Rumple said Zelena is the most powerful sorceress even before she put the pendant on. Rumple didn't know about pendant until Zelena slaved him after his resurrection. But he was afraid of her long bfore, for example he had to send Robin to Oz, because Dark One worried about the Wicked Witch. And about Regina, well, she's definitly the most powerful sorceress, after Dark Ones it has been said Zelena is the most powerful. Regina fighting with her mother was almost always losing., also she needed Emma's help to defeat Snow Queen's ice warrior. But I think Regina is one of the most powerful sorceress, althrough not the most powerful.

One more thing, Zelena got was weakened by Merlin's wand because of Regina's spell. She enchanted the wand to weaken the first person who use it (at least that's what I think).
