This study employed the quadratic classification function analysis to examine the influence of farmer's socio-demographic and varietal characteristics of maize on adoption of improved maize varieties (IMVs) in the Wa Municipality of the Upper West region of Ghana. The results showed that, farm labour, information availability about the variety, weed resistance, low yielding variety, early matur...

Varietal purity and proportions of grains with brown spots, fissured grains, chalky grains andwhole grains in a rice sample are important grain quality attributes influencing consumers'preference and price but little information exist on how these grain quality attributes are affectedby biophysical factors and pre-harvest practices. Several authors have studied in isolation theeffect of biophys...

Large-scale yield trials have traditionally been used to rate the reactions of released sugarcane varieties to ratoon stunting disease (RSD). These trials are time-consuming and require large tracts of land and are therefore not suitable for incorporation into a routine programme of disease screening of new genotypes. Using a tissue blot-enzyme immunoassay (TBIA) to determine the percentage of ...

Grapevine (Vitis vinifera L.) is one of the world's most important crop plants, which is of large economic value for fruit and wine production. There is much interest in identifying genomic variations and their functional effects on inter-varietal, phenotypic differences. Using an approach developed for the analysis of human and mammalian genomes, which combines high-throughput sequencing, arra...

The basic diversity data of landraces has been found important to monitor the dynamics of crop genetic resource management. The diversity data generated in time and space have been valuable to communtities, scientists and policy managers to formulate and implement conservation strategies of in situ, on-farm as well as ex situ conservation and management of genetic resources. In this paper, we d...

Bacterial wilt caused by R. solanacearum is a constraint that limits the production of solanaceous in Côte d'Ivoire. The genetic control, which more widely used, comes up against and phenotypic variability strains. objective this study was to screen commercial traditional varieties Solanaceae Ivorian strains different phylotypes assess their spectrum resistance disease. level virulence five eva...

The predicted world population increase along with climate changes threatens sustainable agricultural supply in the coming decades. It is therefore vital to understand crops diversity associated to abiotic stress response. Heat stress is considered one of the major constrains on crops productivity thus it is essential to develop new approaches for a precocious and rigorous evaluation of varieta...

This paper presents a participatory modeling for multi-points of view description of a system from scientists’ knowledge. The method is applied in the development of a generic model for agro-biodiversity dynamics in developing countries with a focus on crop genetics diversities evolution through the stakeholders’ management at different scales. The model description is based on the knowledge of...

A rapid screening (hydroponic) and field testing programme There is increasing interest in improving the nitrogen (N) use efficiency of cultivated crops, due to the high cost of synthetic N fertiliser. Since existing differences in N use efficiency between sugarcane varieties could be exploited to improve N fertilisation, a hydroponic pot experiment was conducted to test the performance of seve...
