Table 5 Ratio of female-sterile and female-fertile strains transferred in a single asexual generation from mixtures of female-sterile and female-fertile strains

From: Asexual reproduction induces a rapid and permanent loss of sexual reproduction capacity in the rice fungal pathogen Magnaporthe oryzae: results of in vitroexperimental evolution assays

  No. of female-sterile strains recovered/20 strains Mean % of female-sterile strains recovered Comparison with expected 50% ratio Expected % based on conidial transfer evaluation in single culture

  1. The expected percentage based on conidial transfer evaluation in a single culture was calculated by averaging the observed number of conidia transferred for each of the two strains when grown individually
