Col/Nd RI Population

A recombinant inbred line (RIL) population has been developed using two parental strain accessions of Columbia (either Col-3 or glabrous Col-5) and Niederzenz (Nd-1). These lines have been used to map loci involved in natural variation of downy mildew and bacterial pathogen resistance.

Background information

The population of RI lines was developed and donated by Jim Beynon, Eric Holub and Ian Crute, Horticulture Research International, Wellesbourne, Warwick, UK.

To obtain the F1 hybrid plants, one of the Columbia strains (Col-3 or Col-5) was used as the female parent and fertilised with pollen from Niederzenz (Nd-1). One hundred of the F1 plants were selected, allowed to self fertilise and subsequently advanced to the F9 generation population.

The complete set of marker scores for each chromosome may be obtained by following the links below.

The stock numbers of the parental lines are as follows:

N908 Col-3
N1644 Col-5
N1636 Nd-1
