EKSPLORASI DURIAN (Durio zibethinus Murr.) LOKAL BERPOTENSI UNGGUL SEBAGAI POHON INDUK DI KECAMATAN NGRAMBE, NGAWI

The nature of durian based on specific area gives a wide diversity of phenotype. This research objective was to inventoried the local durian of Ngrambe as well as to obtain potentially superior local durian as prospective mother trees. The research was conducted in Ngrambe sub-district, on October 2015 until Aprill 2016. This used the explorative descriptive method. Determination of sample point used the non-probability method of snowball sampling type. Primary data include the morphology of plant characters, trunks, leaves, flower, fruits and seeds and their superiority. The data of the research were analyzed by SIMQUAL (Similarity for Qualitative) function based on the DICE coefficient on NTSYS v.2.02. The data cluster and dendrogram analyses were determined by Unweighted Pair-Group Arithmetic Average (UPGMA) method. The result of DICE coefficient analyses of 58 local durian accession based on the phenotypic character of vegetative and generative organs ranged from 0.84-1.0. The phenotypic character of the vegetative and generative organ from 3 local durian accession superior potential ranged from 0.7 to 0.8. In conclusion, the accession of local durians which were Miyem and Rusmiyati have advantage and potential as prospective parent trees
