History of PMHZ
The Plant Breeding Station was established in Strzekęcino in 1950. Potato breeding and seed material was collected from secured and propagated lines of varieties in the years 1945–1950 on farms in the Koszalin–Bobolice region. In 1949, a decision was made to conduct breeding activities in Strzekęcino.
Initially, conservation breeding and potato seed production were carried out, and a few years later the breeding of new varieties also began. The basis for potato breeding was a small greenhouse and a converted storage facility, where breeding lines and clones were stored.
In 1962, the Koszalin Potato Breeding Center was established, becoming the overarching unit for all potato breeding activities in the Koszalin, Piła, and Słupsk regions. The Plant Breeding Station in Strzekęcino served as the leading site for all KHZ stations.
The appointment of the Chief Breeder at KHZ, Professor Edward Kapsa, provided an impulse to expand breeding work on potatoes across the stations and to develop the entire infrastructure related to potato breeding. New greenhouses and laboratories were built, breeding specialists were employed, and potato breeding technology was improved.
In potato breeding, instead of a general direction, a specialized focus on starch potato breeding was established, characterized by high tuber yield, high starch content, and high starch yield per hectare.
In the field of breeding and seed production, extensive cooperation was carried out with universities, the Potato Institute in Bonin, Plant Breeding Stations, as well as field services responsible for seed production and farmers.
A large and highly skilled team of potato breeders was trained and developed in Strzekęcino, many of whom later worked in various plant breeding stations across the country. Among those who made significant contributions to the development of breeding in Strzekęcino and other stations were: engineer Bronisław Fiszer, the organizer of potato breeding at the station; as well as Jan Frieske, Henryk Świstowski, Wojciech Schulc, Wacław Głowa, Juliusz Kamasa, Władysław Kuszel, Leszek Styszko, Stanisław Pera, Zdzisław Dudek, and Zbigniew Hartyn-Leszczyński.
