Germplasm characterization of chrysanthemum (Dendranthema grandiflora Tzvelev) genotypes under Bihar conditions

Abstract

Twenty chrysanthemum genotypes were evaluated under Bihar conditions during the year 2020-21 to identify suitable varieties for commercial flower production. Genotype namely Achievement, Alfred Simpson, Beautica Marry, Bolare Deo, Coronation Gold, Coronation Pink, Cassandra, Pompon Rosy Pink, Crimson Pretty Pottey, Crimson Crystal, Crimson Title, Dignity, Dorridge Queen, Duke of Kent, Frosty Whisker, Mahatma Gandhi, Miss India, Red Wine, Royal Prince and S.L. Andre were selected for six vegetative and six floral traits. This experiment was laid out in Completely Randomized Design (CRD) with three replications. Significant differences were recorded among different genotypes for various growth and flowering attributes. Genotype Pompon Rosy Pink recorded maximum plant spread (42.72 cm), whereas maximum plant height at harvesting stage (104.03 cm) was reported in genotype Miss India. Maximum number of secondary branches per plant (120.68) was recorded in genotype Duke of Kent, while genotypes Bolare Deo attained early reproductive stage in 64.35 days. Genotype Red Wine reported maximum leaf biomass (775.40 g), days taken for full blooming (168.02 days) and flower longevity (20.02 days), while genotype Crimson Pretty Pottey obtained maximum flower duration (41.27 days). Genotype S.L. Andre produced maximum flower diameter (18.64 cm), Beautica Marry yielded maximum number of ray florets (446.33) and Achievement recorded maximum flower yield per plant (746.31 g).
