PSB Pn (UPL Pn 12) is a Valencia peanut variety derived from the 3-way cross between (UPL Pn 2 x FESR 1) x NC6. Its seed yield is higher than both check varieties. It exceeded the seed yield of BPI Pn 2 by 17.54 percent and PSB Pn-1 by 12.88 percent in the 12 NCT trials during the two dry cropping seasons across seven locations. It has better resistance to peanut rust and late Cercospora leafspot disease than both check varieties. Similar to PSB Pn 1, it has resistance to leafhopper damage. It has moderate resistance to Aspergillus flavus invasion during seed resistance test and it has high seed viability even after six months pod storage at ambient storage condition. It is a Valencia type of peanut with two to four seeds per pod. Majority of the pods are 3-seeded. It has tan seed coat. Similar to UPL Pn 4, it has sweet taste and could be used as boiled peanut and for peanut butter manufacture
