Abstract:
Ten varieties & genotypes have been collected from different sources and evaluated at Instructional farm, Dept. of Floriculture & Landscape Architecture, College of Horticulture, Junagadh Agricultural University, Junagadh during the year 2020-21 to assess the genotypic and phenotypic variability in tuberose. The present study revealed that, among the characters studied, the highest phenotypic range (1.16-2.80) was recorded for number of spikes per plant with coefficient of range 41.41% followed by plant height at 150 DAP (31.66-61.40), number of shoots per plant (3.03-5.66) and weight of bulblets per plant (30.00-56.00) with 34.28%; 31.95%;30.26%; and 30.23% coefficient of range respectively. The number of spikes per plant, the height of the plant at 120 DAP, spike weight, plant height at 150 DAP, and the weight of bulblets per plant all showed high genotypic and phenotypic coefficients of variation, indicating broad variety for these features. For spike weight, number of bulbs per plant, plant height at 150 DAP, and number of spikes per plant, high estimates of broad-sense heritability and genetic progress as a percentage of the mean were found.
