F2 populations of 47 crosses among 11 parental lines of Desmodium sandwicense bearing two major flower color classes, purple colored and near white flowers, were used to study the inheritance of flower color. The flower color was under monogenic control with a dominant colored gene, Ca, and a recessive white flowered gene, ca. Internode color ranging from dark red to green was under control of a different pair of genes, with a dominant gene for red, R, and a recessive gene for green stem, r. However. the two pairs of the genes were linked with an average recombination value of 34%. Silver markings on the midrib of the leaflet was controlled by a pair of genes with silver markings under a dominant gene, Ls, and a recessive non-marking gene, Is.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
