Genetics diversity analysis of durian landraces in serang regency base on morphological and isozymes characters

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 landraces from four locations were subjected to morphological studies and isoenzymes analysis. The obtained data wem analyzed for genetics relationship among landraces base on morphological and isoenzymes characters and compatibility between morphological and isoenzymes characters. Base on fourteen morphological characters there were 54 % of dissimilarity level indicates medium morphological variability. lsoenzymes analysis by using 7 proteins resulted 39 bands, and genetfcs variability of evaluated trees was 93 % of dissimilarity level. The concurrence analysis on morphological and isoenzymes analysis result, showed the vety weak Rohlf correlation value (r=0,074). This result was indicated that grouping of durian landraces should be using joint of morphological and isozyme analysis. Joint morphological­ isozyme cluster analysis showed that genetics variability among evaluated trees were 60 % of dissimilarity level, and at 53 % level dissimilarity, the durian landraces in Serang Regency should be classified into three groups i.e., 1) Seureuh, Sawah, Pedes, Tolaksana, Potret, Rampayak, Onder, Belu, (2) Balingbing, TM, Paok, Maslay, Emas, Puso, Liter, and 3) Montong, Chanee, and Camat.
