Abstract A description is provided for Cercospora sorghi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Sorghum vulgare, S. sudanense, S. halepense and S. dochna. DISEASE: Grey leaf spot of sorghum, Sudan grass, Johnson grass and broomcorn. Spots usually first form on the lower leaves and infection gradually spreads upwards; they are elongate, somewhat delimited by the veins and individually > 1 cm long and 3-5 mm in width. Coalescence can take place, to give larger stripes or patches and kill large areas of the leaf. The colour (shades of red to black, light brown or yellowish) of the lesions varies with that of leaf colour. The deep coloured spots tend to have lighter coloured outer rings than the paler ones where the margins are darker. Colours darken with age and a faint zonation may be found (10, 516). GEOGRAPHICAL DISTRIBUTION: Widespread (CMI Map 338, ed. 3, 1974). TRANSMISSION: No studies reported; conidia presumably air-dispersed and spread from host debris.

SUMMARYAnalysing the stability and adaptation of cultivars to different environments is always necessary before recommending them for planting on large areas. Additive main effects and multiplicative interaction (AMMI) models have been used to analyse genotype-by-environment interactions (G × E). AMMI models require data with homogeneous variance, normal errors and additive effects. However, agronomic data do not always conform to these statistical assumptions. The objective of the present study was to analyse G × E interactions for severity and incidence of grey leaf spot, a foliar disease in maize caused by Cercospora zeae-maydis, using a generalized AMMI model. Data were collected and evaluated for 36 maize cultivars from experiments carried out in nine Brazilian regions in 2010/11 by the Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA – Milho e Sorgo). Only two of three stable genotypes defined by a quasi-likelihood model with a logistic link function could be recommended for their desirable agronomic characteristics. Four growing locations in which the genotypes were stable were identified, but in only one of these was stability associated with very severe grey leaf spot disease. Cultivars adapted to specific locations with low percentage disease severity were also identified.
