Vol. 26, No. 1, 2009Indonesian Agricultural Research AbstractsMSQ-P1(C0) was 4.68 t/ha. These yields were not significantly different from the control cultivarsSrikandi Yellow-1, Srikandi White-1, Bisma, Lamuru, and MS-2. Plant aspects, husk cover, and ear aspectwere scored 1 and 2. The intra-population improvement method was done to increase the status C1 toselected S1 families from the F2 generations. The S1 families were evaluated using an incomplete blockdesign alpha lattice with two replications with a selection intensity 8-10%. MSQ-P1(S1)C0 and MSQ-K1(S1)C0 were evaluated in Maros and Bajeng experimental farm, respectively. The results showed thatgrain yield (w.c. 15%) was 6.31 -7.49 t/ha for family selected of MSQ-K1(S1)C0 and 5.93-7.58 t/ha ofMSQP1(S1)C1. Plant aspect, husk cover, and ear aspect of the two populations were 1-2, position of earwas middle of plant height, and moderate resistance to leaf blight and rust.F50 PLANT STRUCTURE050 AZIZ-PURWANTORO.Phylogenetic of orchids based on morphological characters.

Ilmu Pertanian ISSN 0216-4214(2005) v. 12(1) p. 1-11, 1 ill., 2 tables; 14 ref.ORCHIDACEAE; SPECIES; PHYLOGENY; PLANT ANATOMY.Morphological relationships among species orchids is necessary to orchid breeder in obtaining goodhybrids in perennial plants. Closely related among species orchids would increase their crossingopportunity. The objectives of this study was to classify orchid into cluster according to their similaritiesin phenotypic characters. The phenotypic characters observed were plant height (cm), leaf length (cm),leaf width (cm), ratio of leaf length and leaf width number of flowers per inflorescence, lenght of flowerstalk (cm), flower diameter (cm), sepala lenght (cm), leaf colour, type of pseudobulb growth and floweraroma. Relationships among 16 types of species orchids was analyzed according to cluster analysis withagglomerative method (Everitt, 1993). The cluster analysis showed that Phalaenopsis consisted of onecluster, based on the similarities in type of pseudobulb growth, characteristics of plant height and leaf,number of flowers per inflorescence, length of flower stalk, flower diameter and sepal length. Dendrobiumconsisted of four clusters, because of the difference of flower characteristics. Meanwhile, B. lobii, A.miniatum, Vanda tricolor, and G. scriptum has one cluster, respectively.F70 PLANT TAXONOMY AND GEOGRAPHY051 SUHIRMAN, S.[Toxicity of Zingiber zerumbet extracts against Artemia salina].

The present work was to study the toxicity of extract of Z. zerumbet used brine shrimplethality test (BSLT) method and A. salina as bioindicator. The raw material came from Bogor, Subang,Sumedang and Garut. The method of raw material quality determining used Materia Medika Indonesia(MMI) such ash content, ash insoluble in acid, water and alcohol soluble extractives and also fiber, starchand curcumin contents. Extracts were made by maceration combined with stirring and 3 types of solvents,such as polar (methanol), semipolar (ethyl acetate) and non polar (hexane). The chemical compounds wereanalyzed by thin layer chromatography (TLC) with toluene: ethyl acetate: acetic acid = 8:2:2 drops as aeluen and 50% sulphuric acid as spray and GCMS. The result showed that there was variation between24
