| Description
| - Cílem práce bylo kvantifikovat míru nežádoucího opylení mezi regeneračními parcelami s genetickými zdroji téhož cizosprašného druhu Festuca pratensis, od níž byly k dispozici čtyři odlišné linie odvozené z odrůdy Loken, homozygotní pro různé kombinace alel na třech isozymových lokusech GPI-2, PGM-2 a Est-4. Pokus se uskutečnil na 4 místech (Norsko, Dánsko, ČR a Velká Británie) a zahrnoval 3 bloky parcel se vzdáleností mezi parcelami 15, 30 a 60 m, vzájemně izolovaných různou kulisovou plodinou, založených ve dvou opakováních. Každý blok se skládal z centrální parcely (receptoru), obklopené hexagonem parcel potenciálních zdrojů kontaminace (donorů). Z každé rostliny v centrální parcele bylo analyzováno 7 - 14 semenáčků na allozymové složení a byla odhadnuta kontaminace cizím pylem. Na všech pokusných místech klesala kontaminace se zvětšující se vzdáleností parcel. K redukci kontaminace pod 1 % byla doporučena izolační vzdálenost minimálně 30 m a vysoká kulisová plodina (nejlépe se osvědčilo žito). (cs)
- The objectives of the study were to estimate pollen contamination between field regeneration plots, using different isolation distances and barrier crops, and to suggest acceptable isolation distances in the field. The wind-pollinated species (Festuca pratensis) was used, where 4 distinct populations were available. The populations could be distinguished by being homozygous for different combinations of alleles at three isoenzyme loci: (GPI-2, PGM-2, and Est-4). Each experimental unit involved one central receptor plot surrounded by a hexagon of six donor plots. Field experiments were conducted in Norway, Denmark, the Czech Republic and UK, with three experimental units using an inter-plot distances of 15, 30 and 60 m. All sites used different barrier crops. From each plant in the receptor plots, 7 - 14 seedlings were analyzed to determine their allozyme composition and to estimate the pollen contamination. At all locations the level of contamination decreased with increasing isolation distance. In ca
