Development of a haploid induction system for cotton
Anchoring and characterizing variation in the cotton genome
In an effort to fully leverage cotton genomics for plant breeding, the SBC coordinated partnerships with David Stelly (Texas A & M) and BGI. The genomes of 11 G. hirsutum lines (Upland) and one G. barbadense (Pima) line were sequenced to define DNA diversity in breeding materials. Unlike the limited diversity found in the genome (as revealed in transcriptomes), a wealth of DNA changes was detected in the non-coding regions. Led by Amanda Hulse (in Stelly’s group) and Hamid Ashrafi (UC Davis), a DNA Illumina array containing 70,000 markers was created and made available for breeders to analyze their germplasm. This collaboration included public and private institutions from Australia, India, France and United States. This work was funded by Cotton Incorporated.
