Reply To: Is there a way to tell if an Esrog is murcav?

AronChaim, if my pollen contamination theory is correct, the Chazon Ish strain would not be immune the ‘murkave bidei shamayim. I don’t know how the C.I. got its yichus and what the Gadols means of telling was. A Moroccan importer I knew three shmitas ago claimed a 600 year mesorah.

Sam2 for starters read Rav Kook’s Pri Ezt Hadar, and there is massive 19th century debate on the Corfu saga.
