Re: Great new in depth paper on self-incompatibility in roses

"Ways of Achieving SC and Its Role in Hybrid Breeding Maintaining “pure” (highly homozygous) lines is also essential for hybrid breeding. Since SI species inherently favor outcrossing, achieving homozygosity may be hindered by the intra-specific crossing barrier itself and inbreeding depression. Mai...

Re: encyclopedia-of-plant-viruses-and-viroids 2019

I suggest a search using "rosa spp."

For PNRSV and roses (page 2095):

"The virus is transmitted by thrips vectors, the virus present in/on pollen, entering the host through injuries caused by thrips while feeding."
