Out of 24 explored towns, in 8, landraces were grown and in all, instances seeds could be obtained. Fifty-three accessions from different crop species were collected in 17 sites, belonging to 10 botanical families, of which solanaceae was the most represented （32%）, followed by fabaceae （17%）, cueurbitaceae （11%） and alliaceae and brassicaceae （9%）. As expected, vegetable crops were the most collected, reaching a value as 58.5%, spices 20.8%, while pulses 15.1% and cereals 5.7% of the total. This collecting mission showed that in internal areas of Romania, germplasm of old landraces of many vegetable and crop species still survive, and indicated the urgency to continue also in other agricultural districts of Romania.展开更多

In totality, 50 accessions belonging to 14 taxa were collected from 8 collecting sites, representing mainly highly variable old landraces of vegetables and cereals and, especially, of pulses; most of them that appear severely threatened by genetic erosion are still cultivated, at certain level, by old farmers and directly used by their families. A comparison of the results of the previous missions that have been carried out in Calabria region that preserve valuable crop genetic resources on farm shows the large degree of genetic erosion for all crops collected. The results stressed the need to conserve a considerable amount of material endangered and the necessity of our ongoing care for their preservation either on farms or ex situ in genebanks. The complementarity of both conservation methods is needed.展开更多
