Intraspecific variabilities in 40 accessions of African yam bean (AYB) were assessed through characterization of 48 agromorphological traits for two cropping seasons between June and December 2011 and 2012. Data were analyzed using descriptive statistics, analysis of variance (ANOVA), correlation analysis, principal component analysis, and cluster analysis (Semi - partial R squared method). The accessions showed significant differences (P ≤ 0.05, P ≤ 0.01, P ≤ 0.0001) in 16 reproductive traits. Accessions TSs 66 (144.50 days), TSs 51 (144.67 days) and TSs 154 (144.67 days) were identified as early maturing accessions. The first five principal component axes explained 69.7% of the total variation with PC1 and PC2 contributing 38.9% to the total variation. Correlation coefficients were high and significant for yield traits. A highly significant correlation (r = 0.99***) was observed between seed yield (kg ha-1) and weight of total pods per plant. Tubers were produced from 42.5% of the accessions. The accessions of AYB were meaningfully grouped into five clusters at the R-squared distance of 0.04 similarity index. Phenotypically, AYB 57 and TSs 123 were the most similar accessions with the closest distance of 0.0071. Four seed shapes were identified; oval (82.5%), globular/round (5%), oblong (10%), and rhomboid (2.5%). In order to improve the yield of AYB, the number of seeds per pod, number of pods per plant, weight of total seeds per pod, and weight of total seed per plant are important determinant factors. The genetic variabilities observed in the traits studied could be utilised for improvement of AYB.
MAPPING THE EFFECT OF FOOD PRICES, PRODUCTIVITY AND POVERTY IN THE DEVELOPMENT DOMAINS OF NIGERIA

Poverty remains the major obstacle to economic emancipation and achievement of development agenda in Nigeria. Worse still, rising food prices pose a major threat to feeding the teeming population in Nigeria. Declining food production, high population growth, and negative food trade balance combine to worsen the food and poverty situations in Nigeria. We stand on the premise that surging and volatile food prices could have a hardest hit on those who could not afford it – the poor. This study used spatial data on food prices and poverty levels. We mapped food prices and poverty levels by development domains in Nigeria. We found that food price has significant effect on poverty levels in the identified development domains. The food price analysis showed high and rising food prices with high food price instability and price spread. The high food price had effect on purchasing power and poverty levels of Nigerians. The food price surge also had a direct impact on overall inflation because the weight of food in the consumption basket is high. Food inflation ranges over 60 percent, and food inflation has reached double digits. The poverty change analysis revealed that some States witnessed improvement in poverty reduction, while others had their poverty situation worsened. The GIS mapping and overlay of food prices and poverty levels by development domains showed critical policy intervention areas in Nigeria. Policy recommendations that are consistent with food price stabilization and poverty reduction strategies were canvassed. There is need for more effective policy to help the poor and farmers to respond to the opportunity posed by the rising demand for food.
