Punjab Agricultural University Develops Game-Changing Virus-Resistant Cotton
In a significant leap forward for the agricultural sector, Punjab Agricultural University (PAU) in Ludhiana has successfully engineered virus-resistant breeding lines for cotton crops. These groundbreaking lines combat the devastating Cotton Leaf Curl Disease (CLCuD), offering a potential lifeline to cotton farmers in the region.
Leaf Curl Disease: A Persistent Threat to Cotton Cultivation
CLCuD, transmitted by the sap-sucking whitefly, has long plagued American cotton in North Indian states and neighboring countries, causing severe yield losses. The disease’s impact on farmers has been profound, with many forced to abandon cotton cultivation in favor of water-intensive paddy, further exacerbating the strain on Punjab’s dwindling groundwater resources.
PAU’s Two-Decade Long Endeavor Yields Results
The development of these resistant lines represents a major breakthrough achieved after over two decades of meticulous research by PAU’s dedicated cotton scientists. Dr. Satbir Singh Gosal, the Vice-Chancellor of PAU, emphasized the critical importance of managing leaf curl disease for the sustainability of cotton production, particularly in Asia.
Collaboration with ICAR-CICR for Commercial Release
The Indian Council of Agricultural Research’s Central Institute for Cotton Research (CICR) in Nagpur hailed PAU’s achievement as a remarkable example of pre-breeding. Dr. Y.G. Prasad, the Director of ICAR-CICR, affirmed their support in facilitating the commercial release of these virus-resistant lines after thorough multi-location trials. He further expressed optimism about the potential for developing varieties resistant to multiple pests, including the pink bollworm, based on these pre-breeding lines.
Unveiling the Science Behind the Resistance
Dr. Dharminder Pathak, principal cotton breeder at PAU, elaborated on the intricate process that led to this success. Leveraging the rich genetic diversity of wild cotton species, PAU initiated a wide-hybridization program 20 years ago to introduce CLCuD resistance genes into American cotton. This arduous endeavor, fraught with challenges, has culminated in the development of elite American cotton breeding lines exhibiting resistance to CLCuD, derived from the wild species Gossypium armourianum.
Significance and Future Implications
This groundbreaking research holds immense promise for the cotton industry, not only in India but globally. By providing farmers with CLCuD-resistant cotton varieties, it has the potential to revitalize cotton cultivation, enhance yields, and improve the livelihoods of millions of farmers. Moreover, this development could pave the way for further advancements in cotton breeding, including the development of varieties resistant to other devastating pests like the pink bollworm.
Summary
Punjab Agricultural University has made a significant breakthrough in cotton cultivation by developing virus-resistant breeding lines against Cotton Leaf Curl Disease. This achievement, realized after two decades of research, offers hope for revitalizing cotton production and mitigating the economic losses incurred by farmers due to the disease. The collaboration with ICAR-CICR aims to accelerate the commercial release of these lines, further strengthening the resilience of the cotton industry.
