| Spatial autocorrelation was applied to microgeographic variations in Korean wild radish, Raphanus sativus var. hortensis Baker f. raphanstroides. Separate counts of each type of join (combination of genotypes at a single locus) for each allele, and for each distance class of separation, were tested for significant deviation from random expectations by calculating the Standard Normal Deviation. Moran's I was significantly different from the expected value in 16 of 112 cases (14.3%). Eleven of these values(9.8%) were negative, indicating genetic dissimilarity among pairs of individuals in the eight distance classes. Populations of wild radish are small in Korea and are distributed with tractors used for fishing. Ocassional cutting of seed-bearing stems as fodder for animals also may bring a high level of gene flow. Thus, disturbance by many anglers, as well as by farmers, may contribute to the fact that the wild radish population of Onsan is unusual in lacking spatial genetic structure. |
