Unveiling the Spectacular Performance of Diverse Chrysanthemum Varieties in Flowering, Quality and Yield

Abstract

A comprehensive research initiative conducted in Jhalawar 2019-20 focused on evaluating the genetic diversity and performance of various chrysanthemum varieties. The aim of this study was to evaluate the genetic variability and assess the varietal performance of chrysanthemum (Dendranthema grandiflora Tzvelev) under the specific agro-climatic conditions of Jhalawar. The study sought to identify high-performing varieties and quantify key genetic traits relevant to yield and quality characteristics, with the goal of supporting selection efforts for enhanced chrysanthemum production in the region. This investigation was conducted at the Floriculture and Landscaping block of the College of Horticulture and Forestry, Jhalawar, Rajasthan. The experimental work was carried out during the winter season of the year 2019-20, capitalizing on the local climate to evaluate varietal responses under Jhalawar conditions. The experiment employed a Randomized Block Design (RBD) with multiple replications to ensure robust data. Different chrysanthemum varieties were planted in designated plots, and observations on traits such as flower yield, flower quality, and growth parameters were recorded periodically. Statistical analysis, including ANOVA, was performed to detect significant differences among the varieties. This analysis helped in identifying high-performing varieties suited for Jhalawar conditions and provided insights into genetic variability for potential selection and breeding programs. Ten different genotypes were carefully chosen for the study, including Marigold, Poornima Pink, Dall White, Calcutta Shantini, Karnool, Poornima Red, Dall Yellow, Poornima White, Poornima Yellow and Dundi for in-depth analysis.A randomised block design with three replications was used in the experiment. Cultivar 'Calcutta Shantini' exhibited the maximum days taken to first flower bud emergence of plant (51.50 days) and the maximum number of flowers per plant (269.90). Conversely, cv. 'Dall Yellow' showed the shortest duration to fifty percent flowering (67.64 days). Notably, cv. 'Dundi' displayed the maximum flower diameter (7.47 cm), while cv. 'Poornima Pink' had the longest flower stalk (13.09 cm). Remarkably, cv. 'Marigold' demonstrated the highest flower fresh weight (63.67 gm), dry weight (14.41 gm), and shelf life (4.67 day).
