Summary: This study empirically investigated the potential and limitations of reciprocal recurrent genomic selection in wheat breeding, finding that it can significantly improve hybrid wheat breeding efficiency with a selection gain of 1.0 dt ha(-1) compared to the original 20 parental lines. However, the need to develop robust genome-wide predictive equations was also highlighted for successful implementation.

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: Studying conspecific populations living in different microenvironments is important for understanding natural selection. In this study, two sunflower ecotypes in different habitats were investigated to estimate fitness and allele frequency change at different life stages. It was found that habitat- and life stage-specific selection contribute to the maintenance of divergent adaptation between populations.

Summary: Genotype by environment interaction affects the effectiveness of dairy cattle breeding programs in developing countries. This study aimed to optimize breeding programs for dairy cattle in different environments within Kenya. Simulation results showed that breeding strategies involving progeny testing bulls within each production system and using both phenotypic and genomic information can maximize genetic responses. Additionally, a joint breeding program with bull testing in all three environments produced the highest response using phenotypes alone.

Summary: This study investigates genotype by environment interactions of growth traits in razor clams reared in outdoor ponds and semi-natural environments. The results show significant genetic differences among families in different aquaculture environments. The heritabilities for growth traits are low to moderate, indicating that these traits can be effectively selected in both environments. This study provides guidance for breeding programs of razor clams in different aquaculture environments.

Summary: Extensive field evaluations were conducted across several locations in the southeastern US to assess the agronomic performance and stability of carinata genotypes. Results showed that carinata can produce viable grain yields in the region, but freezing temperatures pose a challenge to winter production. The southeastern US should be divided into three mega environments for future breeding efforts.

Summary: This study investigated the QTL-by-QTL, QTL-by-environment, and QTL-by-QTL-by-environment interactions by targeting four loci controlling grain length in rice. Through the development of near-isogenic lines with different genetic combinations and the analysis using linear models and interaction principal component analysis, the variations of additive effects, QQ effects, and environmental effects were estimated. The results showed differential responses of QQ effects to different environments, as well as differences between QQ effects including the long-grain allele at LKF and those excluding this allele.

Summary: In cowpea breeding, multi-environment trials are conducted to select high yielding lines. We explored different covariance structures to select the best model, and found that modeling heterogenous compound symmetry for genetic effects improved the predicted genetic gain compared to the traditional model.

Summary: In this study, genotypic information and heritability estimates were used to identify genomic regions associated with growth traits in Red Angus cattle. Pleiotropic QTL regions were discovered, and positional candidate genes previously associated with feed efficiency and growth traits in beef cattle were also found to be associated with Red Angus growth traits. Additionally, significant genotype-by-environment (GxE) interactions were detected, implicating the role of vasodilation, metabolism, and the nervous system in genetic sensitivity to environmental stress.

Summary: By conducting a common garden experiment, the study investigates the plastic and evolved responses of Crassostrea virginica to environmental changes and Perkinsus marinus infection. Results show that C. virginica exhibits a highly plastic response to environment across genotypes, but the lack of genetic variation suggests limited capacity for evolved responses.

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: This study revisited 100 populations of slender wild oat that were screened genetically 40 years ago. The results showed that the mesic ecotype, which is associated with moist environments, had higher adaptability in both moist and dry habitats, while the xeric ecotype, associated with dry environments, had declined in range and frequency. The genetic sequencing of modern populations revealed genetic uniformity within each ecotype, and additional introduced genotypes have spread even further than the mesic ecotype into the former range of the xeric ecotype.
