I read about diploids and tetraploids, but what on Earth are triploids??

Hope this helps - from the AHS Daylily Dictionary:
"Daylily chromosomes come in sets of eleven. Cells of diploid daylilies contain 22 chromosomes (two sets). Triploids contain 33 (three sets), and tetraploids contain 44 (four sets). Because the chromosomes in a nucleus must divide in half to form ova and pollen, triploids, with an odd number of chromosomes, are usually sterile. Tetraploids have not been found in species daylilies."
