Analisis keanekaragaman genetik durian lokal serang berdasarkan penanda morfologi, isozim, dan gabungan morfologi-isozim

Abstract

Serang regency was known has high diversity of Durian (Durio zibethinus Murr.) landraces. In order to elucidate the genetics variability of the diversity, eighteen iandraces from four locations were subjected to morphological studies and isoenzymes analysis. The obtained data were ana:yzed for genetics relationshii) among landraces base on morphological and isoenzymes characters and compatibility between morphological and isoenzymes characters. Base on twelve morp:1ological characters there were 58 % of dissimilarity level indicates medium morphological variability. lsoenzymes analysis by using 7 proteins resulted 39 bands, and genetics variability of evaluated tree5 were 93 % of dissimilarity level. The concurrence analysis on morphological and isoenzymes analysis result, showed the very weak Rohlf correlation value (r=0,57). This result vVas indicated that grouping of durian landraces should be using joint of rnorphological-isozyme analysis. Joint morphological-isozyme cluster analysis showed that genetics variability among evaluated trees were 58 % of dissimilarity level, and at 51 % level dissimilarity, the durian landraces in Serang Regency should be r;lassified into four groups i.e., 1) Seureuh, Pedes, Sawah, Paok, (2) Balingbin\j, Emas, Puso, Tolaksana, Potret, Liter, Maslai, Onder, TM, (3) Belu, Carnal, and 4) Montong, Chanee, and Rampayak.
