Abstract

Spathoglottis plicata Blume is one type of orchids with low level of genetic diversity, especially in flower color compared to the other ochids. The experiment aimed was to induce the genetic diversity of S. plicata accession Bengkulu using gamma irradiation to plantlets. The experiment used Completely Randomized Design with 11 doses gamma irradiation (0, 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 Gy). The result showed that the increase of genetic variability of orchid plantlets after gamma-ray irradiation treatment with doses ranged 30-100 Gy. The LD50 of percentage of plantlet survival was 50.74 Gy, seven months after gamma irradiated. The LD30 of percentage of new plantlet formation was 33.78 Gy. There were 7 plant mutants base on shape and color of flower diffrences and 2 plant mutan base on morphological vegetative characteristic.
