Summary: This study aimed to identify stable rice genotypes tolerant to salt stress using AMMI stability model analysis. The results showed that CSR 36 was the most ideal genotype, while CHK2 and IR 87952-1-1-1-2-3-B were the most stable genotypes with above average yields. Genotypes GN13 and GN11 also showed potential for specific salt stress environments in India.

Summary: This study assessed the relationship between multiple locations and genotypes, analyzed the adaptability and stability of faba beans, and proposed the most ideal cultivation conditions and genotypes. The results showed that crude protein content, plant height, and thousand-seed weight were positively correlated with seed yield, while other qualitative variables were negatively correlated. Tanagra cultivar exhibited the highest seed yield under conventional management, and Ste1 and Ste2 showed promising genetic materials. Based on the results, Tanagra cultivar and Ste2 genotype are the most ideal choices.

Summary: Novel blackgram mutants were isolated through gamma irradiation, with desirable mutants selected for yield-related traits. Traits such as number of pods per plant, number of clusters per plant, and number of pods per cluster showed a strong direct association with single plant yield. Specific genotypes showed limited environmental interaction, as revealed by GGE biplot.

Summary: The novel multi-environment competition individual-tree mixed model showed better fit and higher individual narrow- and broad-sense heritabilities compared to the model without competition, especially for traits affected by competition. Accounting for competition increased direct additive variance, reduced residual variances, and did not significantly change the across-site additive genetic correlation.

Summary: The assessment of 1000-kernel weight is crucial for determining maize grain yield, and understanding its genetic mechanisms is important for improving overall performance. This study focused on 26 doubled-haploid maize lines and evaluated genotype by environment interaction, selection of stable lines, and estimation of additive and additive-additive gene interaction effects. Results indicated significant effects of genotype and environment, as well as genotype by environment interaction, on 1000-kernel weight. The lines KN07 and KN10 were recommended for further breeding due to their stability and highest average weight.

Summary: This study proposes a GGE model based on Bayesian inference that considers heteroscedasticity across environments and evaluates its implications in the interpretation of real and simulated data. The research shows that ignoring heteroscedasticity can change the inference on the stability and adaptability of genotypes, and different patterns of correlations between environments also affect the representativeness and discrimination of the target environment.

Summary: This study investigated the adaptation and stability of 11 Gardenia jasminoides genotypes at three experimental sites in Jiangxi Province. The results showed that genotype, environment, and genotype-environment interaction had significant effects on Gardenia jasminoides crocin contents. The HC20 genotype exhibited high and stable crocin contents, and Fengcheng and Gongqingcheng were identified as optimal test sites for genotype selection.

Summary: Genotype-by-environment interaction analysis is crucial for recommending the best crop genotypes and production environments. This study focused on determining the impact of GEI on seed yield in tepary bean and providing recommendations for cultivation in drought-prone environments. The results showed significant GEI, with genotype performance varying across environments. Several high-yielding tepary bean genotypes suited for drought-prone environments were identified based on BLUPs, YSI, and Pi.

Summary: This experiment compared the yield performance of hybrid maize and open-pollinated varieties in different seasons and found that the production potential of hybrids varies due to regional and seasonal differences. Correlation analysis revealed a positive correlation between grain yield and cob characteristics, and a negative correlation with reproductive traits. P3355 and Bisco gold 941 showed the highest yield in both seasons, suggesting their suitability for cultivation in the study area.

Summary: The interaction between genotypes and environments is crucial in plant breeding programs. A variety of models and mathematical methods have been developed to understand this genotype-by-environment interaction (GEI) in multi-environmental trials (METs), also known as stability analyses. However, the contribution of improved management in yield increase has hidden the true size of GEI, which can be revealed by comparing new and old varieties in a single experiment. Researchers need to dissect the usefulness of these methods to calculate stability indices and select superior genotypes.

Summary: This study aimed to explore the application of Bayesian inference in analyzing multi-environmental trials data using genotype main effects and genotype x environment interaction effects model, resulting in parsimonious models and better predictive ability. The study found that the Bayesian method provided more flexibility in attributing inference to model parameters related to the biplot representation, and the maximum entropy prior led to a more discriminating selection of parameters and better noise elimination compared to models assuming non-informative priors for multiplicative parameters.

Summary: Cowpea is a legume crop widely grown in the Sudan Savanna, with grain yields varying significantly among years and soil types. The study found that the interaction of year and soil type was the main cause of yield variation, with environmental factors and genotype-environment interactions playing a crucial role in determining yield stability. Soil fertility, water holding capacity, and nutrient content were identified as key factors influencing grain yield variation in different soil types.

Summary: Mixed cropping is seen as a resource-efficient method to meet high produce demands while maintaining biodiversity and reducing environmental impact. Current breeding programs lack focus on enhancing general mixing ability (GMA) and overlook biological interactions within species mixtures. A new model framework has been established to evaluate GMA and SMA, with incomplete factorial designs showing potential to improve genetic gain significantly by testing more genotypes with the same amount of resources. The Pr/As concept can further maximize GMA in an informed and efficient way, providing valuable insights into competitive and facilitative interactions in mixed plant communities.

Summary: Organic farming and breeding wheat varieties with enhanced mineral content can improve the nutritional quality of wheat bread. Diverse population varieties resulting from participatory plant-breeding processes show more differences in their profiles when grown in less fertile soils, highlighting the benefits of genetic diversity for diverse nutritional intake and sensory properties.

Summary: Plant domestication is a form of mutualism between humans and crops, which in turn affects beneficial interactions within and between crop species and their associated microbial partners. Manipulating genetic diversity in agrosystems can promote beneficial interactions through niche partitioning, facilitation, and kin selection. However, factors such as decreased molecular and functional diversity, mass selection, and increased use of chemical inputs have led to reduced benefits from niche partitioning and facilitation. In contrast, kin selection has likely been promoted since modern breeding. Further research is needed to explore the role of crop phenotypic plasticity and human-mediated selection on cooperation via kin recognition. Plant breeding and agricultural practices play a vital role in promoting beneficial interactions within and between species for the sustainability of agroecosystems.

Summary: This study examined the functional traits and ecological knowledge of farmers in managing semi-domesticated Phaseolus beans in the Colombian Andes. The findings suggest that these traits contribute to the resilience of agroecosystems and that a combination of emic and etic perspectives is necessary for a comprehensive understanding of the roles of functional traits of cultivated plants.

Summary: Supporting farmers in their transition to sustainable agricultural practices requires addressing the uniqueness of their individual situations. We propose a 5-step approach based on pragmatic inquiry and community of practice, which involves clarifying changes, mapping them, recording surprises, questioning collective action and organization, and reorienting individual projects to match collective actions in the agro-ecological transition.
