Since the establishment of the Pomeranian-Masovian Potato Breeding Company in 1994, its structure and the breeding of new potato varieties have undergone many changes. Until 1998, all operations were carried out in three branches in Strzekęcino, Płochocin and Biesiekierz. In 1998, the Gdańsk breeding station, with its creative breeding centre in Krokowa, was incorporated into the Company, followed by the Słupsk station in 1999. In addition, a new branch in Jezierzyce was established. In January 2000, the Celbowo branch was established, featuring a creative breeding department in Krokowa. From 1999 to 2002, new varieties were bred in three centres: Strzekęcino, Płochocin and Krokowa. In 2002, the newly appointed CEO, Franciszek Klim, decided to modernise the Strzękecino station and discontinue the operations at the Płochocin station, followed by Krokowa in 2004. All breeding materials were secured and transferred to Strzekęcino. The decision to continue breeding of new varieties in a single, adequately equipped centre turned out to be fully justified. This is evidenced by the results of the breeding work. Between 1950 and 2015, 39 varieties were bred at the Strzekęcino centre, 16 of which were registered in the last decade. Since 2010, following a merger with the Plant Breeding Station in Szyldak, the Company has been operating four branches, with one breeding programme being implemented in the two centresm – Strzekęcino and Szyldak. Bearing in mind the previous experience related to the reorganisation of potato breeding, the Company’s Management Board decided to gradually discontinue creative breeding operations in Szyldak. Ultimately, as of 2017, the entire breeding programme will be carried out again only in Strzekęcino. Conservation breeding operations, i.e., increased production of micro- and mini-tubers, will be extended in Szyldak.

Pomorsko Mazurska HodowlaZiemniaka is the creator and owner of the majority of starch varieties in Poland. Of the 29 varieties displayed in the Register in 2015, as many as 14 were starch varieties, and among them, the sought-after and highly rated medium-early varieties. Since the beginning of the breeding of the new potato varieties in Strzekęcino and Krokowa, the starch variety has been the leading one. Hence the rich selection of these varieties in the Company’s offer. Despite the growing competition from western breeding companies in the case of ware, fry and chip varieties, the starch potato market is dominated by Polish varieties, most of which belong to PMHZ. The most valued ones include Hinga, Harpun, Pasat, Inwestor and Jubilat. All these varieties are characterised by high starch content and yield, immunity to viral diseases and potato blight. In recent years, the following four new medium-early starch varieties have been registered: Boryna, Kaszub, Szyper and Mieszko. The breeding programme is also being developed with respect to good ware varieties. This has resulted in the registration of several new, attractive ware varieties in recent years, such as Tajfun, Ignacy and Owacja, which are highly valued by the customers. Tajfun has received special praise as a very tasty, prolific and drought-tolerant variety.
