Interpretive Summary:

Technical Abstract: Progress continues to be made in the effort to transform potato from a tetraploid outbreeding crop into a diploid inbreeding one. This transformation will ultimately lead to more efficient breeding and cultivar development. A variety of genetic resources will be required before a cultivated diploid potato industry can be realized. One such resource is the development of recombinant inbred line (RIL) populations. RILs can be utilized for the mapping of useful traits and as inbred parents for hybrid development. Three genetically diverse populations, named DM, J93, and C545, are being developed to serve these purposes. Genotypic and phenotypic data are being collected alongside the development of the lines. Clones are being genotyped at each generation in order to measure homozygosity. Phenotype data are focused on traits associated with seed productivity, such as flowering rate, seed yield, seed germination rates, and seedling vigor. Studies have been conducted to determine if a 24 hour photoperiod offers advantages in flowering rate over a photoperiod of 18 hours. The DM population is expected to be completed by early fall and preliminary phenotype data will be presented.
