Rudolph Shirima.<\/p>\n\n<\/div>\nSa pr\u00e9sentation intitul\u00e9e \u201c Assessment of the degeneration rates of selected cassava varieties under high cassava virus pressure in Coastal Tanzania \u201d a \u00e9t\u00e9 d\u00e9clar\u00e9e meilleure pr\u00e9sentation parmi plus de 50 communications orales.\n\nL'\u00e9tude de Shirima cherche \u00e0 d\u00e9terminer le nombre de fois que les agriculteurs peuvent r\u00e9utiliser leurs boutures de manioc tout en obtenant un bon rendement avant qu'elles ne soient d\u00e9truites par la virose de la mosa\u00efque et de la striure brune du manioc (CBSD) et qu'ils ne doivent acheter de nouveau mat\u00e9riel v\u00e9g\u00e9tal sain. La CBSD constitue une menace majeure pour la production de manioc dans certaines r\u00e9gions d'Afrique.\n\nSelon Rudolph, il \u00e9tudie la d\u00e9g\u00e9n\u00e9rescence de sept vari\u00e9t\u00e9s : un clone (KBH2002_135) et six vari\u00e9t\u00e9s de manioc (Chereko, Kikombe, Kipusa, Kiroba, Kizimbani, Mkuranga-1). Parmi celles-ci, cinq sont des vari\u00e9t\u00e9s \u00e9lites dot\u00e9es d'une bonne r\u00e9sistance \u00e0 la CBSD.\n\n\u201c Ce prix a \u00e9t\u00e9 tr\u00e8s inspirant. C'\u00e9tait un moment \u00e0 la fois choquant et exaltant. C'est la premi\u00e8re fois que je re\u00e7ois cette distinction \u201d, a d\u00e9clar\u00e9 Shirima.\n\nIl a indiqu\u00e9 que ce prix n'\u00e9tait pas seulement le fruit de ses efforts, mais aussi d'un travail d'\u00e9quipe qui a jou\u00e9 un r\u00f4le primordial dans la mise en \u0153uvre et la r\u00e9ussite de l'\u00e9tude.\n\nIl a en outre salu\u00e9 l'approche adopt\u00e9e par l'ISTRC-AB pour aider les jeunes scientifiques \u00e0 participer pleinement \u00e0 l'\u00e9v\u00e9nement, ce qui, selon lui, constitue une excellente pr\u00e9paration pour devenir de jeunes scientifiques comp\u00e9tents en Afrique.\n\n\u201c C'est la deuxi\u00e8me fois que je participe \u00e0 une conf\u00e9rence de l'ISTRC-AB. Ces conf\u00e9rences offrent des opportunit\u00e9s d'\u00e9volution aux jeunes chercheurs \u201d, a-t-il d\u00e9clar\u00e9.\n\nShirima pr\u00e9pare actuellement son doctorat au d\u00e9partement de biologie mol\u00e9culaire et de biotechnologie (MBB) de l'Universit\u00e9 de Dar es-Salaam, avec le soutien du projet \u00ab New Cassava varieties and Clean Seed to Combat CBSD and CMD \u00bb (5CP), dirig\u00e9 par l'IITA.\n
