Abstract
Investigations are carried out during 2013-14 to 2014-15 at experimental unit of Department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere (University of Agricultural and Horticultural Sciences, Shivamogga), to assess the genetic variability of Asiatic Lily through morphological and molecular markers, to develop and study the performance of F1 hybrids, to standardize the dates of planting and NPK nutrition along with study on the effect of chemical preservatives on vase life of cut-flowers. Fifteen genotypes were evaluated for morphological and molecular characters which were grown under protected condition. The genotype Mestre recorded maximum plant height (90.53 cm) as compared to other genotypes and was found to be on par with Pavia. The genotypes Pirandeu, CEB Dazzle, Dazzle, Courier, Pavia and Tresor were found to be and recorded maximum number of spikes per square meter (24.00) while, the genotype Batistero recorded the minimum number (16.67). Cluster analysis through SRAP (Sequence Related Amplified Polymorphism) markers, showed that groupings of the genotypes based on colour ranges. Thirteen genotypes were grouped together to form a major cluster and the second major cluster constituted two genotypes viz., Telisker and Merluza. There were 15 F1 combinations produced and all the offspring’s were superior to their parents with respect to morphological parameter and yield. Among different dates of planting in Asiatic lily cv. Pavia, the maximum plant height (55.73 cm) and stalk length (52.67 cm) was observed in October month of planting followed by November month planting. The maximum plant height (60.84 cm), leaf area (11.62 cm2), leaf area index (23.25) and number of spikes per square meter (18.67) recorded in the treatment which received NPK @ 20, 20, 20 g/m2. The maximum vase life (13.17 days) was recorded in vase solution containing 1-Mehtyl Cyclo Propane (MCP) @ 1000 nl/l + Sucrose 2 per cent.
