Potential in a collection of adapted and exotic tropical maize inbred lines as resistance source for stem borers
Lepidopteran borers are the most devastating field pests of maize in West and Central Africa. In view of the rapidly changing climate which favours an upsurge of more destructive biotypes of insect pests, diverse sources of resistance from different genetic backgrounds need to be harnessed for crop improvement purposes. Forty tropical maize inbreds comprising adapted and exotic lines from International Institute of...

Agro-morphological characterization of some taro (Colocasia esculenta (L.) Schott.) germplasms in Ghana
Taro (Colocasia esculenta (L) Schott.) is one of the underutilized crops in Ghana which has great potential in terms of food and nutritional value. Eighteen (18) accessions collected from Samoa (8), Malaysia (2), Indonesia (2) and Ghana (6) were studied under field conditions to collect data on their agro-morphological characteristics and yield potential for the development of the crop. The study was conducted at...

Varietal screening for resistance against field and storage crop pests: An implication for Ethiopian crop variety development
Food security in developing countries like Ethiopia has been a challenge for many years due to pre and post-harvest losses of agricultural products which are caused by different biotic and abiotic factors. Grain losses from pest infestation prior to harvest and during storage are a serious problem, particularly in developing countries like Ethiopia. More than 70% insect pests have been identified; they attack...

Evaluation of constraints in production of root and tuber crops in Ethiopia: Overview of policy neglected climate resilient food security crops
The objective of the current study was to examine the major constraints in production of root and tuber crops in Ethiopia with emphasis on identifying the policy gaps. This appraisal was based on survey report of Central Statistical Agency (CSA) for the period of 2011 to 2015. Data of CSA report was chosen for the current study with the view to gain an overview of policy packages in root crops in contrast with other...
