megdavis said:More fun data from Dennis -- this is a graph of the number of hybridizers over time by ploidy
Are the graphs of the number of hybridizers over time or are they of the number of hybridizers who registered at least one daylily in each year or ? How are years in which a hybridizer did not register any daylilies handled (gaps in their registrations)?
How were the hybridizers who registeed both tetraploids and diploids handled?
How were, the admittedly, probably quite few, hybridizers who hybridized one ploidy for a few years and then switched to the other ploidy handled?
