Transgressive segregation of F₂ maize generation in susceptibility to Fusarium spp.

摘要

Experiments were conducted in Swadzim, Poland to assess susceptibility of F₂ maize generation to Fusarium spp. The hybrids' susceptibility to Fusarium spp. causing foot-rot was diverse; average percentage of infestation fluctuated from 0.6 to 5.7 in the first date of observation. Plants of medium-late hybrid Clarica, regardless of generation, were the most resistant to the infestation by Fusarium spp. Analysis of variance showed that stem base infestation of F₂ hybrid generation in both dates of observation was significantly higher than that of plants of F₁ generation. Similar relations were found in the case of ear infestation by Fusarium spp.
