Host Crop Reaction and Genotypes at Mokwa and Shonga in Savanna
Abstract
Field trials were conducted on the farms of Niger State College of Agriculture, Mokwa (09 18 N; 05 04 E), National01Cereals Research Institute Bida (09 45 N; 06 07 E) and Emir of Shonga (08 29 N; 04 35 E) in 2004, 2005 and 2006 wet seasons trials to the effect of Striga hermonthica 0n the performance of three genotypes each of three host crops, The genotypes were 9022–13, Acr. 97 TZL Comp. 1-W and 8338-1 for maize, FARO 40, WAB 56–50 and FARO 45 for rice and SAMSORG 3, ICSV 111 and SAMSORG 1 for sorghum with and without Striga infestation. constituted the treatments were laid out in a randomized complete block design replicated four times. The results indicated that the genotypes of maize (9022–13 and Acr. 97 TZL Comp.1-W), rice (FARO 40 and WAB 56–50) and sorghum (SAMSORG 3) exhibited various levels of resistance/tolerance to Striga parasitism through support for lower infestation and incidence of the weed, exhibition of lower reaction syndrome and higher crop growth vigour as well as production of higher grain yield than the other respective varieties. Parasitism of host crops followed the order Mokwa > Bida > Shonga at different locations in the trial.
