CHARACTERIZATION STRAINS OF GIANT GOURAMY FROM SOUTH KALIMANTAN JAMBI, MAJALENGKA, AND TASIKMALAYA (Osphronemus gouramy Lac.) BASED ON TRUSS MORPHOMETRIC  

The first step in breeding program  of fast-growing varieties of giant gouramy is the collection and characterization of giant gouramy strains  to be used as a source of gene source in producing new variety of giant gouramy. Several strains and  varieties have been collected i.e. O. gouramy such as South Kalimantan (K), Jambi (J), Majalengka (M), and Tasikmalaya (T). The aim of this experiment  was to determine the morphological diversity among these collected strains using truss morfometrical method. Principal component analysis followed by cluster analysis were used to identify the pattern of morphological variability among strains and varieties.

During October 2015, 704 giant gouramy (O. gouramy) were collected from 12 family. The Fish used were 16 months old. The family were KK, JJ, MM, TT, KJ, KM, KT, JK, JM, MJ, MK, and TJ. The fish were 950.29±311.39 grams in weight. ldentiflkasi strain refers to Soewardi (1995). The method was conducted using morphometric measurements by determining the specific points along the body of the fish and then connect the dots so that the fish's body was divided into several space truss. We then measured the length of the lines in each cell. Truss morphometric characters holding carp made of eight points along the body and produce 16 characters truss (Setijaningsih, et al 2007).

Truss morphometric characters were observed in male and female candidates, a combination of all populations in the family, and discriminant analysis performed on all families.

Data were analyzed by using the character size of the program SAS and SPSS version 16. The results showed that dendrogram regarding the relationship between giant gouramy on the male and female show no 10 groups on the male and 10 groups on the female.

On the pure galur closest family tree occurs on the population M, T, and K. The population of J have the farthest family. The family tree of entire populations indicates 10 groups. The population M, T, and K have the nearest family.
