Partial resistance to white mould in dry bean

Abstract
Balasubramanian, P. M., Conner, R. L., McLaren, D. L., Chatterton, S. and Hou, A. 2014. Partial resistance to white mould in dry bean. Can. J. Plant Sci. 94: 683–691. White mould, caused by Sclerotinia sclerotiorum (Lib.) de Bary, is a constraint on dry bean (Phaseolus vulgaris L.) production across Canada. Under high disease pressure, dry bean cultivars succumb to the disease resulting in a severe loss of seed yield and quality. Disease development is highly influenced by environmental conditions. In the absence of complete resistance to white mould, dry bean cultivars with both field resistance (avoidance) and physiological resistance would be preferred by growers in order to reduce disease risk and production costs. The objective of this study was to characterize select dry bean genotypes for field resistance to white mould in inoculated disease nurseries, and physiological resistance in a controlled environment. White mould ratings ranged from moderately susceptible to susceptible. Dry bean cultivars lacked both field resistance and physiological resistance. Germplasm lines I9365-25, G122, A 195 and I9635-31 had low disease severity ratings (5.1 to 5.6 at 26 d after inoculation using a 1 to 9 visual disease rating scale) in controlled environment indicating physiological resistance. L 192, MO162, 92BG-7 and OAC Rico also had acceptable levels of physiological resistance (severity ratings of 5.8 to 6.2 at 26 d after inoculation). G122, A 195, L 192 and MO 162 had low white mould disease incidences (16 to 25%) in the field over 4 yr indicating field resistance to white mould. These genotypes may be used as parents in the development of dry bean cultivars with enhanced resistance to white mould.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
