Abstract/Contents:"The Legislative Commission on Minnesota Resources initiated a program to develop a viable seed industry for the production of native grasses and forb[s]. A part of this program is to measure the amount of genetic diversity among and between populations in Minnesota. This information will be used to develop strategies for the distribution of seed in land reclamation and for management of seed production to maintain the genetic diversity of commercial seed lots. Two grasses, Andropogon geradii and Schizachyrium scoparium, and two forbs, Monarda fistulosa and Liatris sp., were used in this study. Genetic diversity of populations was measured using morphological traits and isozyme analysis of 30 to 50 individuals from each the 13 to 49 populations. Thirteen enzymes systems were examined to detect polymorphisms. Isozyme polymorphisms have been detected in Litaris populations for PGM, MDH and ACP. No isozyme polymorphisms have been detected in grass populations. Morphological characteristics were measured in a common nursery to remove genotype x environment interactions. Variation in height, number of stems and number of inflorescences were observed within and among grass populations. Litaris populations varied in leaf number, width and length and shoot dry weights."
