In-Vitro Determination of Kernel Resistance to Aspergillus flavus and Aflatoxin Accumulation in Groundnut

The study determined the level of resistance to Aspergillus flavus and to accumulation of aflatoxins in potential new breeding sources from ICRISAT Mali and in locally adapted groundnut genotypes commonly grown by Ugandan farmers. Genotypes were significantly different in their responses to A. flavus and to aflatoxin accumulation at P<0.001. Locally adapted genotypes that had both low A.flavus and accumulation of aflatoxins included Serenut 4, AGRA 99044 and erudu red, while AGRA 99033, Serenut 2, acholi white and red beauty had the highest levels of A.flavus and aflatoxin accumulations. High level of variations in the genotypes can be further used for genetic studies in order to establish effective and efficient breeding strategy for resistance to A.flavus and to the accumulation of aflatoxins in Ugandan lines.
L’étude a déterminé le degré de résistance à Aspergillus flavus et à l’accumulation des aflatoxines dans les sources potentielles de nouvelle reproduction de l’ICRISAT au Mali et dans les génotypes d’arachides adaptés aux conditions locales couramment cultivés par les agriculteurs ougandais. Les génotypes étaient significativement différents dans leurs réponses à A. flavus et à l’accumulation des aflatoxines à P <0,001. Les génotypes adaptées aux conditions locales, qui avaient à la fois l’A.flavus faible et l’accumulation d’aflatoxines faible incluaient Serenut 4, AGRA 99044 et erudu rouge, tandis que l’AGRA 99033, Serenut 2, Acholi blanc et la beauté rouge avaient les plus hauts niveaux d’A. flavus et d’accumulations des aflatoxines. Le niveau élevé de variations dans les génotypes peut être en outre utilisé pour des études génétiques afin d’établir la stratégie de reproduction efficace et efficiente pour la résistance à A. flavus et à l’accumulation des aflatoxines dans les lignes ougandaises.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.  This record contains an extended abstract accepted under the theme of Crop Improvement.
