    Morphological characterisation of tuberose (Polianthes tuberosa L.) genotypes under Punjab conditions
    (Punjab Agricultural University, Ludhiana, 2017) Manpreet Kaur; Madhu Bala
    The aim of this study was to evaluate the tuberose (Polianthes tuberosa L.) genotypes collected from different regions of India under Punjab conditions. The experiment was conducted at the Research Farm, Department of Floriculture and Landscaping, PAU Ludhiana during 2016-2017. The experiment consisted of total eight single type cultivars of tuberose namely Local Single, Prajwal, Shringar, Mexican Single, Sikkim Selection, Calcutta Single, Phule Rajni and Pune Local Single were evaluated on the basis of their different growth and yield parameters. Among these cultivars evaluated, ‘Prajwal’ took minimum days for spike emergence (81.73 days), minimum days for opening of first floret (114.33 days), exhibited maximum plant height (54.53cm),spike length (90.53 cm) rachis length (42.00 cm),number of spikes per clump (4.80) and duration of flowering (34.27 days).Number of floret per spike and length of floret was recorded maximum in ‘Calcutta Single’ (46.60) which was at par with ‘Prajwal’ (45.93) and ‘Prajwal’(5.85 cm) was at par with ‘Calcutta Single’(5.78 cm) respectively. ‘Prajwal’ is also a good multiplier and produced significantly more bulbs and bulblets (2.93 and 18.40) respectively in comparison to the other cultivars whereas minimum bulbs and bulbets was recorded in cv. ‘Mexican Single’. From the above study it can be concluded that among all the single tuberose cultivars, ‘Prajwal’ performed best in all the growth, flowering and yield parameters under Punjab conditions.
