Interpretive Summary:

Technical Abstract: Induced mutagenesis is a powerful approach to generate variations for elucidation of gene function and create new traits for breeding. We have developed a pedigreed mutant library through chemical mutagenesis with ethylmethane sulfonate (EMS) treated seeds in sorghum, sequenced 256 randomly selected lines, and developed fast forward genetic pipeline to efficiently identify causal mutations for traits of interest. The mutant library displayed many traits of significant agronomic value. Fast causal gene discovery from mutant libraries combined with efficient genome editing techniques will accelerate incorporation of new traits and revolutionize crop breeding.
