  1. 21. Morphological characterisation and cryopreservation of sweet potato, Ipomoea batatas (L.) Lam., accessions at the NPGRC of South Africa

    University essay from SLU/Swedish Biodiversity Centre

    Author : Machoene Tshidi Manamela; [2009]
    Keywords : cryopreservation; duplicate accessions; germplasm; morphological characterisation; NPGRC; phenotypic diversity; sweet potato ; South Africa;

    Abstract : Morphological characterisation of germplasm helps in the identification of duplicate accessions, unique traits and the development of core collection. Cryopreservation serves as a complementary conservation method to field and in-vitro methods. READ MORE

  3. 22. Latitudinal patterns in body size of Roesel’s bush cricketMetrioptera roeselii within and outside the continuous area of its distribution

    University essay from SLU/Dept. of Ecology

    Author : Frida Holma; [2009]
    Keywords : Metrioptera roeselii; inbreeding depression; latitudinal pattern;

    Abstract : Over time, species colonize new areas naturally or through humans. The colonizers areoften few and founded populations represent only a fraction of the genetic diversityexisting in the original population. READ MORE

  4. 23. Morphological characterisation of sorghum (Sorghum bicolor) diversity in Burundi

    University essay from SLU/Swedish Biodiversity Centre

    Author : Espérance Habindavyi; [2009]
    Keywords : Burundi; landraces; morphological traits; variability; Sorghum bicolor;

    Abstract : Sorghum (Sorghum bicolor (L.)Moench), is a cereal crop close to maize and sugar cane. The crop originated in the Northeast part of Africa and has been an important crop in many dry areas of tropical countries. Sorghum is used for beverage and porridge for many people of Africa.

  5. 24. Maize (Zea mays L.) landraces in eastern Serbia : characterization and the present cultivation

    University essay from SLU/Swedish Biodiversity Centre

    Author : Jelena Knežević; [2009]
    Keywords : maize; Zea mays; local varieties; characterization; conservation; zein proteins; electrophoresis; field survey; interviews; ethnobotany; Serbia;

    Abstract : The evolutionary value of landraces is immense, especially when bearing in mind the constant diminishment of crop genetic variability and the development of intensive agriculture. The assessment of morphological and agronomic traits of landraces, together with molecular markers, is certainly a good basis for the efforts toward their protection. READ MORE

  6. 25. Analysis of Swedish accessions of Phaseolus vulgaris L. using SSR Markers

    University essay from SLU/Plant Breeding and Biotechnology (until 121231)

    Author : Elin Bengtsson; [2009]
    Keywords : accession; duplicate; garden bean; gene bank; genetic diversity; genetic resources; germplasm; microsatellites; morphological markers; Phaseolus vulgaris; preservation; SSR;

    Abstract : AbstractThe genetic diversity in cultural plants is considered to be threatened due to global climate change and antropogenic influence. Unknowing of future conditions for cultivation, gene banks all over the world are now trying to build up costly safety nets of species and varieties that may become highly valuable owing to their specific traits and genetic heredity.
