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...

Abstract. Salinity constraints for Rice cultivation in Camargue mainly concern short periods (5-10 days) during the first cropping month (from germination to 5th leaf stages). Because of unfavourable climatic conditions, it is impossible to directly undertake breeding lines field screening. So greenhouse tests have been performed in order to specifically screen for varietal salt tolerance accor...

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...

Identification of the seed varieties is essential in quality control and high yield crop growth. The existing methods varietal identification rely primarily on visual examination DNA fingerprinting. Although pattern fingerprinting allows precise classification but fraught with challenges such as low rate polymorphism amongst closely related species, destructive method analysis a huge cost invol...

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...

The 'Plantain-Optim' dataset (came from the 'Plantain-Optim' experiment conducted from 2009 to 2011 at CARBAP experimental station in Cameroon. The main objective was to describe agronomic potential of nine plantain varieties, including five natural plantains commonly cropped in Cameroon, and four plantain-like hybrids. A completely randomized bloc permitted to compare growth, development and y...

Production and area of chickpea are reducing every year in India due tocompetition with horticulture and other cash crops in irrigated areas. There is a greatscope for expanding chickpea production with or without limited irrigation in rainfedrice fallow lands (RRFL) in the states of Chhattisgarh and Madhya Pradesh. Nineteenchickpea genotypes were tested using participatory varietal selection (...

The status and rank of mosquito varietal names listed in A Catalog of the Mosquitoes of the World are reviewed. Names proposed or adopted for existent varieties are deemed to be subspecific or infrasubspecific under provisions of the International Code of Zoological Nomenclature that regulate the rank of species-group names that follow binomina. Type data and taxonomic information are provided ...

Resistance to a number of nematodes is present in varieties of temperate and tropical cereals. The occurrence, nature, and inheritance of varietal resistance in cereals is reviewed. Evaluation of the practical significance of nematode resistance in a particular host-nematode combination is discussed in relation to host efficiency, host sensitivity, genetic control of resistance, and presence of...
