Genetic basis of shoot branching in sorghum at University of Queensland, Australia
Embedded Files
Tillering in sorghum is an important trait influence sorghum yield under drought and heat stressed environments. The main aim of the project is to understand the differences in tillering in sorghum and predict tillering under diverse genotype x enviornment x management (GxExM) scenarios. The project was funded by Australian Research Council to form a centre (https://www.plantsuccess.org/).
We used several approaches, not limited to assembling the largest collection of diverse sorghum lines, genome wide association mapping (GWAS), nested association mapping (NAM), development of mapping populations, selection mapping, pan-genome analysis, and comparative genomics to identify genes networks for tillering in sorghum.
Wheat Physiological Pre-breeding and Genetics at Global Wheat Program, CIMMYT, Mexico
Developed spring wheat pre-breeding lines for improved yield potential, drought and heat stress tolerance at the International Maize and Wheat Improvement Center (CIMMYT), Mexico through physiological pre-breeding. The germplasm -including synthetics and landraces- from largest wheat gene bank in the world was screened for several traits such as agronomic and physiological traits. The lines were crossed to elite lines- wide adapted and disease resistant- and advaned to several generations before delivering to national breeders in several countries that were used as parental lines in the wheat breeding programs as well as direct releases. During 2015 to 2021, more than 300 lines were distributed to 100 countries in the Global South, which are still being used as parents in breeding programs and release as varieties.
