GENE FLOW AND GENETIC DIVERSITY IN ENDANGERED PLANT POPULATION, MORUS MACROURA MIQ. IN WEST SUMATRA

: In order to clarify the genetic diversity within population and gene flow between population in the endangered
Andalas tree(Morusmcraura Miq.), RAPD analysis was conducted on 24 individuals from 3 Populations (X Koto, Tanjung Raya
and Batipuh) in West Sumatra. The different of genetic diveersities were detected Among Populations of Morus mcraura Miq.
The genetic diversity of Tanjung Raya population of M. macroura (Na = 2, Ne = 1307,H = 0179, I = 0.270) was higher than
Reviews those of Batipuh population(Na = 1, Ne = 1291, H = 0168, I = 0.250) and X Koto population(Na = 2, Ne = 1264, H = 0162, I = 0249). Most of the total genetic diversity of M. macroura (HT= 12:28) was resided within population(HS = 0.225), while
between population(DST)was 0.055. The genetic differentiation was slightly high(GST = 0.244). Total Gene flow across all
Populations was slightly low(Nm= 1,549). There was Significantly correlated between geographic distance and genetic similarity
of M. macroura (r = - 0.186, Mantel t-test = - 3.1305, p = 0.0009).
