Status of the Global Cotton Germplasm Resources

Cotton Germplasm Collection of Uzbekistan

“…No long term cold storage (-20 or-80 °C) facilities, requiring attention and investment, are available for any of the germplasm collections in Uzbekistan, as highlighted by Campbell et al [3] and Abdullaev et al [8].…”

“…Consequently, germplasm resources, in particular those without short term cold room facility, are scheduled for seed renewal every 8-10 years under forced self-pollination in the open field conditions [3]. Each organization has its own, but very similar protocols, schemes of planting, growing and evaluating germplasm (see [8] for detailed protocol for IG&PEB cotton collection), government research grants and field extension stations with up to 8-10 staff working on germplasm maintenance.…”

“…As reported by Campbell et al [3], all germplasm related activities and maintenance of the Uzbekistan cotton collections are funded by the Committee for Coordination of Science and Technology Development under the Cabinet of Ministry of Uzbekistan, MAWR, and ASUz where funds are given as competitive research and "a unique facility" maintenance grants. Moreover, each institution receives international grants for projects that utilize the germplasm resources, and therefore, budget funding for germplasm related works [3].…”

Biodiversity Measures in Agriculture Using DNA

“…The continuous procedure causes loss of general biological diversity (Bai & Lindhout, 2007) and genetic diversity, which can be noticed by a loss in allele richness. The gains achieved by plant breeding may decrease in years of selection due to the loss of genetic richness and allele segregation within the breeding population (Campbell et al, 2010). How genetic variability could be enhanced or preserved?…”
