Current status and conservation of Pistacia germplasm
Biotechnology Advances, 2010The genetic erosion of Pistacia germplasm has been highlighted in many reports. In order to emphasize this and to focus more attention on this subject, national and international (especially IPGRI and IFAR) institutions have initiated projects proposing to characterize, collect and conserve Pistacia germplasm.

Germplasm Resources: Diversity and Conservation
2021Coconut, Cocos nucifera L., is a monospecific palm in the genus Cocos under the subtribe Attaleinae, is widely distributed in the coastal tropics, and is regarded as a semi-domesticated species. In the absence of truly wild forms and no known wild relatives, the origin of the coconut palm has been postulated based on historical accounts and fossil ...

IN VITRO GERMPLASM CONSERVATION
Acta Horticulturae, 1998In vitro techniques have great potential for collecting, exchange and conservation of: i) genetic resources of recalcitrant-seed and vegetatively propagated species as well as of endangered species; ii) elite genotypes which are multiplied on a large scale in production laboratories; iii) cultures with special attributes, eg, metabolite-producing cell ...

In Vitro Conservation of Plant Germplasm
2015Biotechnology has brought about a revolution in the way that plant genetic resources can be utilized. Clonal crops cover a wide range of species from the root and tuber crops, such as potato, cassava, yam, taro and sweet potato, to fruits, such as apple, pear, citrus, banana and the cooking banana (plantain). Other miscellaneous crops including vanilla,

Germplasm Resources and Conservation
1987In earlier chapters, procedures were discussed by which plant breeders could extend the range of genetic variability in crop plants. These processes—gene recombination, polyploidy, and mutation—are not new innovations. They extend the natural forces by which present cultivated crop species have evolved and reached the forms in which we know them today.

Conservation of Germplasm in Forest Trees
1993Forest trees meet human needs and contribute to natural ecosystems in unique and diverse ways. As a source of fuel and fiber, they are important commodities. As dominant members of many natural ecosystems, they play keystone ecological roles in plant and animal communities.

Pear Germplasm Needs and Conservation
2019Pear (Pyrus) species are sources of food, drink, landscape trees, and rootstocks. Different Pyrus species possess varied genetic traits that render them useful for diverse purposes. Pear genebanks preserve cultivars, or unique genotypes, as grafted trees.

Conservation and Access to Sugarbeet Germplasm
Sugar Tech, 2010Conservation of the genetic resources of sugar beet has been considered a task of genebanks which collect, reproduce and preserve seed samples under cold storage conditions ex situ. Arguments are provided why the ex situ conservation of beet germplasm may not be fully sufficient to maintain the genetic diversity of beet genetic resources on the long ...

Evaluation, Maintenance, and Conservation of Germplasm
2007Germplasm resources constitute the building blocks of crop improvement program. These provide basic raw material and reservoir of genes for breeding high‐yielding and disease‐resistant cultivars/varieties/hybrids. It is believed that the genus Brassica has Mediterranean origin from where it spread to African and Asian countries.
