Can parentage analysis facilitate breeding activities in root and tuber crops?

Autor: Norman, P.E. Asfaw, A. Tongoona, P.B. Danquah, A. Danquah, E.Y. Koeyer, D. de Asiedu, Robert

Controlled pollination in root and tuber crops is challenging. Complex ploidy, cross-incompatibility, erratic flowering patterns, outcrossing, etc., limit the efficiency of breeding progress in these crops. Half-sib breeding that involves random pollination among parents is a viable method to har...

Pollination success in some white yam genotypes under polycross and nested mating designs

Autor: Norman, P.E. Asfaw, A. Tongoona, P.B. Danquah, A.O. Danquah, E.Y. Koeyer, D. de Asiedu, Robert

Breeding yams is a two-step process that combines sexual and asexual reproduction. Sexual reproduction involving a transfer of pollen from male to female genotype reproductive organ is a key step to generate variability in yam improvement. The efficacy of genetic improvement therefore depends on ...

Effect of staking and non-staking systems on disease severity, yield and quality attributes of yams (Dioscorea alata)

Autor: Norman, P.E. Whyte, J.B.A. Samura, A.E. Massaquoi, A. Sesay, L. Dixon, Alfred G.O. Fomba, S.N. Benya, M.T. Sowa, M.M.

Aims: The aim of this study was to evaluate the effect of staking and non-staking systems on disease severity, yield and quality attributes of yams. Methodology: High costs and lack of planting materials, labour, staking and inappropriate knowledge on production techniques are major constraints o...
