Integration of Conservation Strategies of Plant Genetic ... - Genres

5. The collection some of Brassica sp. contains different lines, cultivars of cauliflower, cabbage,
chinense cabbage, Brassica campestris as a source of resistance to diseases - 40 accessions.
6. The collection of Cucurbits - 110 accessions and includes Cucurbita maxima (winter squash),
Cucurbita pepo (summer squash), Cucumis melo (melon), Cucumis sativus (cucumber). The
materials contain mostly old polish, russian cultivars and landraces.
7. The collection of Lactuca sp. - 45 accessions and covers polish landraces, old cultivars of
different forms of lettuce and wild species.
All collected accessions are documented with regard to passport data, and 40% of those
accessions have been evaluated on morphological, economic and other characters according to
IBPGR recommendation, to needs of the breeders. lnformation related to the materials is stored
in computerized database.
Full evaluation is done for few species (garlic, onion, tomatoes, beans). Evaluation is carrying out
in special field trials during three growning seasons.
During evaluation attach oneself importance not on yielding, but to valorization of morphological
characters, occurance of determined genes and also on characters, which are especially valuable
in given materials (resistance to diseases, to stress conditions, source of sterility et.c.). Such
informations can be very helpful at the beginning of new breeding programme. Characterization,
multiplication, evaluation and some regeneration is carried out in close collaboration with
breeding organizations, agricultural universities and individual breeders.
Germplasm collecting and collaboration with different institutions
Source of new accessions are private producers, Polish and foreign scientific institutes and
collecting missions organized both in Poland and abroad. 3-4 short are organized every year time
exploration missions are organized year, which provides us with rare and valuable material, from
different regions of Poland.
The Territory of Poland is successive penetrated, on a base of earlier prepared exploration plans.
The route of expeditions lead through the old Polish centres of vegetables cultivation, where we
suspect to find interesting us germplasm.
Genetic resources are collected:
- in allotment gardens.
Such gardens exist in each town in Poland. The workers - amateur cultivate in these gardens very
old cultivars and landraces of many vegetables and other plants for longtime. So, these gardens
are often source of interesting us materials.
- in small farms in villages
The most valuable materials origin from small primitive farms. According to polish tradition
around the houses ought to be small home garden for own needs. In these gardens, mostly by old
farmers, are grown old local cultivars the same for years from force of habit, for pleasure.
Sometimes the tradition of their cultivation is going from generation to generation. The old
