Abstract
The present experiment was to evaluate eight single petaled tuberose germplasm for growth and flowering attributes. All the tuberose germplasm showed a significant variation in the results. In vegetative parameters, the maximum plant height (79.3 cm) was observed in ‘Mexican Single’, while maximum leaf length (35.1 cm) and leaf width (3.4 cm) was observed in ‘Arka Keerthy’ and ‘Bidhan Rajani’, respectively, then high number of leaves seen in the germplasm ‘Mexican Single. In flowering parameters, ‘Nilakottai local” found superior in days taken for spike emergence (64.7 days), spike length (90.9 cm) and rachis length (31.4 cm) respectively. While, floret length (7.28 cm) and Single floret weight (1.57 g) was observed in ‘Bidhan Rajani’.
