Description of Forest Genetic Reources Data base

Forest Trees Genetic Resources Database contains information about forest trees genetic resources selected in situ (identified populations and genetic preserves (156 units), seed populations (205 units), and select (plus) trees (1851 units)), accumulated in ex situ collections – families descendant from scientific research and breeding testing populations (494 units), and about clones (193 units) in clone collections and seed plantation. The accumulated information covers genetic resources of a total of 2899 forest trees.

In terms of species of forest trees, entries of genetic resources are distributed in the database as follows: Quercus petrea Liebl. – 40 units, Populus tremula L. – 141 units, Alnus glutinosa (L) Gaertn. – 452 units, Ulmus glabra Huds – 14 units, Betula pendula Roth. – 507 units, Larix decidua Mill., Larix kaemferi (Lamb.) Carrie – 36 units, Tilia cordata Mill. – 211 units, Pyrus pyraster (L) Burgsd. – 33 units, Malus sylvestris (L) Mill. – 27 units, Fraxinus excelsior L. – 181 units, Quercus robur L. – 455 units, Quercus rubra L. – 1 units, Pinus sylvestris L. – 432 units, Picea abies (L.) Karst. – 327 units, Ulmus laevis Pallas – 42 units

Each unit of genetic resources is given a description contained in several different columns of a table: Lithuanian Forest Seed Base Database ID, Lithuanian Forest Seed Base Database code, resource type (status) code (GD – genetic preserve, SM – seed tree population, PM – select (plus) tree, SE - family, KL – clone); Latin name of botanic species, name of a forest management unit or a company or name of an owner, location name or forestry office name, provenance area, forest quarter No., forest plot No., object area (ha), geographical coordinates (Northern latitude in degrees and minutes, Eastern longitude in degrees and minutes), elevation above the see level, average age of a holt or a tree, and details of a contact person.

On the basis of the first letters or numbers of a code of a descendant family or a clone, the forest management unit or a population, from which the family originated, may be traced, while the last numbers indicate a number of a parent tree of a family in the forest management unit or in Lithuania. In entries related to descendant families and clones, names of forest management units and forestry offices, numbers of quarters and plots, and coordinates mark locations of genotype collections (descendants of trial populations, clone collections or seed plantations). Data on descendant families or clone populations and parent trees are stored in the same database and may be found by the same code of a genetic preserve or of a plus tree in the Lithuanian Forest Seed Base Database.

It is possible to perform a search (filtration of data entries) for genetic resources by a National Registry code, tree species, genetic resource type (status), provenance area, forest management unit or owner, forestry office or place-name or owner.

Output of the information about genetic resources found on a database is presented in a form of a list, including complete description of every resource, listing the entries found in the ascending order of the National Registry code or in the alphabetical order, when the filtering is done by tree species, resource type (status), forest management unit or owner, forestry office or location. Also, an option should be provided to arrange the entries found by any of the descriptors.

Forest Trees Genetic Resources Database contains information about forest trees genetic resources selected in situ (identified populations, genetic preserves, seed populations, and plus trees) and accumulated in ex situ collections – families descendant from scientific research and breeding testing populations, etc. Furthermore, a short description of institutions engaged in preservation of these resources as well as contact information of these institutions are presented. Each entry in this database should be linked to the relevant entries in the Experiments and Experimental Objects Database, Institutions Database, Publications Database, etc. Genetic resources of plants, which have been used or are currently being used for biotechnological research, will be marked in the database.

Each unit of genetic resources is given a description contained in several different columns of a table:

• - Lithuanian Forest Seed Base Database ID,
• - Lithuanian Forest Seed Base Database code,
• - Resource type (status) code: GD – genetic preserve, SM – seed tree population, PM – select (plus) tree, SE - family, KL – clone;
• - Latin name of botanic species,
• - Name of a forest management unit or a company or name of an owner,
• - Location name or forestry office name,
• - Provenance area,
• - Forest quarter No.,
• - Forest plot No.,
• - Object area (ha),
• - Geographical coordinates: Northern latitude in degrees and minutes, Eastern longitude in degrees and minutes,
• - Elevation above the see level,
• - Average age of a holt or a tree,
• - Details of a contact person.

On the basis of the first letters or numbers of a code of a descendant family or a clone, the forest management unit or a population, from which the family originated, may be traced, while the last numbers indicate a number of a parent tree of a family in the forest management unit or in Lithuania. In entries related to descendant families and clones, names of forest management units and forestry offices, numbers of quarters and plots, and coordinates mark locations of genotype collections (descendants of trial populations, clone collections or seed plantations). Data on descendant families or clone populations and parent trees are stored in the same database and may be found by the same code of a genetic preserve or of a plus tree in the Genetic Resources Database.
