The relation between certain host characters and bacterial blight incidence in rice

Abstract

Amongst the different morphological features of rice varieties studied, no correlation was obtained between disease development and narrow or broad leaves, thick and thin leaves, pale and dark green leaves. However a strong correlation was observed between hairy and glabrous leaf texture and disease development. Hairy varieties suffered significantly more disease than glabrous varieties under natural field conditions though both were equally susceptible when pin-prick inoculated with the pathogen.
