![]() ![]() This review assesses the way in which on-farm experimental studies address the scope or generalisability of their findings when based on a limited number of farms. Mauritania cultivars in the Sahel region.Īgronomists have increasingly conducted experiments on-farm, in an attempt to increase the wider applicability (external validity) of their experimental findings and their relevance for agricultural development. The genetic information gathered in this study can be useful for phylogenetic studies, sequencing projects, and domestication programs that focus on controlled pollination for the development of improved Z. ![]() Plants of the germplasm investigated were found to be octoploid with a chromosome number of 2 n = 8 x = 96. The mean, median, minimum, and maximum genome size estimates (1Cx-DNA) of Z. Genome size estimates were determined using flow cytometry, and chromosome count was achieved using chromosome spreads of actively growing root tips. mauritiana germplasm collected from eastern Senegal, West Africa. The purpose of our study was to determine the genome size estimate and chromosome numbers of Z. The plant plays an increasing economic role in the livelihoods of local Sahelian populations, but despite this there is little genetic information about it. ![]() Current domestication programs focus on using the local species as rootstock for the improved imported Asian cultivars to provide tolerance to pests and diseases. is a widespread shrub or tree of the Sahel region, where it grows wild and is used for various purposes, including nutrition, medicine, and firewood. ![]()
