New molecular evidence on genome relationships and chromosome identification in fescue (Festuca) and ryegrass (Lolium)

Article Abstract:

The molecular basis of the close homology between fescue (Festuca) and ryegrass (Lolium) has been investigated through Southern blots with DNA-DNA hybridization and genomic in situ hybridization. Regions of high homology were found on F. pratensis, providing new markers for chromosome identification. In addition, rDNA restriction patterns show that F. arundinacea is a hybrid of F. pratensis and F. glaucescens.

Four QTLs determine crown rust (Puccinic coronata f. sp. lolii) resistance in a perennial ryegrass (Lolium perenne) population

Article Abstract:

Linkage mapping and QTL analysis were used to unravel the genomic organization of crown rust resistance in a Lolium perenne population. The results are of major importance for understanding the molecular back-ground of crown rust resistance in ryegrasses.
