Genetic variability of soybean for yield and yield components under irrigation conditions of Gezira, Sudan

Abstract: 
A field experiment was conducted to study the genetic variability among 21 soybean verities at the Gezira Research Station Farm, Sudan for two successive seasons in 2009 and 2010. Six traits were studied including grain yield/ha, days to 50 flowering, days to maturity, plant height, height to first pod and number of pods/ plant. Individual analysis of variance revealed highly significant differences among the 21 genotypes in all studied traits. Grain yield ranged from 2709-1200 kg/ha. The heritability (h2) estimates ranged from 43% to 85%. The highest estimates were given by days to maturity and plant height.
Une expérience de terrain a été menée pour étudier la variabilité génétique parmi les 21 vérités de soja à la ferme de Gezira (Gezira Research Station Farm) Station de recherche, au Soudan pendant deux saisons successives en 2009 et 2010. Six caractéristiques ont été étudiées, y compris le rendement en grains / ha, les jours à 50 floraisons, les jours jusqu’à la maturité, la hauteur des plantes, la hauteur de la première gousse et le nombre de gousses par plante. L’analyse individuelle de variance a révélé des différences très significatives entre les 21 génotypes de tous les caractères étudiés. Le rendement en grain allant de 2709-1200 kg / ha. Les estimations de l’héritabilité (H2) vont de 43% à 85%. Les estimations les plus élevées ont été données par la précocité et la hauteur des plantes.

About the RUFORUM 2010 Biennal Conference
"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 stakeholders 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 of Plant Breeding"
