Benefits of technology
The 'CIMAP-KHUSINOLIKA' clone significantly reduces crop gestation period to six months, achieving higher Khusinol content and oil yield, making it suitable for commercial cultivation and integration into existing cropping systems, while maintaining essential oil quality and stability.
Problems solved by technology
However, its long duration (18 months) and poor root yields, variable oil content and quality and Khusinol (a desirable oxygenated sesquiterpine likened to Khusimol for its vetiverol characteristics) content just up to 10%, have hindered its acceptance among the farmers and perfume industry.
Extensive breeding efforts have been undertaken at various research centre in India to develop / identify suitable clones to produce homogenous population and uniform quality for its essential oil under vetiver cultivation (for details see Lavania 2008 for an overview), but the problem of long gestation period for crop under cultivation and quality of root-essential oil has long bothered the scientists.
Isolation of this sesquiterpenoid from a complex blend of vetiver essential oil is difficult.

Breeding History
[0016]Looking into the commercial importance of the vetiver oil obtainable from the roots of vetiver, extensive efforts have been made in India to develop improved varieties and clones in this essential oil crop (for an overview—see Lavania 2008). However, none led to the realization of a short duration plant type that could produce essential oil of superior quality. The development of the present clone fills this gap.
Method of Development of the Plant Clone ‘CIMAP-KHUSINOLIKA’
[0017]India is the centre of diversity of vetiver. Plant grows wild throughout India, more particularly in peninsular India and plains of central and northern India. In the north Indian state of Uttar Pradesh its occurrence is quite profuse and huge amount of variation is noticeable in the wild populations. Therefore, an extensive population improvement programme was started to identify a genotype that could be suitable for cultivation under short duration fitting in cropping systems for produc...

The present invention relates to the development of a novel, morphologically and genetically distinct khusinol rich essential oil producing clone of vetiver [Vetiveria zizaniodes (L.) Nash. syn. Chrysopogon zizanioides (L.) Roberty; family Poacaeae} named ‘CIMAP-Khusinolika’. The plant of this clone is characterized by spreading type clump canopy in the initial stage, white feathery stigma and capable of producing >1% (v / w) essential oil containing 45-50% Khusinol (v / v) obtained after hydro-distillation from fresh roots harvested from 6 month old plantations. This clone has unique ISSR profiles that serve as DNA-fingerprints. The clone was obtained through recurrent selection in polycrossed population generated from the bulk of wild collection, and can be propagated through vegetative slips (3 to 6 month old stem with few roots) for commercial plantation as a short duration crop.
Description
[0001]Latin name of the genus and species claimed: Vetiveria (syn. Chrysopogon) Species: zizanioides. [0002]Variety denomination: ‘CIMAP-KHUSINOLIKA’.FIELD OF THE INVENTION[0003]The present invention is related to the development of a novel, distinct, khusinol rich, short duration, spread clump behavior plant type (clone) of vetiver (Chrysopogon zizanioides) obtained through recurrent selection in polycrossed population generated from the bulk of wild collections, Vetiver plant named ‘CIMAP-KHUSINOLIKA’ with the Latin name Chrysopogon zizaniodes, and the varietal denomination of ‘CIMAP-KHUSINOLIKA’. The mass propagation of this clone is through vegetative multiplication using slips (3 to 6 month old stem with few roots), and hence this plant is genetically uniform and stable. This has unique spread clump growth behavior, not observed in other varieties and genotypes. The clone holds commercial advantage since the plant roots of desirable quality can be harvested after 6 months that ...
