Abstract

Bacterial leaf blight of rice, the second most devastating disease of rice causes substantial yield loss. Study of pathogenic variability and identification of resistance genes are key factors in breeding against this disease. Bacterial leaf blight is now a serious constraint for rice production in the irrigated and low land ecologies in all rice growing countries. 223 lines (landraces) were collected from different regions of Bihar and Jharkhand and were screened against bacterial blight. Out of 223 lines, eight lines, namely Bhathani, Hardi Muri, Sitwa dhan, Jhulat, Lambasari, Karijiri, Swarna gora and Sita gora were found to be highly resistant.
