Effects of Low Nitrogen and Drought on Genetic Parameters of Grain Yield and Endosperm Hardness of Quality Protein Maize

Combining ability for grain yield and silking of maize inbred lines derived from three open pollinated varieties released for mid altitudes of Rwanda: Comparison of Diallel and North Carolina Design II

“…There are two independent estimations of GCA that allow determination of the maternal effects indicated by the deference between GCA female parents and GCA male parents. The GCA of male parents is free from maternal effects and represents the real additive effects (Ngaboyisonga et al, 2008).…”

“…Furthermore, they have been widely applied to other crops such as rice, wheat and potato (Asfaliza et al, 2012;Kumar et al, 2017;Terres et al, 2017). Moreover, the NCDII has been utilised to estimate both combing abilities and components of variance (Ngaboyisonga et al, 2008;Khattab et al, 2011;Narayanamma et al, 2013;Salami and Ogbowuro, 2016). Furthermore, the NCDII have been utilised on other crops for various genetic studies.…”

Inheritance of kernel quality attributes in quality protein maize (Zea maysL.)

“…Number of kernels corresponding to each class was counted and mean modification score of each entry were calculated for each replication and were averaged over replication. Endosperm modification score was calculated following Ngaboyisonga et al (2009).…”

Registration of Temperate Quality Protein Maize (QPM) Lines BQPM9, BQPM10, BQPM11, BQPM12, BQPM13, BQPM14, BQPM15, BQPM16, and BQPM17

“…Despite progress in adapting these QPM lines to various environments, there is little documentation for QPM lines that are well‐adapted to the US Corn Belt (Zarkadas et al, 2000; Bhatnagar et al, 2004; Ngaboyisonga et al, 2009). Our goal was to develop temperate QPM lines that were well‐adapted to the US Corn Belt.…”
