Genetic variability of tuberose mutants with regard to sprouting of bulbs and vegetative growth parameters in the VM2 generation

Abstract

An experiment was carried out to study the distinctiveness, uniformity and stability of traits in the γ-ray irradiated (20 Gy) variants of mutant population of tuberose cv. ‘Hyderabad Single’ in the second generation. Results indicated that untreated control bulbs recorded significantly early sprouting of bulbs (15.50 days) and the plants recorded significantly highest plant height (51.75 cm), leaf width (2.05 cm), leaf length (50.50 cm), plant spread (47.60 cm) and maximum number of tillers (20.50) produced per clump in comparison to 44 variants of mutant population obtained by irradiation of bulbs of cv. ‘Hyderabad Single’.
