Abstract:

Using AMMI model and GGE-biplot, the agronomic traits (biological dry weight, moisture content of whole plant, plant height, spike height, and green leaf number) of 20 new varieties from 12 test sites in the 2023 Henan Muyuan silage corn regional trial were investigated. The results indicated that the two analysis methods were largely consistent. Yayuqingzhu 8 and Xinke 917 exhibited higher moisture content of whole plant; Kaiqing 229 and Zhoudan 326 had higher plant height; Zhengdan 3582 and Nongqing 903 had lower spike height; and Zhoudan 326 and Zhengdan 612 had more green leaves. All these varieties demonstrated good stability. However, there were partial differences in the assessment results between the two methods. For instance, the AMMI model indicated that Zhoudan 326 exhibited a moderately above-average performance in terms of stability for plant height and number of green leaves, whereas the GGE-biplot showed it had strong stability. The effects of genotype, environment, and genotype × environment interaction on all agronomic traits were extremely significant (P < 0.01). The cumulative contribution rate of the three principal components to the genotype × environment interaction effect ranged from 65.49% to 74.50%, indicating that the AMMI model effectively explained the interaction between genotype and environment. Furthermore, Ganyuqing 78 and Zhoudan 326 exhibited higher starch and crude protein content, along with lower neutral detergent fiber and acid detergent fiber content, which indicated that their comprehensive quality was outstanding. Through comprehensive comparison, Zhoudan 326 and Zhengdan 612 performed well, and can be planted and popularized in Henan Province and its neighboring provinces.

Key words: Silage corn, AMMI model, GGE-biplot, Interaction effect, Agronomic traits
