Innovative breeding research project underpins the value of genetic reserves
(A note by Lothar Frese and Gina Capistrano-Gossmann)
“Crop wild relative populations of Beta vulgaris allow direct mapping of agronomically important genes” is the title of a paper recently published in Nature Communications (Capistrano-Gossmann et al. 2017). The researchers used two CWR populations of Beta vulgaris subsp. maritima for fine mapping and rapid identification of a Rhizomania resistance gene. [read more] (38,5 KB)

Update on Beta nana studies
Little was known about the conservation status and properties of Beta nana in 1993 as noted in the Greek report presented at the 3rd International Beta Genetic Resources Workshop held at the North Dakota State University, Fargo, USA. Since then B. nana stayed on the agenda of the Working Group which recommended in 1999 to include B. nana into in situ conservation projects. It took five years to organize a B. nana plant exploration mission which allowed a team of US-American, Greek and German experts to collect research material in 2005. Seed increase of the collected germplasm followed and in parallel the search for polymorphic microsatellite marker began. In addition, the Greek Genebank implemented two other missions in 2007 and in 2012 on Olympus Mountain for monitoring and recording the demographic parameters of the target populations, which were accompanied by field observations and measurements of the ecological environment. The investigation of the genetic population structure in the alpine B. nana has been completed by scientists of the United States Department of Agriculture, Agricultural Research Service (USDA-ARS), recently. A paper was submitted for publication in 2017 and will hopefully become available soon. The work on B. nana is another evidence for the continued, engaged and trusting cooperation between partners of an international network of Beta experts initiated by the ECPGR at Wageningen, The Netherlands, 30 years ago in November 1987.

Background information

The Third meeting of the Technical Consultative Committee of ECPGR, Reykjavík, Iceland, 1985, had recommended that ECPGR enhance collaborative activities for Beta, in its third Phase. Consequently, in 1987, a Beta workshop was convened at the Centre for Plant Genetic Resources, Wageningen, The Netherlands, in order to develop a collaborative programme on Beta genetic resources. In 1989, IPGRI launched the concept of self-sustaining crop networks.
The World Beta Network (WBN), which was founded the same year, served as a model crop within the framework of the new concept. The goal of all crop-specific networks is to improve international collaboration between curators of collections and researchers and users of germplasm and to enable maximum use of the often limited funds for conservation and utilization through task sharing. The WBN is a voluntary association receiving scientific input and financial support from various partners from the public and commercial sectors. WBN has been instrumental in facilitating progress of research on the genus Beta and the utilization of exotic germplasm.

The ECPGR Working Group on Beta was established in 1998, in order to improve the joint management of European Beta collections and the involvement of their curators in international activities. This Working Group is seen as an integral part of the WBN, improving the function of this international network.
