“…The performance of yield and yield related traits of the varieties in this experiment was similar to many of previous works (Sorsa et al, 2014;Bello et al, 2012;Tulu et al, 2001;Hussain et al, 2006). In similar way, Martins et al (2010) reported that QPM is best in nutritional aspect as well as in its high yielding ability compared to the normal maize.…”

“…As it is observed in the preliminary ANOVA and mean comparison analysis (Appendix 1 and Table 1 and 2), the variation was significant for the following traits such as plant height, root height, grain yield, biomass and kernels per ear. These differences are similar with the findings of Sorsa et al (2014). The mean of plant height was 243.94 cm and the highest plant height was 265.9 cm.…”

This study was conducted with the aim of evaluating the performance of released quality protein maize varieties in the lowlands of Wolaita Zone, southern Ethiopia in 2014. As treatment, four varieties; BH540, MelkassaQ4, MelkassaQ6 and MHQ138 was planted in the complete randomized block design with three replications in two locations including Humbo and Badessa. In the 2014, growing season there was shortage and uneven distribution of rainfall compared to the relative normal distribution of rainfall in the lowlands of study area. Analysis of variance and mean comparison results prevailed the presence of significant difference (p<0.05) for some of the studied traits. These traits are plant height, root height, grain yield, biomass and kernels per ear. Plant height was negatively (r =-0.18 and r =-0.12) correlated with ear height and root height respectively and positively with low value correlated (r = 0.042) with grain yield. Similarly root height was strongly correlated with grain yield and biomass (r = 0.24 and r = 0.35) in the positive direction. Regarding the yield performance, from three QPM varieties, MHQ138 performed better than that of others and the check BH540.
