Maize (Zea mays L.) is an important food crop in the Guinea savannas of Nigeria. Despite its high production potential, drought, Striga hermonthica parasitsim, and poor soil fertility particularly nitrogen deficiency limit maize production in the savannas. Breeders at IITA have developed drought-...

The East African highland banana (Musa spp. AAA) is an economically important food crop. The crop is affected by a number of diseases and pests. Genetic improvement of the crop is hindered by very low seed set and poor seed germination. The objective of this study was to compare seed set, seed qu...

Assessment of the existing PCR-gel electrophoresis-based methods for detection of Rx1 and Rx2, the genes that independently control extreme resistance (ER) to Potato virus X (PVX), indicated that the 5Rx1F/5Rx1R primer pair led to reliable detection of Rx1 whereas the 106Rx2F/106Rx2R primer pair ...

Plantain is one of the most important sources of food in the African lowlands stretching from the lowlands of Guinea and Liberia to the central basin of the Democratic Republic of Congo (DR Congo). Because plantain cultivars do not produce seeds, plantain cultivation is based on vegetatively tran...

This work focused on the morphological characterization of plantain cultivars collected in the period 2005–2014 in 280 villages across 9 provinces of the Democratic Republic of Congo. These cultivars were established in two field collections at the University of Kisangani.Existing descriptors wer...

The goal of this research was to evaluate diverse cowpea genotypes developed over the past 4 decades in the Nigerian Sudan Savannas for their agronomic performance and to identify groups of cultivars with similar quantitative characters. Characterization would facilitate the efficient synthesis o...

Black leaf streak (BLS), an airborne fungal Black leaf streak, caused byMycosphaerella fijiensisMorelet, is a major constraint to plantain production. Owing to limitations associated with the use of chemicals in Africa, development of resistant cultivars seems to be an appropriate approach to con...

Accurate assessments of genetic gains ensuing from plant breeding for the most important agronomic characteristics in Nordic spring barley (Hordeum vulgare L.) are not available. Hence this research was aimed to determine the rate of genetic improvement in the Nordic barley breeding pool. This st...
