Soybean rust, caused by Phakopsora pachyrhizi, is an important disease in Nigeria and many other soybean-producing countries world-wide. To determine the geographical distribution of soybean rust in Nigeria, soybean fields were surveyed in the Derived Savanna (...
Gondal and extragonadal sperm reserves were determined in testicular and epididymis tissues obtained from Boran and Boran X Friesian bulls fed either a high or low plane of nutrition diet for a one-year period. The bulls were 32 months of age at castration. Mean body weights did not differ betwee...
A selection programme was set up in 1983 in the Ivory Coast to improve the growth and live weight of the indigenous Djallonke sheep using an open nucleus breeding system. Selection was based on male individual weights at 80, 180 and 365 days of age. Multiple sires were used in farmers' flocks. In...
Review on the analytical and biological testing of opaque-2 modified colombian corn hybrids in presented. The discovery of flint kernels in segregating ears opens the possibility of developing high lysine varieties with different characteristics which would increase the acceptability of modified ...
Cowpea is an important food legume and versatile crop in the savannas of northeast Nigeria. Despite the high potential for production in this region, insect pests are a major constraint. A study was conducted to evaluate the response of diverse cowpea genotypes to different schedules of spraying ...
Cassava, a staple food in sub-Saharan Africa, does not provide adequate amounts of pro-vitamin A (VA) carotenoids and has been targeted for biofortification (i.e. selectively breeding cultivars of increased nutrient density with agroeconomically acceptable characteristics). However, the accessibi...
Objective: Drought and low soil nitrogen(low N) are the most important environmental constraints contributing to yield in stability of maize (Zea mays L.). Evaluation of maize genotypes under different stresses would be useful for identifying genotypes that combine stability with high yield pote...
Nine cassava genotypes were evaluated for their growth responses and adaptability to soil moisture stress on the field and in the screen house in Nigeria. Genotypes were evaluated in three savanna agroecologies in a randomized complete block design with three replicates. Screen house evaluation w...
Thirty-six inbred lines selected in West and Central Africa for moderate to high resistance to maize ear rot under conditions of severe natural infection were screened for resistance to aflatoxin contamination using the previously established kernel screening assay. Results showed that more than ...
