In the vast agricultural fields of Uzbekistan, where cotton has been king for centuries, a quiet revolution is taking place. While the white gold has long been a cornerstone of the nation's economy, scientists are now looking beyond seasonal harvests to safeguard the very future of this vital crop.
Tucked away in research institutions across the country lies an extraordinary collection—not of artifacts or artworks, but of seeds. Uzbekistan's cotton germplasm collection represents one of the most comprehensive genetic libraries of cotton diversity in the world, preserving the evolutionary history and future potential of this crucial plant species 3 .
"Whether it's drought or disease, we can now act fast to find solutions"
This living library has become the frontline defense against modern agricultural challenges—climate change, pest resistance, and the narrowing genetic base of cultivated cotton. In this article, we explore how Uzbekistan is leveraging its rich botanical heritage to breed a more resilient future for global cotton production.
Uzbekistan's relationship with cotton runs deep. As the sixth largest cotton producer and second largest cotton exporter globally, the country produces 0.85-1.0 million metric tons of cotton fiber annually, valued at approximately $0.9-1.2 billion 3 .
Cotton occupies about 30% of all cultivated land in Uzbekistan, making it an undeniable cornerstone of the agricultural economy 3 .
Systematic collection and preservation of cotton genetic materials began through the efforts of Drs. N.I. Vavilov and F.M. Mauer 3 .
Dr. A. Abdullaev and his team dramatically expanded collections through scientific expeditions across Central Asia, Afghanistan, China, India, and beyond 3 .
7,500 accessions
Specializing in wild cotton species, primitive landraces, and domesticated genotypes from the entire Gossypium genus 3 .
12,000+ accessions
Maintains collections from 107 countries, particularly rich in cultivated varieties developed through worldwide breeding efforts 3 .
1,181 accessions
Focuses on specialized genetic stocks, including over 400 cytogenetic lines primarily derived from radio-mutagenesis experiments 3 .
| Type | Description | Approximate Count |
|---|---|---|
| Cultivated varieties | Domesticated cotton representing centuries of selective breeding | Over 25,000 accessions 3 |
| Wild relatives | Wild cotton species from across the globe | Nearly 2,000 accessions 3 |
| Genetic stocks | Specialized materials including monosomic lines, translocation stocks | Significant collections 3 |
| Interspecific hybrids | Artificially created hybrids combining traits from different species | Multiple experimental lines 3 |
Despite the tremendous diversity preserved in germplasm collections, modern cotton agriculture faces a critical problem: genetic uniformity. Commercially grown upland cotton (Gossypium hirsutum) accounts for approximately 95% of global production but suffers from a dangerously narrow genetic base 5 .
This limitation restricts the crop's ability to adapt to emerging pests, diseases, and changing climate conditions.
The vulnerability of genetically uniform crops is well-documented in agricultural history. When a population lacks genetic diversity, a single pest or pathogen can devastate entire regions of cultivation.
This is where germplasm collections become invaluable—they preserve the genetic variation needed to breed more resilient crops.
| Plant Material | Cotton Aphid Infestation (%) | Whitefly Infestation (%) |
|---|---|---|
| F1C Allotetraploid Hybrids | 5.2-5.6% | 5.4-5.8% |
| G. hirsutum cv. Ravnak-1 | 22.1% | 23.9% |
| Reagent/Material | Application |
|---|---|
| Colchicine (0.2% solution) | Induced polyploidy in sterile F1 hybrids to restore fertility 2 5 |
| SSR Markers | Verified hybridity and analyzed parental contributions 2 5 |
| Cytogenetic Staining Solutions | Enabled chromosome counts and meiotic studies 2 |
| Wild Gossypium Germplasm | Provided traits for pest resistance and stress tolerance 5 |
The scientific advances in cotton genetics are occurring alongside remarkable social transformation in Uzbekistan's cotton sector. For decades, the annual cotton harvest involved the mobilization of nearly two million adults and children, with forced labor comprising 15% of the cotton-picking workforce 4 .
Comprehensive reforms since 2017 have eliminated systemic forced labor and child labor, verified by the International Labor Organization in March 2022 4 .

Beginning of comprehensive reforms to eliminate systemic forced labor 4 .
International Labor Organization verification of elimination of systemic forced labor and child labor 4 .
Textile industry employed over 600,000 people, compared to 188,000 in 2018 4 .
The synergy between scientific innovation and social progress creates a powerful virtuous cycle: improved cotton varieties developed through germplasm research require fewer pesticide applications and are better adapted to local conditions, making cotton farming more sustainable and economically viable for independent farmers.
Uzbekistan's cotton germplasm collection represents far more than a historical archive—it is a dynamic resource for future agricultural resilience. As climate change accelerates and new crop diseases emerge, the genetic diversity preserved in these collections may hold the key to global food and fiber security.
The groundbreaking work on synthetic allotetraploids demonstrates how scientific ingenuity can bridge evolutionary gaps between species, creating new genetic combinations that nature alone might never produce. This research, coupled with Uzbekistan's remarkable social reforms in its cotton sector, paints a hopeful picture for the future of sustainable agriculture.
As Minister Abdurakhmonov's pioneering efforts show 1 , the answers to many of our future agricultural challenges may already exist—carefully preserved in seed form, waiting for scientists to unlock their potential. In the unassuming seeds of Uzbekistan's germplasm collection lies not just the history of cotton, but the blueprint for its future.
