appropriate collections from dissimilar climates and recombining them into more widely adapted improved types useful to the world's people.

The profuse branching and wide distribution of the root system is one of the main reasons why the sorghums are so markedly drought resistant. Other factors are however of importance. In the first place the plant above ground grows slowly until the root system is well established. Secondly, the system has to supply a leaf area which is approximately half the leaf area of maize. Thirdly, the low transpiration rate must influence the water demands. Finally, the plant can remain dormant during a prolonged drought and thereafter recontinue its development.
