To study the intergeneric crossing between orchids of Phalaenopsis sp. and Vanda Tricolor, three species of Phalaenopsis sp. (Phalaenopsis Joane Kileup June, Phalaenopsis Pinlong Cinderella, and (Phal. Fortune Buddha x Phal. Princess Kaiulani) were crossed reciprocally with Vanda Tricolor in time-different value (within the first, second and third week after full opened flower). The crossing of phalaenopsis sp. and Vanda tricolor was compatible, and the use of Phalaenopsis sp. as male parent had better probability in producing fruits rather than the opposite. The crossing which was done at the first and the second weeks after blooming produced more fruit than the crossing at the third weeks after blooming, even through it did not affect the success of crossing, time of fruit formation, and duration of fruit hanging.

ABSTRACT
High Annealing Temperature-Random Amplified Polymorphic DNA (HAT-RAPD) markers were used to study the genetic relationship among 15 samples of orchids in the genus Eria. DNA amplification of 31 random primers out of 72 random primers was successful. In this study, we selected 21 random primers with clear amplified products for further genetic analysis. The result showed significant differences among all samples and also showed specific bands in each sample. Moreover, we found 21 random primers which tended to be DNA markers for further identification. Based on polymorphic bands, a dendrogram was constructed. Genetic similarities among 15 samples of Eria species were demonstrated, and the samples could be classified into 3 groups with similarity coefficients ranging from 0.36 to 0.85.

The pollination biology of North American orchids brings together, for the first time, a comprehensive treatment of this information for all native and introduced North American orchids found north of Mexico and Florida. It provides detailed information on genetic compatibility, breeding systems, pollinators, pollination mechanisms, fruiting success, and limiting factors for each species. Distribution, habitat, and floral morphology are also summarized. In addition, detailed line drawings emphasize orchid reproductive organs and their adaptation to known pollinators. This, the first of two volumes, furnishes a brief introduction to the general morphology of the orchid flower and the terminology used to describe orchid breeding systems and reproductive strategies. It treats the lady’s-slippers of genus cypripedium, subfamily cypripedioideae, and nine genera of the subfamily orchidoideae, including the diverse rein orchids of genus platanthera.
