UCR reports W. Murcott arose from a seed from a Murcott tree and that Nadori assumed a chance hybrid with unknown pollen. Whether it resulted from self-pollination or pollen from another variety is unresolved. The prior Murcott × Unknown expression is replaced with unknown parentage; this record does not establish a cross.
