Identification of genotypes better suited for particular region and their improvement is of immediate task to exploit their full potential. The improvement can be brought out after confirming the association among the most important growth with quality attributes. Hence, varietal evaluation becomes necessary to find out suitable variety for a particular region. Experiment was conducted with 20 different decorative types of dahlia varieties at Jambuvadi Farm, College of Horticulture, Junagadh Agricultural University, Junagadh which falls under South Saurashtra Agro-climatic Zone during 2021-22. The analysis of variance revealed significant differences among the genotypes for eleven characters in dahlia viz., plant height, number of leaves per plant, number of branches per plant, stem girth, days taken to first bud initiation, diameter of flower, stalk length, vase life, anthocyanin content, chlorophyll content and flower yield which indicated the existence of variability in the experimental material. The estimates of genotypic (σ2g) and phenotypic variances (σ2p) of each character were carried out.

Genetic variability existing among genotypes is the prime and basic factor for the improvementof any character in a successful breeding programme of tuberose (Polianthes tuberosa L.).Though the attempts made so far to exploit the available variability have culminated in therelease of a few improved region specific selections as varieties from different centers inIndia, still, varieties suited to coastal eco-system are yet to be identified. Hence, an experimentwas laid out to study the performance of 21 genotypes of Polianthes tuberosa L. collected fromvaried geographical locations. The trial was conducted in the floriculture unit of the Departmentof Horticulture, Faculty of Agriculture, Annamalai University under randomized block designreplicated thrice to assess the genetic variability for eleven economic characters. The resultsshowed that the genotype PT-15 recorded relatively superior mean performance with respectto all characters. High PCV and GCV were observed for number of leaves per plant, plantheight and rachis length. Low variability in terms of PCV and GCV was observed for length ofthe flower and time taken for flowering. High PCV and GCV values of more than 60 per centwas observed for bulb volume followed by yield of flowers per plant, rachis length and durationof flowering. The genotypes viz., PT-15 (Kuzhumani, Thiruchirappalli District), PT-3(Ravanthavadi, Dharmapuri District) and PT-10(Perumalpatti, Dindugul District) were identifiedas superior genotypes which are suitable for the coastal region based on per se values and canbe utilized for future breeding programmes.
