Martinez Farms - Certified Potato Seed

Para ver este pagina en Español marca aqui

We raise certified seed potatoes in the San Luis Valley at an elevation of 7,683 (2342 m.) Above sea level, in the southern part of the state of Colorado in the United States. We have the highest limited generation certified seed potatoes grown in the highest valley of the country. This gives our seed a "high country plant vigor" for seed grown where the climate is cold winters, hot-dry summers, low precipitation and much sunshine.

Martinez Farms began at its present location in Alamosa county in 1969 by father and son Phil and Freddy Martinez. They started raising certified potato seed in 1978. Segundo and Margie Diaz took over the operation in 1986. Since then the operation has been increased with the addition of the tissue culture laboratory and greenhouse propagation facility. This addition enables us to produce our own nuclear Stocks (basic seed) to increase our generation seed program. To see more of our operation click here.
