Combining ability for yield and yield components in six parents and their 15 F1 hybrids of sesame (Sesamum indicum L.) in half diallel mating design
Combining ability estimates were studied for seed yield, yield components and other morphological traits in six sesame parental lines and their 15 F1 hybrids crossed in half diallel for two consecutive seasons 2012/2013 - 2013/2014 at Gadaref University Farm, Gadaref, Sudan. Combining ability analysis revealed that both additive and non additive types of gene actions were important in the studied traits. For days...
Genetic diversity and adaptation to different tillage and farming systems of cocoyam genotypes (Xanthosoma sagittifolium L. Schott) in the Eastern Region of Ghana
Experiments conducted in Ghana show that cocoyam exists as mixtures of clones in farmers farms. This work aimed to use RAPD markers to determine the extent of diversity in cocoyam genotypes collected from farms at different locations in the Eastern region of Ghana. The study also investigated whether the genotypes have different adaptation to different farming systems (intercropping with plantain and sole cropping) and...
Genetic diversity in Tepary bean (Phaseolus acutifolius) landraces grown in Botswana
A field experiment was conducted at Department of Agricultural Research in Sebele in the 2012 to 2013 season using nine accessions that were sourced from the National Plant Genetic Resource Centre (NPGRC), Gaborone, Botswana. Multivariate statistical procedures such as clusters and principal component analysis were used on 15 selected characters to assess agro-morphological variability among tepary bean landraces...
