Re-defining the yam (Dioscorea spp.) core collection using morphological traits

Autor: Girma Tessema, G. Bhattacharjee, R. López Montes, A. Gueye, B. Ofodile, S. Franco, J. Abberton, M.T.

Development of core collection representing the diversity in the entire germplasm creates a better access and enhanced utilization of the main collection thus allowing rapid evaluation in crop improvement programs. Core collections are dynamic in nature and needs revisiting when additional germpl...

Improvement of accession distinctiveness as an added value to the global worth of the yam (Dioscorea spp) genebank

Autor: Girma Tessema, G. Korie, S. Dumet, D. Franco, J.

Misidentification of accessions is a common problem in genebanks. Along the years, mistakes accumulate and this is particularly true when dealing with a large number of accessions requiring annual regeneration. Human errors such as mislabeling or misreading and material mix up during planting or ...

Genetic diversity of tropical maize inbred lines combining resistance to Striga hermonthica with drought tolerance using SNP markers

Autor: Mengesha, W. Menkir, A. Unachukwu, N.N. Meseka, S.K. Farinola, A. Girma Tessema, G. Gedil, M.

Striga hermonthica and drought are the major stresses limiting maize yields in sub-Saharan Africa. The search for diverse maize lines’ tolerance to drought and resistance to S. hermonthica (DTSTHR) is very crucial for yield improvement in areas affected by the two stresses. Understanding the gene...

Yam breeding at IITA: achievements, challenges, and prospects

Autor: López Montes, A. Bhattacharjee, R. Girma Tessema, G.

African food system Yam (Dioscorea spp.) is a multispecies, clonally propagated crop cultivated for its starchy tubers. About 10 species are widely cultivated around the world, but only D. rotundata, D. alata, and D. cayenensis are the most widely cultivated species in West Africa, accounting for...
