From six best growing exotic pine species P. echinata Mill. was studied in detail continuously for 9 years for its reproductive performance in relation to male and female cone-set, seed-set and seed qualities. The species has apparently adapted well to the Himalayan climate in Kumaon. Fluctuations in reproductive performance over the years is probably due to the climate.
