Link to Internet Resource: Paragon NIL Library Genotyping Data The Paragon Library was developed at JIC and currently consists of around 350 lines. The project involves crossing different combinations of genes, QTLs and mutations into the common background of Paragon and then studying the phenotypic effects. NILs are currently available for multiple alleles of: Rht-D1, Rht-B1, Rht8, Lr19, 1BL.1RS, Yield (7B), Grain Size (5A, 7A) and more than 10 Heading Date QTL. Further lines will be added in the future.
