In the semi-arid tropics of Asia and Africa, conditions can be difficult for crops. Plants need to have short growing seasons, survive on poor soils and tolerate environmental stresses. Enter, the millets.

The plant source materials were obtained from the International Crops Research Institute for the Semi-Arid Tropics in India. The researchers’ goal was to better understand the genetic diversity within and between each variety of millet They uncovered tiny differences in the DNA sequences of the various plants. These genetic differences may ultimately be connected to characteristics, such as drought tolerance and growth rate. By collating field results and genetic data, researchers identify desired traits and develop improved varieties. An important part of breeding desirable varieties of a crop is understanding how existing ones are related to each other. Uncovering the underlying genetics, as in this study, can help plant breeders develop millet varieties with desired physical characteristics
