The genetic diversity of wild and cultivated cornflower populations: implications for conservation
International audience; The cornflower, Cyanus segetum Hill, 1762 (formerly Centaurea cyanus L.) is an iconic arable plantthat was historically widespread in Western Europe, but has shown a marked demographic declinesince the mid-20th century. The species is distinctively attractive due to its large blue-colouredflowers and is an important source of nectar for pollinating insects. For these reasons, populationsfrom horticultural or cultivated origins are frequently sown within flower fallows and flower strips.However, cultivated populations may be of non-local origin and have a reduced and/or divergentgenetic variation. Therefore, replacement of local populations by cultivated ones or gene …
