Phytotoxins: The Cause of Virulence in Ascochyta rabiei

I. A. Khan, J. A. Khan and S. S. Alam

Abstract

Isolates of Ascochyta rabiei were collected from different chickpea growing areas of Pakistan. The isolates were tested for virulence on two chickpea cultivars ILC-3297 (resistent) and ILC-1929 (susceptible). These isolates were found to synthesize different amounts of phytotoxins Solanapyrone A and C. The virulence of the isolates were found dependent upon the amounts of phytotoxins produced by these isolates.
