kidfishing said:But, with that as it is, we grow about 600 registered daylilies that all experience the same conditions and just a few die each year. The loss of daylily cultivars that are related by hybridizer raises the question about genetics or origin or something that caused them to die together. Or is it just happenstance?
Does anyone have a similar experience or opinion or science to offer?
There is a first step in using science to look at plant losses. It requires numbers. The question would be, is there any evidence that daylily deaths are not random by hybridizer. For all the registered daylilies that you have grown, for the years that you want to investigate, you would need a count of the number of cultivars you grow by hybridizers and the number that have died for each hybridizer.
An example, say I grow 50 plants and they were registered by five different hybridizers
Depending on the actual numbers, there are relatively simple tests available to check whether the deaths were happenstance or not. Otherwise there are more complex involved methods available.
