“…However, less, the variation due to the environment, including differences in rainfall and temperature, led to inconsistent performance of finger millet genotypes in the North Coastal Region of the state. In contrast to our results, a large proportion of total variation contributed by the environment was reported in finger millet in the studies by Adugna et al (2011), Molla et al (2013), Dagnachew et al (2014); Birhanu et al (2016), Lakew et al (2017), andSeyoum et al (2019) whereas the studies by Dehghani et al (2006), Tolessa et al (2013), andSingamsetti et al (2021) unraveled GEI among the genotypes of field pea, wheat, and maize, respectively. The procedure of AMMI included the partitioning of GEI by PCs, followed by the significance of the interaction was measured by Gollob's F-test.…”

Finger millet, an orphan crop, possesses immense potential in mitigating climate change and could offer threefold security in terms of food, fodder, and nutrition. It is mostly cultivated as a subsistence crop in the marginal areas of plains and hills. Considering the changes in climate inclusive of recurrent weather vagaries witnessed every year, it is crucial to select stable, high-yielding, area-specific, finger millet cultivars. Sixty finger millet varieties released across the country were evaluated over six consecutive rainy seasons from 2011 to 2016 at the Agricultural Research Station, Vizianagaram. The genotype × environment interaction (GEI) was found to be significant in the combined ANOVA. Furthermore, the Additive Main effects and Multiplicative Interaction (AMMI) analysis asserted that genotypes and the GEI effects accounted for approximately 89% of the total variation. Strong positive associations were observed in an estimated set of eleven stability parameters which were chosen to identify stable genotypes. Furthermore, Non-parametric and Parametric Simultaneous Selection indices (NP-SSI and P-SSI) were calculated utilizing AMMI-based stability parameter (ASTAB), modified AMMI stability value (MASV), and Modified AMMI Stability Index (MASI) to identify stable high yielders. Both methods had inherent difficulties in ranking genotypes for SSI. To overcome this, the initial culling [i.e., SSI with culling strategy (C-SSI)] of genotypes was introduced for stability. In the C-SSI method, the top ten genotypes were above-average yielders, while those with below-average yield were observed in NP-SSI and P-SSI methods. Similarly, the estimation of best linear unbiased prediction (BLUP)-based simultaneous selections, such as harmonic mean of genotypic values (HMGV), relative performance of genotypic values (RPGV), and harmonic mean of relative performance of genotypic values (HMRPGV), revealed that none of the top ten entries had below-average yield. The study has proven that C-SSI and BLUP-based methods were equally worthy in the selection of high-yielding genotypes with stable performance. However, the C-SSI approach could be the best method to ensure that genotypes with a considerable amount of stability are selected. The multi-year trial SSI revealed that entries Indaf-9, Sri Chaitanya, PR-202, and A-404; and VL324 and VL146 were ascertained to be the most stable high-yielding genotypes among medium-to-late and early maturity groups, respectively.

“…The significant GEN×ME×YEAR interaction suggests the complex interaction of the genotypes with contrasting environments on the trait phenotypic expression. Similar reports were also observed in previous studies ( Kamutando et al., 2013 ; Mebratu et al., 2019 ; Yue et al., 2020 ; Singamsetti et al., 2021 ). Along with the global changes in climatic variables over the past decades, there is a growing consensus that future food production will be threatened by environmental conditions ( Ceglar and Kajfež-Bogataj, 2012 ; Steward et al., 2018 ).…”

“…During breeding practice, breeders often measure many traits related to yield and are faced with the problem of selecting stable and superior genotypes based on multiple traits. The multi-trait stability index (MTSI) has been successfully used for selecting superior genotypes based on multiple traits ( Koundinya et al., 2021 ; Singamsetti et al., 2021 ; Farhad et al., 2022 ; Lima et al., 2022 ; Padmaja et al., 2022 ), and has a tremendous potential to combine morpho-physiological and yield traits aiming at selecting hybrids under optimal and stress conditions ( Balbaa et al., 2022 ).…”

Under global climate changes, understanding climate variables that are most associated with environmental kinships can contribute to improving the success of hybrid selection, mainly in environments with high climate variations. The main goal of this study is to integrate envirotyping techniques and multi-trait selection for mean performance and the stability of maize genotypes growing in the Huanghuaihai plain in China. A panel of 26 maize hybrids growing in 10 locations in two crop seasons was evaluated for 9 traits. Considering 20 years of climate information and 19 environmental covariables, we identified four mega-environments (ME) in the Huanghuaihai plain which grouped locations that share similar long-term weather patterns. All the studied traits were significantly affected by the genotype × mega-environment × year interaction, suggesting that evaluating maize stability using single-year, multi-environment trials may provide misleading recommendations. Counterintuitively, the highest yields were not observed in the locations with higher accumulated rainfall, leading to the hypothesis that lower vapor pressure deficit, minimum temperatures, and high relative humidity are climate variables that –under no water restriction– reduce plant transpiration and consequently the yield. Utilizing the multi-trait mean performance and stability index (MTMPS) prominent hybrids with satisfactory mean performance and stability across cultivation years were identified. G23 and G25 were selected within three out of the four mega-environments, being considered the most stable and widely adapted hybrids from the panel. The G5 showed satisfactory yield and stability across contrasting years in the drier, warmer, and with higher vapor pressure deficit mega-environment, which included locations in the Hubei province. Overall, this study opens the door to a more systematic and dynamic characterization of the environment to better understand the genotype-by-environment interaction in multi-environment trials.

“…Grain yield is the most important trait in maize; however, this character is polygenic and sensitive to the exposed environmental changes (Acquaah, 2007). Under waterlogging stress, the low to moderate heritability estimates have been noticed (Edmeades et al, 1999) and the genotype by environment interaction (GEI) becomes greater for maize grain yield (Singamsetti et al, 2021). The purpose of the adaptation test is to determine the genetic potential and adaptability of candidate varieties in the targeted environments.…”

Unpredictable rainfall in the tropics often increases the risk of waterlogging or even flooding in agricultural lands, hindering the efforts to fulfill maize demands. Breeding maize for waterlogging tolerance is necessary yet challenging since performing varietal testing on a set of hybrids might be biased toward the presence of genotype and environment interaction (GEI). This study aimed to elucidate the GEI effects on yield and related agronomic traits of tropical maize hybrids under normal irrigation and waterlogging conditions and to assess the adaptability of these hybrids in such conditions using several stability models. Ten hybrids including two commercial checks were evaluated across 14 environments under normal and waterlogging conditions in Indonesia from 2018 to 2020. Waterlogging imposed at the V6 stage for ten consecutive days significantly hampered the plant height and ear height, slightly delayed flowering dates, and reduced yield and yield components. The genotype, location, and genotype by location effects were significant on yield, but the genotype by waterlogging effect was not. Stress tolerance index is highly significantly correlated (p < 0.01) with yield in both normal (r = 0.90) and waterlogging (r = 0.96) conditions. The GGE biplot analysis on yield revealed five sectors, two mega-environments, and five vertex genotypes. This study indicated the possibility of breeding maize hybrids tolerant to waterlogging (G05), as well as high-yielding hybrids under both conditions (G07).
