Abstract:

Investigations aiming at genetic improvement in Adenium obesum, a popular flowering pot plant were carried out at Advance Technology Centre of soilless system, department of Floriculture and Landscape Architecture, NAU, Navsari. Hybridization was initiated with ten parents (seven females and three males) in 2014 and their crosses were studied during 2015 to 2016. Among the crosses studied, a germplasm viz., SDSH1 (Sudarshan x Double Sweet Heart) showed novel morphological character for multipetalous form having attractive bright red coloured fifteen petals. This germplasm was further evaluated for stability and other flowering parameters along with its parents viz., Sudarshan and Double Sweet Heart and the local germplasm, Local Pink for two years 2016-17 and 2017-18. The flowers of SDSH1 showed significantly superior flower diameter (7.36 cm) while that of Sudharshan was minimum (5.63 cm) as seen in the pooled data of two years. Diameter of corolla was maximum (1.50 cm) in Local Pink while length of corolla tube (4.08 cm) was maximum in Double Sweet Heart. Further, maximum flower weight (2.75 g) was observed in the SDSH1, followed by Double Sweet Heart (1.76, 1.83 and 1.79 g) as per the pooled data. Number of petals was maximum in the SDSH1which looked showy with triple whorls having fifteen petals, as compared to one parent Double Sweet Heart with ten petals and Sudarsahn and Local Pink with five petals. The germplasm SDSH1 recorded significantly maximum flowers per cluster (8.01) while Local germplasm showed minimum (4.01). In situ flower longevity was observed to be highly significantly maximum in the SDSH1 (20.17 days) followed by Double Sweet Heart (11.00 days). Since, the germplasm SDSH1 was novel in flower morphology having multipetalous flower form in bright red colour and superior in other flowering parameters it was renamed as Gujarat Adenium 1 (G. Ad.1) and released in SVRC, Gujarat.
