Appraisal's genotypes on water absorption, transpiration loss at senescence stage and genetic correlation of Chrysanthemum morifolium

Abstract

A field experiment entitled “Appraisal's genotypes on water absorption, transpiration loss at senescence stage and genetic correlation of Chrysanthemum morifolium” was conducted at experimental orchard, department of Horticulture, CCS Haryana Agricultural University, Hisar (Haryana) during the 2016-17 in winter season to  identify the suitable variety for successful cultivation as well as vase life of Chrysanthemum flower. Fifteen Genotypes namely, Aparajita, Anastasia, Braca Splendid, Charlia, Celtic, Cologne, Fortune, HF-164, Paladov Sunny, Paiwer-W, Paladov Dark, Papaya, Tocovar- 6, Vanilla Sorbet and White Double were selected for the  evaluation. The significant responses in water absorption, transpiration loss at senescence stage and flower vase life were observed in White Double, Cologne, Charlia and Celtic. The maximum water absorption and transpiration loss were recorded in genotype White Double (116.83g and 72.20 ml. respectively) whereas maximum fresh weight was recorded with the genotype Cologne (120.00 g) while genotype White Double had longest vase life (20.66 days). The maximum per cent of opened flowers were noticed in the genotype Charlia (92.45 %) while maximum unopened flowers were noticed in genotype Celtic (21.86%) and the significant genetic correlation between different parameters and vase life of flowers were noted during experimentation.
