[Bean varietal development and breeding in Zaire]
1991
Nkonko T, M.
From the advanced trials of varietal selection in Mulungu the eight best bush varieties and the eight best climbing varieties have been selected for on-farm testing. On-farm variety trials of the preceding cycle have shown some promising varieties, but none of them proved to be clearly superior to the local check. An observation trial at four research sites with material originating from the IBYAN, showed that there are big differences in productivity and vegetative cycle between the different sites. A list with the most productive bush and climbing varieties identified so far, is presented for each site. (AS)
