The International Institute of Tropical Agriculture houses the largest collection of cowpea landraces in the world. This collection has been studied using agro morphological, botanical and geographic descriptors to define a core collection with a smaller reference collection being defined thereaf...

Cryopreservation via droplet vitrification showed high efficiency for cassava meristems (79% average recovery) when these were excised from in vitro seedlings. The efficiency of the process dropped considerably (to >23%) when meristems were excised from field-grown plants, thus precluding the use...

Striga hermonthica (Del.) Benth. is a widespread parasitic weed that infl icts damage on maize (Zea mays L.) in sub-Saharan Africa. This is a highly variable root parasite that can contribute to signifi cant genotype × parasite population interaction observed in field trials. The present study wa...

Four cycles of S1 family recurrent selection to improve grain yield and resistance to Striga hermonthica have been completed in TZE-Y Pop STR C0. In order to determine whether or not to continue with the recurrent scheme, it was desirable to evaluate the amount of residual genetic variance and as...

Cowpea is traditionally important as an affordable source of protein and minerals and of cash income in sub-Saharan Africa, especially for small-scale farmers who have limited options for food and cash crops. The development and deployment of cowpea varieties with improved nutrition and quality t...
