maize yield improvement and germplasm improvement. The research results further promote the application of genotype-environment interaction research in maize breeding, and provide coping strategies for future agricultural challenges brought by climate change.

This research was supported by the National Key Research and Development Plan, the Innovation Project of Hebei Academy of Agriculture and Forestry Sciences, the National Maize Industry System and the Hebei Science and Technology Support Plan.

The team's research results have also been published in Acta Agronomica Sinica, BMC Plant Biology, Frontiers in Plant Science, Agronomy Journal, and Agriculture.
