A population of approximately 50,000 plants raised from mixed stem cuttings collected from perennial rose plantations at the University of Agriculture, Udaipur, Rajasthan, India, and maintained in the field of the CSIR-Institute of Himalayan Bioresource Technology, Palampur, Himachal Pradesh, India, were utilized as an original gene pool of R. damascena. Two varieties, Jwala and Himroz were diversified through selections of desirable traits (morphological/oil content) across 25,000 plants. The five elites, three of R. damascena var. Jwala, (Indica, Super jwala and Jwala) and two of R. damascena var. Himroz (Hot himroz and Himroz) were developed through field selections and maintained at the Natural Plant Products Division Experimental Farm of the Institute. ...

...The experimental material comprised of three parental lines viz. R. damascena cv. Jwala, R. damascena cv. Himroz, R. bourboniana and 68 putative F1 hybrids Jwala x R. bourboniana (11) and Himroz x R. bourboniana (57), maintained in the experimental field of the Institute of Himalayan Bioresource Technology, Palampur, Himachal Pradesh, India. The hybrids were developed by adopting round cut method of emasculation followed by hand pollination (Dhyani et al., 2005) during 2002–2003.

...The Institute of Himalayan Bioresource Technology (IHBT) has developed two varieties of Damask Rose designated JWALA for sub-tropical and HIMROZ for temperate agroclimatic zones. These varieties give consistent flower yield and oil quality in different locations....
(IHBT.Gulab.II) - HIMROZ
This is suitable for cultivation in mild temperature to cold temperate regions (1200-2500 m). Plants are tall, having asymmetric and non-terminal shoot growth with long and thin pedicellate flowers (Fig. 4) borne single or in losse bunch clusters (Fig. 5). Weight of single flower varies from 1.8 to 4.0 gms, and number of petals vary from 25 to 45. It is winter tolerant and grows in temperate areas without any visual sign of winter injury. Flowering period is of 22-25 days which falls during early summer. Flowering time depends on ambient temperature of the location. Loose bunch flowers facilitate easy plucking. It produces consistent flowering shoots in temperate regions and unproductive shoots (upto 65%) if grown under tropical or sub-tropical conditions. Oil content varies from 0.030-0.06%. ....
Oil of JWALA is relatively rich in citronellol than that of HIMROZ though their ratio of citronellol/geraniol remain within the prescribed limits of 1 to 2. Oil of JWALA has lower stereoptanes than HIMROZ. However, there is no major difference in oil quality of rose oil of both the varieties, when grown under recommended conditions. ...
The two varieties when grown in recommended agroclimatic zones give similar flower and oil yields. On an average, flower yield varies from 40 to 45 quintal per hectare, with oil yield of 1.00-1.25 kg. per hectare. As per market rate, pure rose oil is worth Rs. 1.25 to 1.50 lakhs per kg. Fresh rose flowers can be sold @ Rs. 2,000/- per quintal to nearby rose distillers. Dried rose flowers/petals are also sold @ Rs. 10-15 thousand per quintal in specified markets. A net profit of about Rs. 40-50 thousand per hectare can be realised from the cultivation of new Damask Rose varieties. 
Planting material of JWALA and HIMROZ varieties is available with this institute. Planting can be done in monsoon (Jul/Aug) but winter season (Nov/Dec) is preferred. Interested planters can bok their requirement to obtain this on "First come, First serve" basis, on payment.
