Pathogenesis and Varietal Screening for Panama Wilt Disease of Banana in Pakistan
Bibliographic record
Abstract
Banana is the world largest fruit crop with an annual production of 114 million tonnes and Pakistan produces 154,800 tons annually. Panama wilt caused by Fusarium oxysporum f. sp. cubense (Foc) is the most widespread and destructive banana diseases worldwide. In Pakistan Panama disease was first recorded in 2012 in few banana fields of district Thatta and Hyderabad in the Sindh. The infection processes and mechanisms of pathogenesis of Foc in relation to symptoms expression and evaluation of Cavendish varieties for panama wilt of banana were studied. Pathogenesis was confirmed by establishing Koch’s postulates. The experiment was to evaluate occurrences of necrotic and wilting symptoms and the disease intensity on banana suckers of Cavendish cultivar, two months plantlets were artificially inoculated with 106 conidia/ml suspension of Foc. Five tested Cavendish varieties viz., w11, G9, Basari, Pisang and BT10 showed low to high average of score of wilting and necrotic symptoms. Based on the calculation of disease intensities, all Cavendish varieties tested were identified as susceptible to Foc infection.

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.
