Alectra voegelii is one of the parasitic weeds that threaten groundnut and cow pea production in northern and southern Guinea Savanna of Nigeria. A field trial was conducted in 2014 rainy season at Bayero University, Kano Teaching and Research Farm to evaluate the response of local and improved 11 groundnut (Arachis hypogaea l.) genotypes to naturally infestation of Alectra vogelii (Benth.). The experiment was laid out in randomized complete block design (RCBD) with three replicates. Our data recorded that Samnut 25 had the lowest chlorophyll content and canopy temperature while a local variety "Sabiya" had the highest chlorop'hyll content and canopy temperature. However, both varieties recorded the highest and lowest Alectra infestation respectively. ~rrelation analysis revealed a negative interaction between leaf area index (LAI) and canopy temperature at 70 days after sowing and Alectra infestation at 70 days after emergence among the groundnut genotypes. Further screening should be conducted to identify a resistantand susceptible genotypes.
