Characterization of different tuberose genotypes through DUS testing

Tuberose is commercially significant bulbous ornamental crop, cultivated extensively for its attractive and fragrant cut flowers, as well as loose flower. As there is considerable misunderstanding in the nomenclature of genetic material existing in various Indian states because they are solely referred to as one genotype and all local duplicates are most likely from another. Apart from registration and commercial introduction of new kinds, the main focus at the moment is to maintain their purity. This study aimed to screening and identified the desirable tuberose genotypes from half sib population of ten different tuberose viz. Phule Rajani, Arka Shringar, Arka Sugandhi, Arka Nirantara, GKTC- 4, Hyderabad Single, Sikkim Selection, Bidhan Ujjawal, Bidhan Jyoti, Mexican Single. Among the population significant genetic diversity and variability were recorded morphological, flowering and yield parameters. However, distinct differences were noticed in floral and vegetative traits in half-sib genotypes which exhibited diverse characteristics, including yellow and pink flower colors, as well as semi-double and double florets.
