CHROMOSOME LOCATION OF FUSARIUM HEAD BLIGHT RESISTANCE IN 'FRONTANA' SPRING WHEAT

摘要

To determine which chromosomes bear resistance genes to Fusarium head blight (FHB) incidence, severity, and spread. Substantial resources including monetary, have been lost over the last two decades in attempts to control FHB, also known as scab, a fungal disease caused by Fusarium ssp in wheat (Triticum aestivum L.) and other small grains. The main causal agent of FHB is Fusarium graminearum Schwabe teleomorph Gibberella zeae (Schwein). The pathogen causes losses in yield, poor kernel quality, and reduced market value of the kernels due to discolored and shrunken kernels on infected plants. Kernels are also contaminated with myco-toxins, primarily deoxynivalenol (DON) that make kernels not only unpalatable but also noxious to both human and animals (McMullen et al, 1997).
