Study on Genotypic Correlation Coefficient in Dahlia Germplasm

Dahlia is an important bulbous flower crop which has position to increase economic earnings of growers. Forty varieties were grown and studied for genotypic correlation of 16 traits at C.S. Azad University of Agriculture and Technology, Kanpur during 2011-12 and 2012-13. Vegetative and reproductive characters were found to have considerable relationship which also indicated the scope for making improvement in dahlia. Plant height and maximum number of flower per head revealed the sustainable magnitude for crop improvement in dahlia crop.
