Towards a reliable method to select potentially high value Erianthus hybrids* [Full subscriber]

A key component of the sugarcane breeding program is introgression of new characteristics from wild species. Erianthus, a closely related genus to sugarcane, is a good candidate as it contains a number of traits of agronomic importance including pest and disease resistance and tolerance to drought and water-logging conditions. Fertile hybrids from intergeneric crosses between Saccharum officinarum and E. arundinaceus have been produced and studied. The chromosome composition of these hybrids was examined through the back-crossed generations and this revealed a loss of Erianthus chromosomes as well as recombinant chromosomes from both genera. There is potential that these recombinant chromosomes…
