Kemajuan Genetik Mutan Nilam (Pogostemon cablin Benth.) Generasi MV2 Hasil Irradiasi Sinar Gamma 60 Co

Mutation breeding is a method of molecular approaches in expanding the genetic variation of plants that do not reproduce by sexual crossing, as in plants that reproduce vegetative patchouli. This research was conducted in order to evaluate the progress of genetic clones of patchouli given gamma ray irradiation. The experiment was arranged using a randomized block design with three replications of 25 irradiated. Based on the analysis of heritability in character angle branches, plant height, diameter branches, and yield herb / plant with medium and high criteria of criteria contained in the character of leaf angle and length of the branch. Special genetic progress with the criteria of being located on the corner of characters long leaves and branches. The results obtained from the highest genotypes were 14.74 tonnes / ha - 23.96 tones / ha. Keywords: Nilam, radiasi gamma, genetic gain
