La plupart des vari\u00e9t\u00e9s connues au d\u00e9but du XXe si\u00e8cle ont disparu. Les vari\u00e9t\u00e9s nouvelles sont le plus souvent hybrides<\/strong>, ce qui veut dire qu\u2019elles sont issues du croisement de deux parents de la m\u00eame esp\u00e8ce mais au patrimoine g\u00e9n\u00e9tique diff\u00e9rent et compl\u00e9mentaire.\u00a0Cela les rend\u00a0plus r\u00e9sistantes \u00e0 la s\u00e9cheresse et au gel par exemple\u00a0; plus grosses, plus color\u00e9es ou plus faciles \u00e0 cultiver.<\/span><\/p>\n

Mais le consommateur y perd du go\u00fbt\u00a0\u00a0et, surtout, cette chute de biodiversit\u00e9\u00a0rend\u00a0les cultures tr\u00e8s vuln\u00e9rables face \u00e0 un nouveau ravageur<\/strong> ou une nouvelle maladie\u00a0: il suffit d\u2019un plant affect\u00e9 pour qu\u2019ils se r\u00e9pandent facilement dans tout un champ.<\/span><\/p>\n

L\u2019association Graines de vie<\/strong> ne vous laisse pas sur votre faim et\u00a0raconte\u00a0sur son site (www.grainesdevie.org ) les passionnantes histoires des l\u00e9gumes qu\u2019elle veut pr\u00e9server, du haricot du Saint Sacrement au potiron bleu de Hongrie en passant par la sucrine du Berry\u00a0.<\/strong><\/span><\/p>\n
