Abstract
The present investigation was carried out at Floriculture and Landscaping Block, College of
Horticulture, VCSG, UUHF, Bharsar, Pauri Gharwal (Uttarakhand) during the year 2016-2017, with 15
genotypes in the Randomized Block Design, with three replications. Observation was made for vegetative,
floral, quality and yield parameters. Data were analyzed to study the mean performance, extent of variability,
heritability and character association for different parameters.
Results revealed that among the vegetative characters, genotype Punjab Anuradha recorded maximum
plant height (79.28 cm), plant spread (49.44 cm), numbers of primary branches (19.13), secondary branches
(30.13) and number of leaves per plant (373.04), Genotype White star recorded highest leaf area (23.98 cm2).
Among the floral characters, significant variations were observed among the genotypes, Genotype Punjab
Anuradha recorded early flower bud initiation (62.13 days), minimum days taken for 1st harvesting (88.89
days), whereas genotype Dolly white recorded minimum days taken for 50% flowering (89.21 days), Genotype
Ajay recorded minimum days taken for 100% flowering (101.80 days) and the genotype White Bouquet had
longest duration of flowering (62.61 days). In case of yield and quality parameters, Genotype White star
recorded highest yield per plant (10.56 kg) and highest flower weight (7.47 gm), with maximum vase life (19.67
days) and shelf life (10 days).
Genetic analysis indicated that phenotypic coefficient of variation (PCV) was higher than genotypic
coefficient of variation (GCV) in all of the attributes studied. The phenotypic and genotypic coefficients of
variation were found highest for yield per plot (kg), weight of flower (gm), number of flowers per plant, stalk
length (cm), number of secondary branches and shelf life (days). Highest heritability coupled with highest
genetic advance was seen in number of leaves per plant, whereas, highest heritability coupled with genetic gain
was seen in weight of flower (g). In genotypic and phenotypic correlation, significantly positive correlation was
found with plant height (cm), plant spread (cm), number of primary branch, number of secondary branch,
number of leaves per plant, leaf area (cm2) and number of flower per plant, whereas, in genotypic and
phenotypic path coefficient analysis, it is found that number of leaves per plant has direct positive effect on
yield per plot.
Thus, from the present investigation it can be concluded that out of 15 genotypes, Punjab Anuradha,
White Star, Pusa Centenary and White Bouquet were found highly suitable for commercial cultivation under the
hilly regions of Uttarakhand.
