Stability analysis of carnation (Dianthus caryophyllus) varieties using stability models

Abstract

In this paper, an attempt was made find the stable variety of carnation using stability models. For this purpose, data on eight parameters viz plant height(m), stem length(m), number of days to flower bud formation, number of days for first flowering, flower size(cm), number of flower stem per plant, Duration of flowering(days) and vase life(days) of 50 varieties for three flushes were collected during 2016-2017. Discriminant analysis was performed to group the varieties into higher and lower yielder varieties. The higher yielder group was subjected to the stability analysis. Varieties Master and Rendez Vous were found to be most stable for number of days for first flowering, pink dover and UHFSCar Col.-13 for number of flower per stem, UHFSCar Col.-5, UHFSCar Col.-10, UHFSCar Col.-18 and UHFSCar Col.-19 for flower size, rendez vous, UHFSCar Col.-13 and UHFSCar Col.-19 for duration of flowering.
