   Subscribe/Renew Journal


The paper deals with field resistance of different hard pines being raised in plantations in India against Cercoseptoria needle blight disease. Based on field observations, Pinus radiata, P. roxburghii. P. oocarpa and P. caribaea var. bahamensis are categorized as susceptible to the disease. P. caribaea var. caribaea, P. greggii, P. pseudostrobus and P. patula are categorized as moderately resistant in plantations which are raised out side their natural temperature zones but resistant in plantations raised in their natural temperature zones. P. kesiya, P. elliottii and P. c1ausa are found resistant to the disease.
