Reference A molecular marker map in 'Kanota' x 'Ogle' hexaploid oat
(Avena spp.) enhanced by additional markers and a robust
framework

Remarks This map set, published by Wight et al., 2003 (Genome
46:28-47), is an enhancement of the hexaploid oat map
published by O'Donoughue et al, 1995 (Genome, 38:368-380).
The original work was conducted in a recombinant inbred (RI)
population derived from Avena byzantina C. Koch cv. 'Kanota'
x A. sativa L. cv. 'Ogle'. The current work adds 607 new
markers, some of which have been mapped in an expanded set
of RI lines (133 vs. 71). Where possible, linkage groups
are joined and assigned to chromosomes based on monosomic
and/or nulisomic lines (Kianian et al. 1997, Genome, 40:
386-396; Start 2000, Thesis; Fox et al. 2001, TAG 102:
320-326). Chromosome assignment remains only partially
resolved and ambiguous (see Table 4 in Genome 46:28-47).
Numerical linkage group names have been preserved from
O'Donoughue et al. (1995), with numbers concatenated to
indicate the merging of linkage groups ('_' = aneuploid
evidence, '+' = other evidence). Due to the high density
of markers in some regions, a robust framework was developed
to resolve linkage among 286 good quality markers. The
remaining 880 markers were placed within the most likely
framework intervals using chi square tests. The remark
'Marker is/is not a framework marker' indicates whether the
marker is part of the framework. If the marker is not part
of the framework, then the linear coordinate of the placed
marker is estimated by applying a scaling factor to the
distances between it and adjacent framework markers such
that the framework interval remains constant. The remark
'Marker Placement Value = xxx cM' provides an indication of
how well the marker fits within the interval into which it
is placed. Ideally, this value should be approximately
equal to the length of the interval into which it has been
placed. When an interval contains many placed markers, the
order implied by the coordinates is not necessarily correct.
The true order within a dense cluster of markers can only
be determined in a much larger population.
The interactive maps place the framework markers on the left
and highlight them yellow.
