Article Synopsis
- Crop wild relatives, like Gossypium anomalum, hold crucial genetic diversity for improving agricultural species, but their integration into breeding faces challenges due to reproduction barriers and limited genomic data.
- A new genome for G. anomalum was created, allowing for the development of 74 chromosome segment substitution lines (CSSLs) that incorporate wild genetic material into Gossypium hirsutum cotton cultivars, which included traits for plant height, yield, and fiber quality.
- The study successfully identified two valuable genes related to drought tolerance and fiber strength from G. anomalum, showcasing the potential of using high-quality wild genomes to enhance crop breeding programs.
We reported the first development of Gossypium anomalum -derived microsatellite markers and identification of recombination between sexually incompatible species by a synthesized hexaploid on genome level. To continue to develop improved cotton varieties, it is essential to transfer desired characters from diploid wild cotton species such as Gossypium anomalum to cultivated allotetraploid cotton species. However, interspecific reproductive barriers limit gene transfer between species.
