Abstract

An experiment was laid out in a Randomized Block Design (RBD) with three replications to determine genetic parameters and performance of single tuberose cultivars such as “Calcutta Single, Hyderabad Single, Kahikuchi Single, Mexican Single, Navs.ari Local, Phule Rajani, Prajwal, Pune Single, Shringar and Variegated Single” under Coimbatore, India, conditions during 2011-2012. The results of the experiment revealed that ‘Prajwal’ performed best in certain parameters including days to bulb sprouting, weight of bulb, weight of bulblets per clump, number of leaves per plant, days to spike emergence, flowering duration, spike length, rachis length, number of florets per spike, length of the floret, weight of florets per spike, number of spikes/m2 and yield of florets per plot (2 * 2 m). The parameters including flowering duration, weight of florets per spike and number of florets per spike showed high phenotypic and genotypic coefficients of variation. Further, a high heritability coupled with high genetic advance as per cent of mean were observed for flowering duration, weight of florets per spike, number of florets per spike and rachis length.
