In Mushie ranch, 157 N`Dama progeny of four sires, 95 males and 62 females, were used to estimate the habitability levels for aspects of parasitaemia, anemia control, immune response and animal performance. The males were exposed to a high natural trypanosome challenge, and body weight, trypanoso...
Multiple co-infections by different pathogens on common bean (Phaseolus vulgaris L.) affect its productivity and cause complete crop loss in susceptible varieties. Therefore, gene pyramiding using marker assisted selection (MAS) and backcrossing, provide alternative cost-effective control measu...

The agronomic potential of landraces and cultivars must be determined for an optimal utilization of genetic resources in Musa improvement. Field assessment of 75 plantain landraces and 17 banana cultivars was carried out in two representative locations in Nigeria: Onne (southeastern humid lowland...

Resistance and resilience to naturally acquired gastro-intestinal (GI) nematode parasite infections (predominantly Haemonchus contortus) were studied in 1785 lambs born over six lambings (1991 to 1996) consisting of 212 Red Maasai, 311 Dorper and 1262 crossbred (Red Maasai-Dorper) lambs in the su...

This article attempts to evaluate the current state of knowledge on questions such as, to what extent is inheritance important and how is it influenced by environmental factors; what are the mechanisms underlying increased resistance; and how productive are these breeds under various levels of ch...
Breeders should maintain sufficient genetic variability in a population to ensure continuous advance from selection for a target trait. The extra-early-maturing Striga resistant/tolerant maize (Zea mays L.) populations, TZEE-W Pop DT STR (white) and TZEE-Y STR (yellow), have each gone through thr...

The metric measures on seeds, their correlation and relationship are important for systematic breeding for seed yield and shape determination. Variations among eighty genotypes of African yam bean (AYB) for six metric seed characters (seed length, width and thickness and their ratios) were evalua...
The Menz and Horro highland sheep breeds are being evaluated at the ILCA Debre Birhan research station in Ethiopia for between-and within-breed genetic variation for resistance to internal parasites. The experimental design involve mating, for each breed, 150 ewes with 10 rams to lamb at the begi...

A preliminary trial was conducted to determine if there were variabilities in seedling morphology of selected cowpea varieties and determine their heritability with aim that this could be used in future cowpea breeding for selection at seedling stage. The characters studied include hypocotyl, epi...
