dc.description.abstractSorghum bicolor (L.) Moench (2n=20) is the most important drought tolerant cereal crop and is the crop of choice in semi arid tropics. After soil nutrient deficiencies, drought stress is the major constraint limiting the sorghum production. Drought that effects during post flowering stage is often referred as terminal drought. The trait associated with terminal drought tolerance is stay green, which is complex and difficult to score with normal breeding approaches. Using MAS in breeding programs it is possible to introgress drought tolerant QTLs (stg1, stg2, stg3, stg4, stgA, and stgB) from the donor parent (B35) into the genetic backgrounds of elite parents like S35, ICSV 111, and IRAT 204. The homozygous QTL introgression lines in the background of S35 and ICSV 111 were generated as a part of the present investigation by using MAB. Based on marker data obtained the seeds of self-selected plants are send to Ghana for initial phenotypic evaluation trails. In addition, the selected backcross progenies of the recurrent parent IRAT 204 were advanced to BC3F1 and BC4F1 generations. Sorghum is the logical complement of other important cereal crops and has made unique contributions in understanding the genetic basis of cereal domestication. The sequencing of sorghum will definitely help the plant breeders and molecular biologists in tracking out the unknown agronomically important genes or QTLs.en_US
