Genetic analysis of agronomic characters in chickpea using line × tester mating design

Twenty-one crosses developed from the frame of line × tester analysis along with ten parents were grown in two replicates experiment. Data on days to flowering, days to maturity, plant height, number of pods/plant, number of primary branches, number of secondary branches, number of tertiary branches, number of seeds per pod and seed yield per plant (g), revealed high significant differences exist among lines,...

Inheritance of bacterial wilt resistance in five tomato cultivars

Five tomato cultivars were studied for inheritance of bacterial wilt resistance. Lines AVTO1429, AVTO1424, and AVTO1314 have the resistance gene, Roma VF lacks the resistance gene, and Valoria Select is claimed to have resistance but has not been evaluated. The study, which was carried out in a split plot design, involved six generations and backcrosses that were conducted in a greenhouse and a field. Artificial...

Diversity of Dioscorea bulbifera Linn in Uganda assessed by morphological markers and genotyping-by-sequencing technology (GBS)

Dioscorea bulbifera L. is a widely distributed plant in the humid and sub-humid tropics. The taxonomic treatment of this species is ambiguous due to its extreme polymorphic morphological characters. Therefore, it is imperative to assess the species distribution, and the inter and intraspecific variability relationships in D. bulbifera. In this study, the genetic diversity and species distribution of 41 accessions of D....
