Performance of Tuberose (Polianthes tuberosa L.) Genotypes for Growth, Flower Yield and Bulb Production under Konkan Conditions

Abstract

A field experiment was carried out during 2024–2025 at the Hi-tech Nursery block of Floriculture, College of Horticulture, Dapoli, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Dist. Ratnagiri (Maharashtra), to evaluate the Performance of tuberose (Polianthes tuberosa L.) genotypes for growth, flower yield and bulb production under Konkan conditions. The experiment was laid out in a Randomized Block Design (RBD) with four replications, comprising nine genotypes: Local Single, Arka Shringar, Phule Rajani, Local Varigated, GK- T-S-1, Prajwal, Phule Rajat, Arka Vaibhav, and Arka Suvasini. The results indicated significant variation among the genotypes with respect to various growth, flowering, and bulb production parameters. Among the evaluated genotypes, GK-T-S-1 exhibited superior performance and recorded the highest values for plant height (86.03 cm), number of leaves (42.00), leaf area (75.54 cm2), leaf area index (1.98), dry matter of leaves (16.67 g), maximum spike length (119.97 cm), number of florets per spike (42.45), rachis length (49.12 cm), number of spikes per plant (3.05), spikes per plot (37.00), yield of flowers per plot ( 2.24 kg) and per hectare (116.88 q/ha), bulb yield per plant (3.10), bulb yield per plot (3.31 kg), bulb yield per hectare (172.44 q/ha) and diameter of bulb (67.90 mm) On the other hand, the genotype Prajwal recorded maximum dry matter of spike (13.51 g), diameter of flower stalk (5.55 mm) and flower length (6.83).
