Abstract
LouAu (Louise/IWA8608077) (MP‐7, NSL 511036) is a wheat (Triticum aestivum L.) recombinant inbred line population developed by the USDA‐ARS, with Oregon State and Washington State Universities, from a cross between the soft white spring cultivar Louise and the white facultative Iranian landrace IWA8608077. The population was developed by single seed descent from the F2 generation to the F5 generation. The population has 150 F2:5 recombinant inbred lines and has been used to study the genetics of resistance to root‐lesion nematodes (Pratylenchus neglectus and P. thornei), and root architecture. The 26 linkage groups identified include 30 codominant simple sequence repeat markers and 2008 single nucleotide polymorphic markers from the Illumina 9K wheat single nucleotide polymorphism chip. Chi‐square analysis shows 21 to 95% of identified polymorphic markers within individual linkage groups were in segregation distortion. The population frequency distributions have a normal distribution for the measured traits P. neglectus resistance, root length, root weight, root lignin content, and plant height. The population frequency distribution has a bimodal distribution for P. thornei resistance, left skewed for lateral root number and right skewed for growth stage. This population has shown potential for mapping resistance to other soilborne pathogens as well as abiotic stresses and will be useful in that endeavor.
