Rose scented geranium pelargonium graveolenes plant `Safal`

Abstract

The invention relates to a new, distinct and unique plant of rose scented geranium Pelargonium graveolens `Safal` derived from a rare seed-set in cultivar `Bipuli,` apparently the result of hybridization between largely sterile populations of the cultivar accessions `Bipuli` and `Hemanti`, possessing the following combination of characteristics namely demonstrated vigour in the essential oil yield related traits in great measure and out yielded all the other accessions; the essential oil of the plant has 89% rhodinol content in which citronellol to geraniol ratio is approximately 1:1 and the contents of isomenthone, menthone, 10-epi-.gamma.-eudesmol, 6,9-guaiadiene, decanoic acid and isodecanoic acid were relatively lower than in the oils of accessions `Bipuli` and / or `Hemanti`, this plant can be propagated vegetatively through stem cuttings and suitable for commercial cultivation in large scale.

Description

Latin name of the plant claimed: The plant claimed is Pelargonium graveolens var. `Safal`.FIELD OF INVENTIONThe present invention is related to the development of a novel high essential oil producing plant obtained through a unique method of progeny screening from the seeds obtained from the plant cultivar `Bipuli` (unpatented) of Pelargonium graveolens, from which a novel, unique and commercially viable plant of rose scented geranium Pelargonium graveolens with high quantity and quality of essential oil yield was screened out. Further, the invention relates to the development of a high essential oil yielding hybrid named as `Safal` through a planned selection and analysis of the `Bipuli` seedling progenies. The essential oil of the plant is rich in rhodinol (89%) which includes the constituents geraniol, citronellyl, geranyl acetate, citronellyl acetate, geranyl formate, citronellyl formate, phenyl ethyl alcohols, cis and trans rose oxides, linalool and likewise. The hybrid of the ...

AI Technical Summary

Benefits of technology

The main object of the present invention is to develop a new and distinct plant of Pelargonium graveolens `Safal`, through progeny screening from the seeds obtained from the plant cultivar `Bipuli` of Pelargonium graveolens, said plant capable of producing higher quantity and quality of essential oil.

Problems solved by technology

Geranium oil is one of the expensive essential oils used in perfumery, cosmetics and soap industries.

The spread of geranium cultivation has been narrow because the prevalent cultivars of Pelargonium graveolens are highly susceptible to water logging in soil, white ants and several bacterial and fungal diseases.

Also there is paucity of genetic resources in Pelargonium species cultivated for essential oils.

The available varieties suffer from high degree of male and female sterility.
