Abstract:

An experiment was conducted with 32 cultivars of dahlia (Dahlia variabilis L.) to study correlation and path analysis among the yield attributing traits and their effect. Correlation among component characters showed that flower yield per plant had a highly significant positive genotypic correlation with leaf area index (0.617), crop duration (0.771), flowering duration (0.800), tuber weight (0.668) and change in fresh weight at day 3. Path-coefficient analysis revealed a positive direct effect of duration of crop, duration of flowering, flower diameter, vase life, total chlorophyll content and change in fresh weight at day 3 on flower yield per plant proving that direct selection of these traits can be implemented for yield improvement. Hence the parameters selected in the study are sufficient for direct selection of cultivars for cut flower attributing traits in dahlia.
