Relationships among traits of tropical early maize cultivars in contrasting environments

Autor: Badu-Apraku, B. Akinwale, R.O. Ajala, S.O. Menkir, A. Fakorede, M.A.B. Oyekunle, M.

Secondary traits can improve precision with which drought or low soil nitrogen (low-N) tolerant maize (Zea mays L.) genotypes are identified, compared to measuring only grain yield under each stress. The objective of this study was to identify secondary traits for indirect selection for yield imp...

Biplot analysis of line X tester data of maize (Zea mays L.) inbred lines under stress and nonstress environments

Autor: Badu-Apraku, B. Akinwale, R.O.

The GGE biplot tool has potential for determining combining ability effects, identifying distinct heterotic groups and efficient testers in a line × tester study. However, its use for such analysis has not been adequately explored. The objectives of this study were to (i) assess combining ability...

Combining ability of earlymaturing white maize inbreds under stress and nonstress environments

Autor: Badu-Apraku, B. Oyekunle, M. Akinwale, R.O. Lum, A.F.

Maize (Zea mays L.) hybrids resistant to Striga hermonthica (Del) Benth and tolerant to drought are vital to the sustainability of productivity of the maize-based farming systems of West and Central Africa (WCA). Thirty-six diallel crosses derived from nine early maturing white maize inbreds were...

Genetic analysis of drought-adaptive traits at seedling stage in early-maturing maize inbred lines and field performance under stress conditions

Autor: Adewale, S.A. Akinwale, R.O. Fakorede, M.A.B. Badu-Apraku, B.

Maize hybrids that are tolerant to drought at the seedling stage are needed to boost productivity in the rainforest agro-ecology of West Africa. Genetics of tolerance of maize seedling to drought stress is not well understood and is poorly documented. The objectives of this study were to screen e...

Relative changes in genetic variability and correlations in an earlymaturing maize population during recurrent selection

Autor: Badu-Apraku, B. Akinwale, R.O. Fakorede, M.A.B. Oyekunle, M. Franco, J.

Four cycles of S1 family recurrent selection to improve grain yield and resistance to Striga hermonthica have been completed in TZE-Y Pop STR C0. In order to determine whether or not to continue with the recurrent scheme, it was desirable to evaluate the amount of residual genetic variance and as...
