Abstract

Seeds of corn inbred lines collected at the National Corn and Sorghum Research Center (NCSRC), Kasetsart University,
were analyzed to determine the contents of phytic acid (PA) and inorganic phosphorous (InP). These 28 and 29 inbred lines
were cultivated at the NCSRC (in the 2008 late rainy season and 2009 early rainy season) to evaluate their resistance to corn
downy mildew caused by Peronosclerospora sorghi. Results showed that the values of the PA, InP contents and downy
mildew infection were statistically different among these inbred lines in both seasons. However, there were no correlations
between the contents of either PA or InP and downy mildew infection.
