A Blueprint for Building Resilience and Food Security in MENA and SSA Drylands: Diversifying Agriculture With Neglected and Underutilized Species

open access: yesFood and Energy Security, Volume 14, Issue 1, January/February 2025.
ABSTRACT Drylands, encompassing 41% of global land and supporting over 2 billion people, face significant challenges, including water scarcity, extreme temperatures, and soil degradation. Dryland spans vast areas of Middle East and North Africa (MENA) and Sub‐Sahara Africa (SSA) regions and poses a threat to food security and resilience.

Trends in genetic gain for yam in the IITA breeding program

open access: yesCrop Science, Volume 64, Issue 4, Page 2261-2273, July/August 2024.
Abstract Monitoring genetic gain is crucial to ensure breeding programs' effectiveness and identify potential challenges and areas for their improvement. Our study provides a first overview of the trends in genetic gain for tuber yield and disease resistance traits in the IITA's (International Institute of Tropical Agriculture) yam breeding program. We

Growth and Nutrient Use Efficiencies of Yams (Dioscorea spp.) Grown in Two Contrasting Soils of West Africa

open access: yesInternational Journal of Agronomy, 2011
Fertilization is an important management strategy of yams (Dioscorea spp.) especially when grown in degraded soils. A field study evaluated the leaf numbers, leaf area indices, crop growth, yields, and nitrogen (N) and potassium (K) use efficiencies of D.

GGE Biplot Analysis of 12 Dioscorea rotundata Genotypes in Ghana

open access: yesJournal of Agricultural Science, 2017
To determine the effects of environment and genotypic differences on tuber yield and other related traits, 12 genotypes comprising 9 improved elite clones, two local landraces and 1 improved and released variety were evaluated for tuber yield, response to yam mosaic virus and leaf spot diseases at 16 growing environments.

Shoot and plantlet regeneration from meristems of Dioscorea rotundata Poir and Dioscorea alata L.

open access: yesAfrican Journal of Biotechnology, 2008
In vitro culture media capable of regenerating moderate to high shoots and/or plantlets from meristems of two yam species – Dioscorea rotundata and Dioscorea alata within comparable duration of 10 weeksas commonly obtained in other monocots and root and tuber crops were investigated.
