  2. Tree breeding - Wikipedia

    en.wikipedia.org/wiki/Tree_breeding

    Tree breeding is the application of genetic, reproductive biology and economics principles to the genetic improvement and management of forest trees. In contrast to the selective breeding of livestock, arable crops, and horticultural flowers over the last few centuries, the breeding of trees, with the exception of fruit trees, is a relatively recent occurrence.

  3. Seed orchard - Wikipedia

    en.wikipedia.org/wiki/Seed_orchard

    As supporting tree breeding make advances, new seed orchards will be genetically better than old ones. This is a relevant factor for the economic lifetime of a seed orchard. Considerations for Swedish Scots pine suggested an economic lifetime of 30 years, which is less than the current lifetime. [6]

  7. Double-pair mating - Wikipedia

    en.wikipedia.org/wiki/Double-pair_mating

    In comparison with single pair mating, DPM has the advantages that the genes from the individual are transmitted to next generation even if one of the crosses fails; that safer estimates of breeding values of the parents get possible (useful for seed orchards, where tested trees are preferred); and that genes from different ancestors have a ...

  8. Vegetative reproduction - Wikipedia

    en.wikipedia.org/wiki/Vegetative_reproduction

    Adventitious roots develop from the underground part of the plant, which is known as the layer. This method of vegetative reproduction also occurs naturally. Another similar method, air layering, involved the scraping and replanting of tree branches which develop into trees. Examples are Jasmine and Bougainvillea.

  9. Plant genetics - Wikipedia

    en.wikipedia.org/wiki/Plant_genetics

    An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
