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. 1990 Conference or Workshop Item PeerReviewed application/pdf en http://oar.icrisat.org/3649/1/Proceed._of_Nat._Conf._of_Plant_Physiology_Assessemnt_of_genotype_NS_DJF_RJ_KRK_JMP_SS%2CPS_AVR_SPW_1988.pdf Seetharama, N and Flower, D J and Jayachandran, R and Krishna, K R and Peacock, J M and Singh, S and Soman, P and Rani, A U and Wani, S P (1990) Assessment of Genotypic Differences in Sorghum Root Characteristics.
