Correlation studies in carnation germplasm

The present investigations were undertaken during 2006–07 and 2007–08 at Model Floriculture Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Uttarakhand on carnation genotypes. Sixteen carnation genotypes were planted in completely randomized block design under low cost polyhouse. The correlation studies revealed that number of flowers per square meter had highly significant and positive correlation with flower diameter (cm), flower duration and leaf pair/stem while flower yield/m² had negative and significant correlation with per cent incidence of disease and incidence of insect pests damage at both genotypic as well as phenotypic levels.
