Multi-environment analysis of grain yield in a diverse set of bread wheat genotypes

Abstract

A diverse set of 50 bread wheat genotypes was evaluated at 16 different locations belonging to four major wheat growing zones of India during 2016-17. The yield data was analyzed using Eberhart and Russel (1966), AMMI and GGE biplot stability models. Genotypes G14 and G26 were identified as the most stable genotypes based on Eberhart and Russel (1966) model, whereas genotypes G10, G14, G18, G23, G26, G30, and G47 were identified stable as per AMMI model whereas five genotypes G26, G23, G10, G43 and G14 were found stable as per GGE biplot analysis. Genotypes G14 and G26 were turned out to be the most stable genotypes based on these three stability models. The G48 ranked best for (Durgapura and Pantnagar); G29 (Powarkheda) and G35 (Hisar, Delhi and Ludhiana) based on grain yield performance. The GGE bi-plot indicated Durgapura to be an ideal environment followed by Hisar, Ludhiana, Delhi, Pantnagar, and Powarkheda that could be recommended for the future wheat breeding programmes aiming towards yield enhancement.

Genotype × environment interaction and stability analysis for seed yield and yield components in sesame (Sesamum indicum L.) in Benin Republic using AMMI, GGE biplot and MTSI

“…The two methods are complementary and were used simultaneously by several authors to analyze MET data [ 20 ]. The AMMI model includes both additive (ANOVA) and multiplicative (PCA) components and account for the underlying interaction patterns [ 21 , 22 ]. The GGE biplot, more recent than AMMI model, shows simultaneously mean performance and stability, optimized environments for specific accessions, and help to identify mega-environments [ 23 ].…”

Effect of terminal heat stress on physiological traits, grain zinc and iron content in wheat (Triticum aestivum L.)

“…Wheat (Triticum aestivum L.) is one of the most cultivated cereal crops with an acreage of 220 million ha and a total production of 734.0 million t worldwide (FAO 2018). India reached a landmark achievement in the year 2018-2019 with a total wheat production of 101.2 million t out of a cultivated area of 29.5 million ha (Singh et al 2020). However, despite the highly fertile Gangetic plain, productivity in the North Eastern Plain Zone of India is lower than the North Western Plain Zone.…”
