%X Representative data on genotypic differences in sorghum root characteristics are examined for prospective use in applied breeding programmes. Significant genotype differences in root characteristics observed are: root-length density at lower depths when the crop 15 grown

  on stored. soil moisture. root-shoot ratios  early establishment of nodal

  Roots In seedlings, and microbial associations of roots. Four-fold genotypic differences root-shoot ratio were found at the seedling stage, but

  high ontogenic shifts negated these differences at later stages. Hence

. sorghum breeding for efficient root systems should be confined to well-

  defined target environments with specific objectives.
