Abstract

A study was conducted to assess the variability and to establish the correlations among the important quantitative characters in the Hybrid Tea rose under open conditions in hilly regions of Uttarakhand. Five cultivars of HT rose viz., Moonstone (white), Golden Gate (yellow), Cherry Parfait (Pink), Montezuma (Orange) and Bordeaux Red) were used to estimate the magnitude and nature of variation along with finding out correlations among important quantitative traits. It was observed that the estimates of phenotypic coefficient of variation (PCV) were higher than genotypic coefficient of variation (GCV) for all the ten characters under consideration indicating higher degree of environmental analysis. All the quantitative traits had a significant correlation (genotypic and phenotypic) coefficient with flower yield except flower bud diameter. The performance indicated desirable association of flower yield with existing agro-climatic condition of hilly regions of Uttarakhand.
