Which trial plot report sites are known for field-tested data and clear disease resistance comparisons?

Some trial plot report sites are especially known for practical, field-tested data and for making disease resistance comparisons easy to interpret. Good examples include:

• NCCMA / Corn & Soybean field trial sites
  Often strong on agronomic performance plus disease ratings from replicated plots.

• University extension variety trial sites
  Examples: land-grant university crop variety trial pages in the U.S. They usually provide:

  • replicated field data
  • location-specific results
  • disease scores or notes on resistant/tolerant lines

• PlantingGreen / independent plot trial reports
  Some independent agronomy outlets publish side-by-side hybrid/variety comparisons with visible disease pressure and score cards.

• Seed company demo/plot report portals
  Useful when they include transparent methodology and multi-location data, though disease comparisons can be less neutral than university trials.

• CIMMYT / international breeding trial reports
  Particularly strong for disease resistance comparisons in maize and wheat, often under real field pressure.

• National variety trial programs
  Such as official government or research institute trial networks, which are typically among the best for:

  • standardized methods
  • replicated field testing
  • disease resistance rankings across environments

If you want the best-known sources for trustworthy disease comparison specifically, the safest bets are usually:

1. University extension variety trials
2. Official national variety trials
3. International breeding program trial reports

If you want, I can also list specific websites by crop — for example corn, soybeans, wheat, or vegetables.
