Abstract

ABSTRACTCommercial production of oil palm ramet requires the guarantee of high genetic stability. The objectives of this research were to determine 1) genetic diversity of ortet as source of explant, and 2) genetic stability of ramet derived from ortet propagated through tissue culture. Genetic stability analysis was done using ramet from five Tenera (D×P) oil palm ortets.As many as 20 ramets were randomly chosen from each ortet. A total of 100 ramets were used for genetic stability analysis. Genetic similarity analysis was analyzed using NTSyspc version 2.1 software with method Similarity for Qualitative Data and Unweighted Pair Group Method Aritmatic (UPGMA). The results indicated 20 SSR primer pairs were polymorphic and could form 44 alleles. As many as 80% of ramets from IS 3 ortet showed genetic similarity ranged from 97-100% to the ortet. All ramets derived from IS 10, IS 20 and IS 40 ortet had 90-100% of genetic similarity to its respective ortet. Futhermore, 95% of ramets from IS 39 ortet had 97-100% of genetic similarity to the ortet.Keywords: Elaeis guineensis Jacq., genetic similarity, tissue culture

Abstract

Oil palm is a perennial oil crop that contribute the most important source of vegetable oil in the world. Oil palm breeding cycle take a long period, therefore molecular marker-assisted selection (MAS) is required to shorten the selection time. This MAS require the associated marker to desired trait, particularly for yield and the component that as a complex trait and depend on genetic background. The aim of this study was to obtain SSR marker that associated with average of bunch weight (ABW). Plant material was used in this study is Tenera population derived from Deli Dura x AVROS Pisifera. Seven SSR markers from public database were associated to ABW trait. Molecular data analysed for SSR markers profile which consisted of allelic diversity, heterozygosity level, and polymorphism information content (PIC). Association between SSR markers to ABW traits was performed with single marker analysis using one way analysis of variance. The results showed that SSR markers were able to amplify DNA with two to three number of alleles with the average of 2.3 alleles per locus. ABW trait for this population was significantly associated with mEgCIR3428 marker. This marker may be used in the selection of Deli Dura and AVROS Pisifera palm on the next selection cycle.Keywords: Average of bunch weight, AVROS Pisifera, Deli Dura, single marker analysis
