Eastern Filbert Blight Resistance in American and Interspecific Hybrid Hazelnuts

RAPD markers linked to eastern filbert blight resistance in

A total of 1,110 decamer primers were screened for RAPD markers linked to a dominant allele in hazelnut (Corylus avellcma) that confers resistance to eastern filbert blight caused by A~zisogrcrinmn anomnl~z. Twenty R 4 P D markers linked in coupling, and five markers linked in repulsion. were found. A seedling population was used to construct a linkage map of the region flanlung the resistance ...

Molecular mapping of resistance to blight in an interspecific cross in the genus castanea.

ABSTRACT A three-generation American chestnut x Chinese chestnut pedigree was used to construct a genetic linkage map for chestnut and to investigate the control of resistance to Endothia parasitica (chestnut blight fungus). DNA genotypes for 241 polymorphic markers (eight isozymes, 17 restriction fragment length polymorphisms [RFLPs], and 216 random amplified polymorphic DNAs [RAPDs]) were ass...

Mapping QTLs for Fusarium Head Blight Resistance in an Interspecific Wheat Population

Fusarium head blight (scab) is one of the most widespread and damaging diseases of wheat, causing grain yield and quality losses and production of harmful mycotoxins. Development of resistant varieties is hampered by lack of effective resistance sources in the tetraploid wheat primary gene pool. Here we dissected the genetic basis of resistance in a new durum wheat (Triticum turgidum ssp. durum...

The Filbert Matrix

A Filbert matrix is a matrix whose (i, j) entry is 1/Fi+j−1, where Fn is the n Fibonacci number. The inverse of the n × n Filbert matrix resembles the inverse of the n× n Hilbert matrix, and we prove that it shares the property of having integer entries. We prove that the matrix formed by replacing the Fibonacci numbers with the Fibonacci polynomials has entries which are integer polynomials. W...
