Abstract:
Blast disease is the most damaging disease to rice which severely reduces its productivity. Traditional control systems are uneconomical at the business level. Utilizing resistant cultivars is the most efficient and sustainable strategy which is beneficial. Advancements in rice genomics have opened innumerable number of doors for the researchers to enhance the rice-productivity. As a viable procedure, Marker Assisted Backcross Breeding (MABB) is becoming more and more liked among researchers. Its key benefit is that it uses cultivars that farmers are already fond of, ensuring that the improved variety will possess the needed traits and also there is no any issue occurring in the method like transgenics. The potential to utilize this strategy with novel features in rice is made possible by the presence of widely cultivated popular varieties. Furthermore, the MABB method not only helps in early improvement of varieties but also essential for basic research applications in rice since it allows for far more precise production of novel varieties than traditional backcrossing. The revised data will be beneficial for the long-term, resistant rice breeding programme against the improved trait(s). Previous research on the current approach and challenges in disease improvement, such as the pyramiding resistance gene for creating new rice varieties with durable resistance, will undoubtedly aid in the fight against rice disease.
