  Six rice mutants along with their parents and a check variety (Super Basmati) were evaluated at eight sites to determine genetic differences and the magnitude of genotype x environment interaction (G X E) for yield potential, in Sindh province. Genotype, location, year and their interactions were highly significant. The regression coefficient (b) and deviation from regression (S2d) showed significant differences among the mutants/varieties. The mutants Bas. 20/1, Bas. 15/2, Bas. 15/14 and Sonahri Sugdasi-20 (SS-20) were superior in yield to all the entries under evaluation. On the basis of stability parameters, the mutants Basmati 20/1 and Basmati 15/14 have shown good adaptation potential under favourable as well as unfavourable environments.

  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.
