\u00a0<\/strong>Le travail a pour objectif l\u2019\u00e9tude du r\u00f4le de quelques param\u00e8tres ph\u00e9nologiques et morphologiques comme la p\u00e9riode v\u00e9g\u00e9tative, la biomasse a\u00e9rienne et la hauteur de la chaume dans la s\u00e9lection d\u2019une vingtaine de g\u00e9notypes de bl\u00e9 dur (Triticum durum<\/u><\/em> Desf.) dans la zone semi-aride.<\/p>\n

La pr\u00e9sente \u00e9tude a \u00e9t\u00e9 conduite au cours de l\u2019ann\u00e9e 2002\/ 2003, \u00e0 l\u2019ITGC de S\u00e9tif et de l\u2019ITCMI d\u2019Oum El Bouaghi. Le dispositif exp\u00e9rimental adopt\u00e9 \u00e9tait en blocs \u00a0al\u00e9atoire complet.<\/p>\n

Les mesures ont port\u00e9 sur la biomasse a\u00e9rienne au stade \u00e9piaison, la dur\u00e9e de la phase v\u00e9g\u00e9tative, le rendement et ses composantes.<\/p>\n

Les r\u00e9sultats montrent que le rendement \u00e9lev\u00e9 est d\u00fb au nombre de grains par m\u00e8tre carr\u00e9, et \u00e0 la hauteur de la chaume. La biomasse a\u00e9rienne et l\u2019indice de r\u00e9colte de par leurs effets directs assez \u00e9lev\u00e9s participent \u00e0 l\u2019\u00e9laboration du rendement.<\/p>\n

Les param\u00e8tres morpho-ph\u00e9nologiques peuvent \u00eatre des indicateurs positifs pour la production de la culture de bl\u00e9 et peuvent \u00eatre pris en compte pour une s\u00e9lection plus pertinente de vari\u00e9t\u00e9s adapt\u00e9es aux conditions semi-arides.<\/p>\n

Mots cl\u00e9s<\/strong>\u00a0: bl\u00e9 dur (Triticum durum<\/u>), adaptation, biomasse, hauteur des chaumes, indice de r\u00e9colte, semi-aride.<\/em><\/p>\n
