SCREENING OF SUITABLE GERMPLASM OF TUBEROSE (POLIANTHES TUBEROSE L.) FOR MID HILL CONDITIONS OF GARHWAL HIMALAYAS
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
Ten Tuberose (Polianthes tuberosa L.) genotypes were assessed for their performance under mid hill conditions of Garhwal Himalayas during 2015. Uniform healthy bulbs were planted at a spacing of 30cm × 20cm in randomized complete block design with three replications. Significant differences were obtained among the genotypes for all vegetative and floral characters studied. The minimum days taken for bulb sprouting (28.66) and maximum yield of florets (2.00 kg) were found in Hyderabad Double. The maximum plant height (42.55 cm) was observed in Hybrid -1 whereas; the higher plant spread (45.20 cm) was observed from Maxima Single genotype. Shringar genotype was recorded to have maximum number of leaves (58.30) and vase life (10.20 days). Prajwal genotype recorded maximum leaf area (38.19 sq.cm), number of spike per plant (3.93), number of spike per m2 (25.66), number of florets per spike (35.53) and spike weight (97.25 g) with minimum days taken to spike emergence (60.00). However, maximum floret diameter (4.35 cm) and flowering duration (11.73 days) were found in genotype Vaibhav and maximum (77.63 cm) length of spike in Sikkim Selection.
