Performance of different cultivars of Dahlia (Dahlia variabilis L.) under agro-climatic conditions of Gwalior

Abstract

The present investigation entitled “Performance of different cultivars of Dahlia (Dahlia variabilis L.) Under agro-climatic conditions of Gwalior” was carried out in the Research field of Department of Horticulture, School of Agriculture, ITM University Gwalior during the year 2014-2015. The experiment was laid out in randomized block design with three replications and 12 treatments V1- Kenya Red, V2- Blackout, V3- Jyotsana,V4 - DRS,V5 - Korean Orange, V6 - CalvinRose, V7 - Korean Yellow, V8-Prime Minister, V9-Kenya Gerua, V10-Kenya White, V11 - Korean Blue, V12- Korean White. Study shows that the cultivar Prime Minister recorded maximum plant height (23.54 cm), number of leaves (59.57), number of branches (6.34) and number of flowers per plant (8.31). Minimum number of days taken to flowering was recorded in Blackout (56.39). Maximum diameter of flower (19.68 cm) and maximum bloom life of flower was recorded in Korean Orange (8.28). Further, the maximum numbers of tubers has been recorded Prime Minister (7.55) whereas; maximum weight of the tuber (85.32g) was recorded in Korean Orange. Thus, it was concluded that the cultivar Prime Minister is most suitable cultivar of Dahlia to get maximum number of flowers and tubers whereas, the cultivar Korean Orange was found to be best for flower diameter, bloom life of flowers and weight of tubers under Gwalior agro-climatic condition.
