Evaluation of maize hybrids for kernel colonization byFusarium moniliformeandF. subglutinans

摘要

Maize kernels from six commercially grown hybrids were collected from various localities for three seasons. The incidence of kernel colonization byFusarium moniliformeandF. subglutinanswas determined by plating out 400 representative kernels per sample onto aFusariumspp. selective medium. Regression analysis (Y=a+bX) was used to determine the relationship between the average incidence of infected kernels of all hybrids at a locality (X) and the observed disease incidence (Y) within a hybrid. Comparisons of the linear models of each hybrid combination indicated that maize hybrids did not differ significantly with regard to FmoniliformeandF. subglutinanskernel infections.
