Abstract
The investigation was carried out to estimate direct and indirect selection of flower yield in 'damask rose', (Rosa damascena (Mill). The selection ga in for flower yield was 19.97 per cent while among component traits it was maximum for plant spread (27.85%) followed by flower/plant (16.80) and bran ches/plant (13.80%). The correlated response in flower yield was highest th rough flowers/plant (35.69), branches/plant (28.80) and flowers/raceme (18. 49). Relative selection efficiency (RSE) was more than unity and in proport ion to correlated response (CRY) for these 3 traits, indicating the role of these traits in multiple selection index to enhance flower yield.
