Bipolaris zeicola: physiological races, morphology and resistance on maize
… curvature and pigmentation of 39 isolates of Bipolaris zeicola (Stout) Shoemaker from different geographical areas and representing distinct physiological races were examined. Wide variability in conidial morphology was found among isolates of each race. No association was found between races …

Inheritance and Components of Resistance to Bipolaris Maydis Race O (Maize, Corn, Breeding)
Three different studies using the Bipolaris maydis race O - maize pathosystem were done at the University of Illinois in 1981, 1982 and 1983. The first study was a quantitative genetics study of the inheritance of resistance in 12 families derived from inbreds determined to be highly resistant to …

Analysis and application of the En transposable element and genetic study of resistance to Bipolaris maydis in maize
… is the genetic study of resistance to Bipolaris maydis. This resistance was determined to be monogenically controlled in the 1970's. However, non-monogenic types of resistance were also reported. Data are reported that support a two-gene model of resistance. Two transposable element …

Physiological, biochemical and molecular aspects of induced resistance in maize against Bipolaris maydis infection using a zinc-polyphenolic compound and silicon
Maize leaf blight (MLB), caused by the fungus Bipolaris maydis, has great potential to cause considerable losses in the growth and yield of maize. Higher foliar concentration of silicon (Si) or the use of resistance inducers may be promising alternatives for boosting maize resistance against MLB. …
