Characterisation of genetic diversity among Sudanese sorghum accessions using molecular markers and phenotypic characteristics

Abstract: 
Sorghum is an important staple food grain crop for the millions of people living in the semi-arid tropics in Asia, Africa and Latin America. The present study examined phenotypic and genotypic characteristics of 95 Sudanese sorghum accessions. Morphological and molecular markers were employed to study the genetic variability among the accessions. A total of 10 morphological markers and 15 simple sequence repeats (SSRs) primers were used. Cluster analysis based on morphological traits revealed thirteen distinct clusters basis on their morphological characters with two accessions forming independent cluster. Based on molecular markers, twelve distinct clusters were observed.
Le sorgho est une céréale importante utilisée comme aliment de base pour des millions de personnes vivant dans les tropiques semi-arides d’Asie, d’Afrique et d’Amérique latine. La présente étude a examiné les caractéristiques phénotypiques et génotypiques de 95 accessions de sorgho soudanais. Les marqueurs morphologiques et moléculaires ont été utilisés pour étudier la variabilité génétique parmi les accessions. Un total de 10 marqueurs morphologiques et de 15 premiers éléments des répétitions de séquences simples (SSRs) a été utilisé. Une analyse de groupement basée sur les caractères morphologiques a révélé treize groupes distincts sur la base de leurs caractères morphologiques avec deux accessions formant un groupe indépendant. Sur la base de marqueurs moléculaires, douze groupes distincts ont été observés.

"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme plant breeding".
