Abstract:

An experiment was laid out in a randomized block design (RBD) with three replications to evaluate the performance of ten single tuberose genotypes viz., Calcutta Single, Hyderabad Single, Kahikuchi Single, Mexican Single, Navsari Local, Phule Rajani, Prajwal, Pune Single, Shringar and Variegated Single under Coimbatore conditions during 2011-2012. The results of the experiment revealed that Prajwal showed its superiority for certain parameters viz., days taken for sprouting of bulb, 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 viz., flowering duration, weight of florets per spike and number of florets per spike recorded high phenotypic and genotypic coefficient of variation. Further, high heritability coupled with high genetic advance as per cent of mean was observed for flowering duration, weight of florets per spike, number of florets per spike and rachis length.
