Abstract
It is intended to provide a pure line plant which is required in constructing a seed propagation variety of orchid. An auxin solution is dropped to unfertilized orchid flowers so as to form seeds based on parthenogenesis. Then these seeds are germinated and haploid plants are selected from orchid plants thus grown. The germinating seeds judges as haploid plants are grown to give pure line plants having doubled chromosomes. Thus, a seed propagation variety of orchid is obtained.

A method of constructing orchid haploid, comprising
- dropping an auxin solution to unfertilized orchid flowers;
- forming seeds based on parthenogenesis, germinating and growing the seed;
- and
- obtaining an orchid haploid.
A method of constructing a seed propagation variety of orchid comprising:
- dropping an auxin solution to unfertilized orchid flowers;
- forming seeds based on parthenogenesis;
- germinating the seeds;
- judging plants grown from the germinated seeds for being haploid;
- selecting the judged haploid plants;
- and
- growing the haploid plants.
The method of constructing a seed propagation variety of orchid comprising:
- dropping an auxin solution to unfertilized orchid flowers;
- forming seeds based on parthenogenesis;
- germinating the seeds;
- judging plants grown from the germinated seeds for being haploid;
- selecting the judged haploid plants;
- and
- growing the haploid plants,
- wherein said judgment as haploid plants are done by measuring DNA contents or the number of chromosomes of samples obtained within a period between one to five months after germination.
