Abstract

Rapid increase in human population and reduction in arable land due to urbanization and other soil problems, the demand for promoting cotton yield is increasing continuously. The major limiting factors for increasing yield are biotic and abiotic stresses, global climate change, genotype x environment interactions, limited germplasm resources, and negative association between yield and fiber quality. To meet the demands of rainfed cotton growers of Central Zone of India, concentrated breeding efforts at Cotton Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola resulted in development and release of high yielding variety Suvarna Shubhra (AKH-09-5) having medium duration and desirable fibre properties. It was continuously evaluated in University Trials, State Multi Location Trials and All India Coordinated Research Project on Cotton (AICRP) trials from 2011-12 to 2018-19 before its release. It was tested on farmer’s field through adaptive trials also. This variety has recorded higher yield compared to the check varieties in all the trials. It is tolerant to leaf hoppers and important cotton diseases. In addition, it has good fibre qualities and acceptable boll size. Due to these desirable features, farmers have shown acceptability to this variety in adaptive trials and because of high lint yield potential and good fibre qualities, ginning industry and mill owners can satisfy their demands.

Conclusion

Concentrated breeding efforts at Cotton Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola resulted in development of American cotton variety Suvarna Shubhra (AKH-09-5). It has been tested continuously over seven years in different University, State and AICRP on Cotton trials and found promising for seed cotton yield, lint yield, fibre qualities and pest and disease tolerance. It has shown promising performance on farmer’s field in adoptive trials also. Considering its performance, it has been released and notified for Central Zone States of India including Maharashtra, Madhya Pradesh, Gujarat, South Rajasthan and Odisha for rainfed cultivation.
