Non availability of modern high yielding varieties is the major cause of low rice yields in Hazara Division. Rice is the second important crop after maize in the kharif season, being cultivated on about 6500 hectares. This region is characterized with short growing season due to early onset of winter. Rice is grown as an irrigated crop in the valleys of the region. Presently about 20 indigenous land race varieties are grown under different names, JP-5 is the only recommended variety which is tall, susceptible to lodging and hence low yielder. Farmers have no other choice except to grow JP-5. Efforts were initiated at NARC to develop a suitable rice variety for the mountainous areas in Hazara Division of NWFP. Rice germplasm was obtained from IRRI, Philippines under International Network of Genetic Evaluation of Rice (INGER) It was evaluated for different agronomic traits and ultimately the line IR28128-45-2 was selected. The selected line performed better than the local cultivar JP-5 over the years and in different trials. The new line was named "Pakhal". It is 28% higher in yield, 15 days earlier, more responsive to fertilizers and tolerant to lodging. Pakhal, with longer grain and 24.7% amylose content has better grain quality than JP-5. The variety was released to farmers by NWFP Seed Council in November, 1993.
