Abstract/Contents:"Many weedy and domesticated plant species can spread by both sexual (seeds) and asexual (vegetative structures) means. A crucial aspect of weed control is understanding the mechanism of weed spread. Evaluating the amount of genetic diversity in a species over a wide area is one way of determining whether spread is mainly by seeds or by vegetative means. We examined the genetic variability of kikuyugrass collected from three golf course sites within its geographical range in California including the San Fransisco Bay area, the central coast, and southern California. Samples from roughs and fairways of each of these locations was compared. The primary thrust of this research was to determine the method of spread of kikuyugrass and to examine the importance of seeds versus vegetative propagules in the establishment of kikuyugrass wehere it is considered an invasive species. Starch gel electrophoresis techniques were used to help clarify the relationships of individuals among and within populations. Using genetic information obtained in this manner we made inferences about the mode of reproduction and the spread of kikuyugrass. Of the 354 plants we examined for genetic diversity, fourteen genotypes were found and only 3 of the 9 loci varied among the genotypes. These were IDH-1, PGI-1, and PGM-2. The genes for MDH-1, MDH-2, PGD-2 and SKD were all homozygous and the genes for MDH-3 and GOT-1 were heterozygous over all plants examined. Two genotypes reperesented 73% of the plants examined and these were found at all three geographic locations."
