t1“Tropical Pumpkin (Cucurbita moschata Duchesne)”
e1“Compared with controls, yield per plant was unaffected by inoculation with potyvirus in resistant cultivar ‘Menina’”
e2“‘Waltham’, Mos166, ‘Taína Dorada’, and ‘Soler’ tested positive for PRSV when inoculated with PRSV and positive for ZYMV when inoculated with ZYMV”

Other claims from this paper (13)
- Observation Four susceptible or moderately resistant genotypes tested positive for the inoculated viruses.
- Observation Menina and Nigerian Local had zero symptom severity, less than other genotypes.
- Observation Soler had less ZYMV symptom severity than susceptible genotypes.
- Observation Soler PRSV severity resembled susceptible genotypes.
- Observation ZYMV generally caused greater symptom severity than PRSV.
- Intervention effect Potyvirus inoculation did not affect Menina yield relative to controls.
- Intervention effect Nigerian Local yield declined 45% relative to controls.
- Intervention effect Inoculated Waltham plots lost all yield.
- Observation Mos166 and Soler yield reductions ranged from 35% to 80%.
- Intervention effect Inoculation showed little evidence of differences in anthesis, fruit size and quality.
- Intervention effect ZYMV reduced Soler average fruit weight by 32%.
- Intervention effect ZYMV reduced Soler fruit diameter, mesocarp thickness and chroma relative to controls.
- Recommendation Authors favored Menina over Nigerian Local as a resistance source.
