Description Semi-arid and subhumid West Africa is characterized by high inter-annual rainfall
variability, with variable onset of the rainy season, somewhat more predictable
endings, and drought or excess water occurrence at any time during the
growing season. Climate change is predicted to increase this variability. This article
summarizes options for plant breeders to enhance the adaptation of pearl millet
(Pennisetum glaucum [L.] R. Br.) and sorghum (Sorghum bicolor [L.] Moench)
to climate variability in West Africa. Developing variety types with high degrees
of heterozygosity and genetic heterogeneity for adaptation traits helps achieving
better individual and population buffering capacity. Traits that potentially
enhance adaptive phenotypic plasticity or yield stability in variable climates
include photoperiod-sensitive flowering, plastic tillering, flooding tolerance,
seedling heat tolerance and phosphorus efficiency. Farmer-participatory dynamic
gene pool management using broad-based populations and diverse selection
environments is useful to develop new diverse germplasm adapted to specific
production constraints including climate variability. For sustainable productivity
increase, improved cultivars should respond to farmer-adoptable soil fertility
management and water harvesting techniques. Larger-scale, on-farm participatory
testing will enable assessments of varietal performance under evolving climatic
variability, provide perspective on needs and opportunities and enhance
adoption. Strengthening seed systems will be required to achieve sustainable
impacts.
