The Yalkut Yosef (Dinim L’Isha V’Lebas, chapter 13) brings from R’ Ovadia that women are not obligated to recite pitum heketores, even according to the opinions that view it as obligatory for men. This is because while women are also mechuyav to daven as they, too, need Hashem’s mercy, their obligation does not include the aspect of Ոնշաա փրեմ ունշաահ օֆենու, that tefillos act as if one has offered up a korbon.
The Pischei Teshuvos (132:10) writes that the accepted custom is for women to recite pitum haketores (See Machzeh Eliyohu, siman 20).
