Genotype × Environment Interaction of Carotene Content of Yellow-Fleshed Cassava Genotypes in Nigeria
Cassava is an important starchy root crop and a major staple for more than 70 million people in Nigeria. New yellow-fleshed genotypes are being developed to combat vitamin A deficiency. Trials of 18 yellow-fleshed genotypes and two officially released white-fleshed clones, used as checks for 2008/2009 and 2009/2010 seasons in five major cassava growing agroecological zones of Nigeria. The trial locations were Ikenne (humid forest), Ibadan (forest-savanna transition), Ubiaja (subhumid forest), Mokwa (southern Guinea savanna) and Zaria (northern Guinea savanna). At each location, the trial was established in a randomized complete block design with four replications. The objective of the study was to assess genotype performance and genotype × environment interaction for total carotene concentration (TCC), total carotene content per root (TC-R), and total carotene content per plant (TC-P). Significant differences (P
