Genetic Relationships of Some Zingiberaceae by Isozyme Patterns

Abstract

The study was carried out in fifteen species of Zingiberaceae, including : Krachai (Boesenbergia pandurata Holtt.), Krachai-dam (Kaempferia parviflora Wall.ex Baker), Siam cardamom (Amomum krervanh Pierre), Kathu (Zingiber zerumbet Smith), Kha-min-khao (Curcuma mangga Valeton), Turmeric (Curcuma longa Linn.), Kha min-dam (Curcuma aeruginosa Roxb.), Zedoary (Curcuma zedoaria Roscoe), Galanga (Alpinia galanga Sw.), Kha nam (Alpinia allughas Roscoe), Kha-yuak (Alpinia nigra (Gaerth) B.L.Burtt), Kha-yai (Alpinia siamensis Schum.), Ginger (Zingiber officinale Roscoe), Phlai (Zingiber cassumunar Roxb.) and Phlai-dam (Zingiber ottensü Valeton). Isozyme patterns of acid phosphatase, esterase, malate dehydrogenase and peroxidase showed one to four bands of isozyme. Genetic relationships were classified into four groups. Group A, with 0 – 72% similarity, included Kha-nam and Phlai. Group B, with 0 – 72% similarity, included Turmeric and Zedoary. Group C, with 0 – 32% similarity included Galanga, Kha-yuak, Kha-yai, Kha-min-khao, Siam cardamom and Krachai and Group D, with 0 – 16% similarity, included Kha-min-dam, Ginger, Phlai-dam, Kathu and Krachai-dam.
