Unraveling the Genetic Basis of Fruit Quality in Kiwifruit: Insights from Genomic Studies
Bibliographic record
Abstract
Different kiwifruit germplasms have obvious genetic differences in fruit quality. To better understand the genetic basis of kiwifruit fruit quality, this study collated the achievements in genomics, transcriptomics and metabolomics in recent years. We focused on introducing the main quality traits such as sweetness, acidity, texture and aroma, and analyzed their genetic regulation methods and related metabolic pathways. The establishment of high-quality reference genomes, the application of high-throughput sequencing, and the acquisition of rich genomic resources have all promoted the discovery of important genes, transcription factors, and quantitative trait loci (QTL) related to quality traits. Through case studies on sweetness, acidity, texture and aroma, we demonstrated how molecular-level research results can be transformed into specific breeding goals. This study also explored the prospects of genomic selection (GS) and marker-assisted selection (MAS) in kiwifruit breeding, as well as the advantages and difficulties of integrating genomic data in breeding. This study provides valuable references for researchers and breeders in cultivating new kiwifruit varieties with better flavor, higher nutrition and stronger market competitiveness.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
