Farmer’s management practices to maintain the genetic diversity of sorghum (Sorghum bicolor L. moench) in south of Chad
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2016, Vol 4, Issue 0
Abstract
The objective of this study was to understand the farmer management practices in order to conserve the genetic diversity of sorghum and to determine the level of genetic diversity and local taxonomy in two regions (Logone Oriental and Moyen Chari) of the South of Chad. Total eight villages were visited and from these 53 accessions were collected from 116 inventoried accessions. The number of collected accessions varies from 3 to 9 per village and a loss of diversity was reported between 47 to 71% (average rate of 54.31%) in all villages and this rate varies from village to village. Results of study revealed that the farmer nomenclature is based on the criteria of accession using, origin, color of seeds, type of panicle, crop cycle and the size of plants. This study suggested significant losses in the sorghum diversity of Chad. Therefore, there is a strong need to run a national program to collect, validate and protect the genetic resources of sorghum. This will be helpful in the reducing genetic erosion and to improve the varieties of sorghum cultivated in Chad.
