Abstract

Patchouli Aceh Lhokseumawe is a patchouli that has a high oil content.  However, the Lhokseumawe species have narrow plant genetic variation due to vegetative propagation. This study aims to analysis broad genetic variability and phenotypes, correlation between growth character and strong yield character to help selection in plant breeding.  The research was conducted at experimental field of the Politeknik Negeri Lampung in April until October 2018.  The research used Randomized Block Design (RBD) with 10 genotype and 3 replications.  Analysis of the data used is ANOVA, if significantly different followed by the LSI 5%, then using variability genotype and phenotype and t test. The result showed that NPL 1 had a better appearance than the Lhokseumawe (local) genotype in the LSI 5%.  Extensive genotype variability was found ini g/plant dry weight character and ton/ha dry terna production, broad phenotype variability was found in all observed characters.  High heritability is found in the characters of stem diameter, wet weight, dry weight, and production of dry ton/ha. Significantly positive phenotypic correlations that have high oil yield are characterized by the characteristics of dry weight, ton/ha dry cattle production, wet weight, and harvest index. Positive genotypic correlations were evident between growth and yield characters, namely the oil yield with leaf length, and leaf width.
