Heterosis and combining abilities for multiple resistance to Turcicum leaf blight and maize streak virus
Abstract

Fifty two single crosses were evaluated for resistance to
Turcicum Leaf blight (TLB) and Maize Streak Virus (MSV)
resistance across several locations in Uganda in 2009. The
crosses were grown in 1-row plots with 2 replications.
Subsequently108 triple crosses from the 54 F1s were evaluated
in 2-row plots for both diseases and agronomic performance in
multi-environments during the second season of 2009.
Genotypes were considered fixed and environment random.
GCA and SCA effects were significantly different among
parents and among crosses. Interactions of Environment with
GCA and SCA were significant for both TLB and MSV. Plant
height and yield were also significantly affected by Crosses x
Environment interaction.
