To identify the seedlings from controlled pollination between one paternal tree and three maternal trees of Japanese red pine, cpSSR markers of the paternally inherited haploid genome were analyzed in two year old 114 seedlings of full sib families. Individual specific DNA fingerprint like haplotypes of the parental trees were determined by PCR with three cpSSR primers. Haplotypes of the 114 seedlings were also identified by PCR with the same primers. On the basis of the comparison of cpDNA haplotypes of the 114 seedlings with those of the parental trees, 14 seedlings revealed to have distinguished haplotypes from those of the paternal tree. It was tentatively concluded that they were generated via pollination with the non-paternal trees. A seedling of Gangwon30 revealing non-paternal haplotype might have been generated via self pollination with the pollens of maternal tree through improper emasculation or contamination during artificial pollination. DNA fingerprint like cpSSR profiles observed in this study could be successfully applied to the various plant forensic analyses, such as identification of siblings of individual trees, asexually reproduced ramets of a specific clone, vegetatively propagated individuals via tissue culture, and pure full sib progenies.

When haploid plant would be appeared by the anther culture, the large quantity of young plant multiplied maternal inheritance and the same pure line rapidly in the short length of time, which will be effected to cut down much expences efforts and time for the production of seeds or seedlings. Therefore, the development of the technique for this would be much profited in the country industry. In the late of a few years studies were early attempted in this field, but up this time there were a few success of plants only and none of perennial plant. In this status of the country condition required earnestly for the development of the green industry, this researcher attempted to culture the anther of late uninucleate microspore or early binucleate microspore of the Prunus mume and other three psecies, economic trees estimated specially economic, on the place of Modified Murashige and Skoog's medium supliment with Kinetine, 2.4-D, and N.A.A for inducing haploid plants. The obtained results were as follows: 1. 2,000 anthers were cultured and there were shown that 2N callus in Prunus mume had 82 as 4.1%, 2N callus in Prunus tomentosa 15 as 0.8%, 2 N callus in Prunus salisina 75 as 4% 2. N callus had shown 40 as 2% from Prunus armeniaca var. ansu only, and the other trees showed all 2N callus. 3. Callus had appeared in every tree but 2N callus appeared was all filaments and there showed from only connective tissue N callus appeared was all from anther locule inside. 4. Then Prunus armeniaca var. ansu only was not callus of somatic anther tissue origin, but as there was callus origined from microspore which was changed in to swollen microspores or polynucleate microspores, it was certained to need haploid plant.
