Abstract Crop plants often face rapid environmental changes, and their ability to adapt novel conditions depends on whether specific traits can adjust match these changes. This capacity for adjustment, known as phenotypic plasticity, is frequently regarded a mere “response” rather than distinct trait with its own genetic basis, particularly in agricultural science. As result, plasticity oversimplified viewed an undesirable phenomenon when the goal achieve stability. In this study, we present quantitative metric measure provide evidence, through genome-wide association studies (GWAS) chickpea, that indeed genetically based trait, comparable any other agronomic trait. foundational study paves way future GWAS efforts harness offering new insights crop improvement strategies.

The genotype evaluation process requires analysis of GxE interactions to ascertain the responsiveness a various environments, including development early maturing rice. However, concept interaction is relatively specific grain yield. In contrast, yield highly polygenic, so assessment should be carried out with multivariate approaches. Therefore, in evaluating developed, especially for rice genotypes. study aimed develop comprehensive approach improve comprehensiveness and analysis. was conducted Bone Soppeng districts, South Sulawesi, Indonesia, two seasons. used randomized complete block design, where replications were nested across seasons locations. Two check varieties five replicated three times each environment. Based on this study, new based multiple regression index analysis, BLUP factor path considered adequate, This combined days harvest, biological yield, linear weighting combination all analyses. effectiveness reflected by high coefficient determination (R

Abstract Evolutionary studies indicate that species in stable environments often evolve with reduced plasticity, whereas those variable tend to maintain higher plasticity adapt changing conditions. Our study explores whether this evolutionary principle extends cultivated crops. In crop science, phenotypic is generally understood as a short-term response environmental factors. Yet, the long-term changes both plastic and non-plastic traits under different cultivation regimes remain largely unexamined. Herein, we developed novel mechanistic growth model, collectively termed Trait-Environment Fitness Interaction (TEFI) Model, if how trait varies among crops regimes. results, based on TEFI show trade-offs between fitness plasticity. Specifically, observed evolution of subjected intermittent cultivation, which experienced more environments. However, does not compensate for losses due high rate unpredictability. Conversely, relatively conditions Using real-world datasets, validated theoretical predictions suggest longer interruption, results highlight impact patterns its importance fitness. Ultimately, our findings illustrate principles captured by can inform sustainable improvement strategies.
