Title Fine Mapping of Shoot Fly Resistance and Stay-Green QTLS on Sorghum Chromosome SBI-10

Description Sorghum [Sorghum bicolor (L.) Moench, 2n = 2x = 20] is the fifth most
important cereal crop globally, and is grown primarily in arid and semi-arid
conditions. Major biotic and abiotic constraints hampering sorghum production
include shoot fly infestation during early stages of crop development (seedling
establishment and early growth stages; but only present in the eastern
hemisphere) and terminal drought stress during post-flowering growth stages.
These two stresses can devastate the crop. Hence developing sorghum varieties
with resistance for these two stresses is critical. In order to understand the
genetic basis of sensitivity to these two stresses and to genetically dissect host
plant resistance to shoot fly and tolerance to terminal drought stress, the
following objectives were proposed for the present study:
 to develop an introgression-line cross-based fine-mapping population for
morphological components of shoot fly resistance and for the stay-green
mechanism of terminal drought tolerance previously mapped to sorghum
chromosome SBI-10L;
 to fine-map the target traits by combining genotyping and phenotyping
datasets of a selected recombinant sub-set of the fine-mapping population;
 to annotate functionally and characterize candidate genes identified in the
target region; and
 to identify recombinant progenies with pyramided traits of interest.
