Working Document Series Open Access Genetic Analysis of Tropical Maize Inbreds and Hybrids for Grain Yield and Traits Associated with Drought Tolerance P. Gibson · C. Magorokosho · X. Mhike · P. Okori Drought tolerance is a complex trait, hence genetic improvement of this trait in maize requires indirect selection methods based on highly heritable traits that correlate strongly with grain yield. This study aimed at determining the modes… RUF-32504 2012 CC BY 4.0 17 May 2014
