A
new EC-funded project has been set up to stimulate the use of
rare genebank material in leafy vegetable production.
The most important European leafy
vegetables are lettuce, spinach and chicory but the minor crops
of lamb's lettuce and rocket (rucola) are also becoming
increasingly important, especially with the trend towards more
sales of bagged mixed salads. A network has been established of
14 partners from 10 European countries that brings together
genebanks, universities, research institutes and NGO's active in
conservation and utilisation of the genetic resources of these
crops. The project is coordinated by Chris Kik from the
Centre for Genetic
Resources (CGN), Wageningen, the
Netherlands.
The potential is huge, over 8,400
accessions of lettuce alone are held in genebanks and living
collections by project partners across Europe.
Spinach and chicory have more than 900
accessions each and there is a total of 270 accessions of rocket
and lamb's lettuce. The task is to characterise more than 1200
of these accessions and to develop the databases of these crops
to improve access and utilisation of the collections. Evaluation
of important characteristics of more than 750 accessions will
allow breeders to use the most promising germplasm in their
programs to develop improved materials. Promising sources of
resistance to pests and diseases will be used to develop
varieties less demanding of fungicides and pesticides. The
selection of improved and more attractive varieties should
stimulate consumption of these healthy vegetables. Parts of the
collections will also be evaluated for nitrates, oxalic acid and
glucosinolates, which can have negative effects on health.
