Keragaman Genetik Plasma Nutfah Anggrek Spathoglottis


Orchid need to be a species or cultivar to avoid from totally extinct. They can be used as the source of genetic variability in developing new superior varieties. Variability of the crop is very importance in plant breeding program to improve plant breeding program to improve plant genetic quality in the future. The research was conducted in Indonesian Ornamental Crops Research Instite (IOCRI) from July 2004-February 2005. The aim of the research was to study the genetic variability and heritability of germplasm collection of Spathoglottis orchid. Randomized completely design was used consisted of 15 orchid genotypes. Five clones from each genotype were used as replication. The result indicated that wide genetic variability was related to length and width of leaf, number of shoot increatment, length and width of flower, length and width of lip. Characters, such as number of shoot increament, length and width of leaf, length and diameter of flower stalk, length and width of lip, ratio of lip length-width, length an width of flower showed high heritability value.
