Overview
For decades, breeders have focused on traditional breeding to develop improved rice varieties. While this has brought significant advancements, it takes years before a variety is available for release. By then, farming conditions and market demands may have already been changed. In a rapidly evolving environment impacted by climate change, traditional breeding alone is no longer sufficient to meet the growing demand for improved rice varieties.
To address this, IRRI's Rice Breeding Innovations (RBI) has modernized its breeding strategy by incorporating cutting-edge technologies and tools. This approach enables breeders to enhance the genetic improvement rate of rice while reducing its breeding time. Key technologies and strategies include Rapid Generation Advancement (RGA) to accelerate rice variety development; Marker-Assisted Selection (MAS) and genomic selection to identify and incorporate desirable genes into the new rice variety; and gene editing to improve yield, disease resistance, and adaptability to tough conditions.
Beyond boosting productivity, RBI develops biofortified varieties to improve rice nutrition. Breeders apply genetic modifications that follow strict safety regulations throughout the process. Through this, RBI can enrich rice with essential nutrients like iron, zinc, and beta carotene which help combat issues relating to malnutrition.
As a result, smallholder farmers in vulnerable rice-growing areas will have access to improved rice varieties that increase their yields and income. Consumers and other end users, in turn, will also benefit from better nutrition, improved taste, and higher grain quality.
RBI Research Units
Product Development and Varietal Replacement (PDVR)
The breeding program develops high-yielding climate-resilient rice varieties for both transplanted and direct-seeded systems. It enhances stress tolerance and grain quality to increase market prices, benefit farmers and improve consumer quality.
Consumer-Driven Grain Quality and Nutrition Center
The Center conducts research to improve rice quality and nutrition, screening approximately 40,000 rice varieties annually. It focuses on key traits that influence texture, aroma, and nutrient content to develop rice varieties that meet consumer preferences and market demands.
Fit-for-Future Genetic Resources (FFGR)
This initiative conserves rice genetic diversity and germplasm to drive advancements in breeding. Managed under this initiative, the International Rice Genebank enables breeders to develop high yielding, climate-resilient, and nutrient-rich rice varieties.
Seed Health and Logistics Unit
(SHU)
This unit facilitates the safe and compliant exchange of seeds and biological materials for research. It manages genetic resource movement by conducting health testing, enforcing quarantine protocols, and upholding international standards.
Rice Genetic Design and Validation
This unit uses genome editing and transgenics to improve rice breeding efficiency. It supports the faster development of high-yielding, resilient, and nutrient-rich varieties through targeted regulatory processes, regional capacity-building, and strategic partnerships.
Breeding Analytics, Data Management, Software Development
This unit enhances breeding efficiency by leveraging advanced statistical analysis, robust data management, advanced data systems, and tailored software solutions. Specifically, it supports breeding programs through optimizing selection process, accelerating crop improvement, data driven decision-making and automating data analysis.

Dr. Sankalp Bhosale
Interim Research Director
Dr. Sankalp Bhosale is the Interim Research Director of IRRI’s Rice Breeding Innovations Department and leads the Product Development and Varietal Replacement Research Unit. He manages an extensive research portfolio and collaborates with over 50 CGIAR and NARES partners across Asia and Africa. His team enhances genetic gains and varietal replacement by advancing marker-assisted breeding, developing climate-resilient rice varieties, discovering stress-tolerance traits, and strengthening seed systems. Before IRRI, Dr. Bhosale was the Genetics Project Lead for Southeast Asia at Syngenta, Inc., and worked as a Molecular Breeder in Laos and Germany. He holds a PhD in Agricultural Sciences from the University of Hohenheim, focusing on plant breeding and population genetics, and a Master’s in Agricultural Sciences related to food security and resource management. Dr. Bhosale combines research and industry expertise to support global food security and improve farmers' livelihoods.
