Identifi cation of Landraces of Rice from Jharkhand and Bihar Resistant to Bacterial Blight

Abstract

Bacterial leaf blight of rice, the second most devastating disease of rice causes substantial yield loss. Study of
pathogenic variability and identifi cation 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.
