The phaeosphaeria leaf spot of maize in Brazil: evidences of a new etiological agent?

spot, has been observed causing severe damage in all maizegrowing areas of Brazil since 1982 (Fantin, 1994). The causal organism of this disease was initially described in the USA as Phaeosphaeria maydis (Henn.) Rane, Payak & Renfro (sin. Sphaerulinia maydis Henn.), anamorph Phyllosticta sp. (Rane et al., 1966). Doubts regarding the etiology of this disease have resulted in several attempts to ...

Inheritance of Gray Leaf Spot Resistance in Corn

Bayesian inference to study genetic control of resistance to gray leaf spot in maize.

Gray leaf spot (GLS) is a major maize disease in Brazil that significantly affects grain production. We used Bayesian inference to investigate the nature and magnitude of gene effects related to GLS resistance by evaluation of contrasting lines and segregating populations. The experiment was arranged in a randomized block design with three replications and the mean values were analyzed us...

Species of Cercospora associated with grey leaf spot of maize

Grey leaf spot is a serious yield-reducing disease of maize (Zea mays) in many parts of the world where this crop is cultivated. The causal organism associated with the disease is Cercospora zeae-maydis. Two potential sibling species have been recognized as Groups I and II. The DNA sequences for the internal transcribed spacers (ITS1 & ITS2), the 5.8S rRNA gene, elongation factor 1-alpha, histo...
