This study focuses on the genetic diversity and population structure of coffee germplasm in China. Using advanced techniques like RAD-seq, researchers analyzed a collection of 185 coffee varieties and wild relatives. The goal was to understand and preserve the genetic resources crucial for coffee breeding and conservation.
• The coffee germplasm collection captured 98% of known disease-resistance genes, ensuring high genetic diversity.
• Population structure analysis identified three distinct groups, with one group showing the most genetic variation and complete disease resistance coverage.
• The study found 47 selective sweep regions linked to coffee's domestication and adaptation, highlighting the importance of genetic diversity.
• This research aligns closely with global coffee genetic resources, confirming the collection's representativeness.
Understanding coffee's genetic makeup is vital for developing resilient varieties that can withstand climate change. This work supports sustainable coffee production and conservation efforts, ensuring the future of this essential crop.
