INTRODUCTION  Menoreh durian is an important commodity and superior fruit from Kulon Progo Regency Specific Regency Province Yogyakarta. The superiority of the durian fruit is in its delicious taste and thickness of flesh. There are two varieties of superior durian from Kulon Progo: The Yellow Menoreh and The Pink Menoreh durian. The specific color of Pink Menoreh durian is the pink color of flesh.  In order to obtain the decision of Menoreh durian as new superior variety the identification and classification of the durian must be carry out. Since it is difficult to find out the distinction between the durian variations based on morphology characters only, we also used the molecular method for identification. Molecular identification method with RAPD was used to obtain the plant identification because the method has no environment effect influence. The research aimed was to obtain the molecular identity of Menoreh durian variety and its classification in order to find decision of its superiority as a new variety. The decision of Menoreh durian adds nationally varieties that can be declare of the biodiversity identity of locally Kulon Progo Regency.

Seventy four characters collected from stem, leaf, flower, fruit and seed were compared with that of Petruk, Sukun, and Sunan durian planted in Karanganyar Central Java. Similarity index matrix among the cultivars resulted of morphology data with Jaccard method (1) followed by dendogram analysis. Molecular identification and classification of Menoreh durian with PCR-RAPD method was carried out in our laboratory. Material for research was 11 axesion of durian consisted of: Yellow Menoreh (1, 2, and 3), Pink Menoreh, Petruk, Sunan, Sukun, Montong, Sitokong, Kani, and Aspar durian. The research was carried out of as follow: (1) DNA extraction, (2) quantity and quality DNA test, (3) DNA amplification, (4) electrophoresis, (5) DNA visualization, and (6) DNA result analysis.  The DNA extraction method for Salak was used for durian DNA extraction (2). A 150 mg of young leaf durian was grinded with mortar followed with addition of 1,000 μl of CTAB solution and centrifugation at 13,000 rpm for 5 minutes. Supernatant (in green color) was separated and then incubated at 65 °C. After 1 hour the solution was added with 800 l of chloroform and centrifuged at 13,000 rpm for 7 minutes. The supernatant was then placed in the eppendorf tube and precipitated with 20 l of Na Acetate (pH 7.5) and 650 l of Isopropanol, followed by centrifugation at 13,000 rpm for 7 minutes. The DNA pellet was then separated from the solution, added with 70 % of cold ethanol and centrifuged at 13,000 rpm for 5 minutes. DNA pellet was dried for 2 hours, resolved in Tris EDTA sterile solution and store at 4 °C.  DNA amplification process (PCR-RAPD) was used 18 single primers of Operon Alameda: OPA-1 - OPA-18.    RESULTS AND DISCUSSION  A. Identification and classification based on plant morphology characters  Based on 74 morphology characters results analysis from stem, leaf, flower, fruit and seed of Pink Menoreh durian, compared with that of Yellow Menoreh, Sukun, Petruk, and Sunan durian, the similarity index value could be calculated by Jaccard method and arranged as a matrix as described in Table 1.  Table 1. Similarity index value  of Durian Pink Menoreh and others.                   Durian Petruk Sukun Sunan Yellow Menoreh Pink Menoreh Petruk 100         Sukun  43.24 100       Sunan 59.45 45.94 100     Yellow Menoreh  43.24 45.94 45.94 100   Pink Menoreh  41.89 50.00 41.89 63.51 100  Similarity index value of Pink Menoreh durian showed 41.89 % and 63.51 % in the lowest and highest similarity, respectively. Low similarity index showed the highest distinction between Pink Menoreh and the others cultivars. More than 20 % in the distinction of cultivars from the others showed the difference among varieties (3), therefore supported the idea that Pink Menoreh durian is a new variety. Based on the similarity index value matrix, the dendogram could be arranged used the Un-weighted Pair-Group Method Using Arithmetic Average (UPGMA).  Classification of durian cultivars based on the morphology characters in the dendogram resulting two groups: group I (Menoreh 1, Menoreh 2 and Sukun) and group II (Petruk and Sunan). The Pink Menoreh durian had a 63.51 % distinction with that of Yellow Menoreh durian. These findings support the previous report (3) that Pink Menoreh durian is standing as a variety.   Figure 1.

Identification and classification of durian based on molecular analysis (PCR-RAPD)  Molecular analysis with RAPD technique used 18 single primers resulted 10 primers that showed DNA polymorphism and clear bands. Amplification DNA with primer of OPA-1 showed three patterns of polymorphism bands (Figure. 2)             Figure 2. The RAPD results with OPA-1 and OPA-2 primers.             Figure 3. The RAPD results with OPA-13 primer.              Figure 4. The RAPD results with OPA-17 primer.  Amplification with OPA-2 showed more variations (band number 1-6 consisted 7 patterns). Menoreh 3 was differing with that of Menoreh 1 and Menoreh 2 at 300 and 380 base pairs of PCR products. DNA of Sukun durian showed differences of bands pattern at 250, 300 and 380 base pairs; and the 2,000 bp band was only showed in Sukun cultivar. Amplification of DNA durian with OPA-13 primer resulted clear bands.   Amplification of DNA resulted 3 patterns: I. The two bands pattern: Sitokong and Kani durians originally from Thailand (number 9 and 10, respectively); II. The three bands pattern: Yellow Menoreh durian (number 1, 2, and 3), Petruk, Sunan, Sukun, Montong and Aspar durian (number 5, 6, 7, 8, and 11, respectively); III. The four bands pattern: Pink Menoreh durian. Pink Menoreh DNA (number 4) had different pattern with others via 250 bp of PCR products. DNA amplification with OPA-17 primer showed different pattern with that of the Sukun durian (number 7) as shown with 500 and 1050 bp of PCR products. Also, using OPA-19 primer, the Sukun DNA consisted of 5 bands comparing with the others (2 or 3 bands). Salak DNA amplification with 6 primers (OPA-11, OPA-16, OPA-17, OPA-18, OPX-15 and OPX-17) was resulted 3-6 polymorphic bands with 250-3000 bp PCR products (2). Using RAPD for genetic diversity study of coconut cultivars was resulted 250-3080 bp (4). Short primer (10-mer) in general can amplify DNA sequent less than 4,000 bp. The DNA amplification with OPA-4 primer (number 4) showed the differentiation of the Pink Menoreh DNA with the others in 490 bp of PCR products. DNA amplification with OPA-18 resulted different bands with the others at via 400 and 480 bp of PCR products.  The Yellow Menoreh 1 and Yellow Menoreh 2 had the lowest distinct therefore the may originated from same parent (Table 2). Yellow and Pink Menoreh durian was durian originated from Kulon Progo Regency. The genetic difference among cultivars than was analyzed using the Jaccard method (1).  Genetic distinct between Pink Menoreh and Yellow Menoreh was between 0.529-0.588. The genetic distinct more than 20 % supported the position of one accession differ with other variety (3). The genetic distinct matrix was then used to arrange a dendogram by UPGMA (1). Based on the RAPD results, the    Identification and classification of Durian                                                                                    Nandariyah  30  durian cultivars were grouped within three groups: the first group (consisted of Menoreh, Petruk, Aspar, Sunan and Pink Menoreh durian), the second group (consisted of Montong, Sitokong, and Kani durian originally from Thailand), and the third group consisted of the Sukun variety. As shown in the dendogram, the Pink Menoreh durian was showed as a variety.            Figure 5. The RAPD results with OPA-4, OPA-18 and OPA-19, respectively.                       Table 2.
