Comparative Genomics of the Genomic Region Controlling Resistance to Puccinia Polysora Underw. in Zea Mays L

Polysora rust (Southern Corn Rust) is a major disease of maize in tropical and subtropical region causing yield loss in excess of 45%. The loci governing resistance (Rpp9, RppQ and RppD) have been mapped to 10.01 bins on short arm of maize chromosome 10, which also has genes for common rust resistance like Rp1 and Rp5. With the publication of maize draft genomic sequence we tried to annotate th...

VARIABILITY IN ISOLATES OF Puccinia polysora IN BRAZIL

The main objective of this work was to evaluate the variability of the southern rust pathogen Puccinia polysora in Brazil, based on its virulence on a set of maize (Zea mays) cultivars. Sixty single pustule isolates, from different areas of occurrence of southern rust, were evaluated for their virulence to 50 maize experimental hybrids. Six cultivars showed a clear distinction between susceptib...

MAPEAMENTO DE GENES DE RESISTÊNCIA QUANTITATIVA A Puccinia polysora EM MILHO*

Mapping of resistance genes to Puccinia polysora in maize The objectives of this study were to identify microsatellite markers linked to resistance gene of resistance to Puccinia polysora and to estimate the phenotypic effect of these genes on two monocyclic variables lesion, number and length. Two inbreed lines with different degrees of resistance (Z-95 and Z-93), the hybrid (Z-95 X Z-93) and ...

Resistance to Rhopalosiphum padi (Homoptera: Aphididae) in three triticale accessions.

Experiments were conducted to identify and characterize host plant resistance to bird cherry-oat aphid, Rhopalosiphum padi (L.), in various wheat and wheat-grass hybrids. Initial tests screened for resistance to R. padi among 12 grass accessions (eight wheat [Triticum aestivum L.], three triticale [XTriticosecale Wittmack], and 1XElytricum [Elytrigia elongata [Host] Nevski x Triticum aestivum h...

Cluster Analysis , an Approach to Sampling Variability in Maize Accessions 1

Cluster analysis is frequently used to claSSify maize (Zea mays L.) accessions and can be used by breeders and geneticists to identify subsets of accessions which have potential utility for specific breeding or genetic purposes. Phenograms can be utilized to define subsets of accessions on the basis of dissimilarity coefficients. Phenograms created using cluster analysis depend on the clusterin...
