ABSTRACT
The present investigation entitled, “Evaluation of Bellis perennis L. cultivars under different altitudinal gradients
in Himachal Pradesh” was carried out at three locations based on altitudinal gradients viz. AG- 1 i.e. Regional
Horticultural Research and Training Station, Dhaulakuan (468 m amsl) , AG – 2 i.e. Experimetal Farm at Khaltoo,
Department of Seed Science and Technology of Dr. YS Parmar University of Horticulture and Forestry, Nauni (1060 m
amsl) and AG – 3 i.e. Experimental Farm, Department of Floriculture and Landscape Architecture of Dr. YS Parmar
University of Horticulture and Forestry, Nauni (1276 m amsl) by growing six cultivars of English daisy namely ‘Single
Meadow’, ‘Monstrosa Double White’, ‘Monstrosa Double Mix’, ‘Pomponette Rose’, ‘Pomponette Red’ and ‘Pomponette
Mix’ during 2020-21. The experiment was laid out in RBD (factorial) with 18 treatment combinations replicated thrice.
Among different altitudinal gradients, Dhaulakuan farm (AG -1) gave best results for plant growth, flowering, seed yield and
seed quality parameters while, altitudinal gradient of floriculture farm (i.e. AG – 3) exhibited maximum duration of
flowering. Among different cultivars, the plants of cv. ‘Pomponette Red’ took minimum days for first flowering and showed
maximum duration of flowering. However, minimum time for full blooming was taken by the plants of cv. ‘Single
Meadow’. This cultivar also registered maximum values for plant height, number of flower heads per plant, number of
seeded heads per plant, seed yield per plant as well as seed yield per plot and per hectare too. Whereas, cv. ‘Monstrosa
Double White’ exhibited superior results w.r.t. flower head diameter, number of seeds per head, seed germination, seedling
length, seedling dry weight, seed vigour index-I and seed vigour index-II. Among the interactions, best results for plant
growth, flowering and seed yield parameters were obtained in AG-1 × C1 i.e. growing of cv. ‘Single Meadow’ at altitudinal
gradient of Dhaulakuan farm. While, better seed quality was observed in the interaction, AG-1× C2 i.e. growing of cv.
‘Monstrosa Double White’ at altitudinal gradient of Dhaulakuan farm and closely followed by the interaction, AG-1× C3 i.e.
growing of cv. ‘Monstrosa Double Mix’ at altitudinal gradient of Dhaulakuan farm. From the present study, it is concluded
that among different altitudinal gradients, superior results for plant growth, flowering, seed yield and seed quality were
obtained at altitudinal gradient of Dhaulakuan farm (468 m amsl). Among different cultivars evaluated, best performance
was exhibited by cv. ‘Single Meadow’ w.r.t. various growth, flowering and seed yield parameters. However, best seed
quality was found in cv. ‘Monstrosa Double White’ followed by cv. ‘Monstrosa Double Mix’.
