Abstract

A new profuse flowering variety G. N. Ad. 4 (Shobhita) derived from a cross of Picottee and Deang Udam Sap was released in adenium, a popular ornamental plant in Gujarat. Research on Adenium obesum, a popular flowering pot plant is being conducted with the basic objective of genetic improvement at Advance Technology Centre of soilless system, department of Floriculture and Landscape Architecture, NAU, Navsari. Hybridization was done involving ten parents (six germplasm as female and three germplasm as male) and their crosses were studied wherein, a cross viz., NAPDUS1 (Picotee × Daeng Udam Sap) showed novel flower trait of profuse flowering habit in cluster with attractive pinkish red coloured petals having sharply pointed tip. Further, NAPDUS1 was evaluated for stability and other flowering characters and tested along with its parents viz., Picotee, Daeng Udam Sap, local germplasm i.e. Local Pink and the earlier released variety, GAd2 as check for three years during 2018to 2020. NAPDUS1 was significantly superior in terms of number of flowers per cluster (10) and maximum number of opened flowers per cluster (8) and number of flowers per plant per year (245) as compared to parents, Local Pink and GAd2 as inferred from the three years mean data. Further, flower clusters per plant and flowering period were also higher in NAPDUS1 as compared to its parents, local pink and check G Ad.2 In view of the fact that the germplasm NAPDUS1 was found to be novel in flower trait bearing profuse flowers in cluster having pinkish red coloured petals with dark red coloured margin and was superior over check GAd2, local Pink as well as it parents, it was renamed as Gujarat Navsari Adenium 4 i.e., G. N. Ad 4 (Shobita) and released in SVRC, Gujarat during 2021

Conclusion

In conclusion, this research endeavour revealed GNAd4 (Shobhita) as a new superior and novel variety in adenium that is developed from a cross of Picottee × Daeng Udam Sap. It bears profuse flowers in clustershaving attractive pinkish-red coloured petals with dark red coloured margins and pointed tips.
