Abstract and Figures

The precise knowledge of the environmental influence on the growth and development of any crop is crucial in order to understand the suitability of any cultivar for commercial cultivation in a particular region. The present study investigated the estimation of the genetic variability, heritability, genetic advance (GA), genetic gain and correlation among 38 tulip genotypes. The study was undertaken at the experimental farm of the Department of Floriculture and Landscape Architecture, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP, India) from 2018 to 2020 with the objective to evaluate the performance of different genotypes of tulip under mid-hills of Himachal Pradesh. The findings revealed that high genotypic coefficient of variance (GCV) was recorded for flower size, number of bulbs/plant, scape length, plant height, bulb weight, leaf area, days to sprouting and duration of flowering. Character such as plant height, scape length, duration of flowering and days to flower opening recorded high heritability coupled with moderate GA. Scape length, plant height, flower size, number of leaves/plant, bulb weight, leaf area, days to sprouting, flowering duration, vase life and bud length recorded high heritability and highest genetic gain. Significant positive correlation was recorded for plant height, leaf area, bud length and vase life etc. Maximum positive direct effect of flowering duration, vase life, days to flower opening, plant height, number of bulbs/plant and weight of bulblets/plant etc., on the weight of bulbs/plant revealed the true relationship between them, thus suggesting that these traits should be considered in selection programme.

Abstract The precise knowledge of the environ-
mental influence on the growth and development of
any crop is crucial in order to understand the suit-
ability of any cultivar for commercial cultivation in
a particular region. The present study investigated
the estimation of the genetic variability, heritability,
genetic advance (GA), genetic gain and correlation
among 38 tulip genotypes. The study was undertaken
at the experimental farm of the Department of Flo-
riculture and Landscape Architecture, Dr. YS Parmar
University of Horticulture and Forestry, Nauni, Solan
(HP, India) from 2018 to 2020 with the objective to
evaluate the performance of different genotypes of
tulip under mid-hills of Himachal Pradesh. The find-
ings revealed that high genotypic coefficient of vari-
ance (GCV) was recorded for flower size, number of
bulbs/plant, scape length, plant height, bulb weight,
leaf area, days to sprouting and duration of flowering.
Character such as plant height, scape length, duration
of flowering and days to flower opening recorded high
heritability coupled with moderate GA. Scape length,
plant height, flower size, number of leaves/plant, bulb
weight, leaf area, days to sprouting, flowering dura-
tion, vase life andbud length recorded high herit-
ability and highest genetic gain. Significant positive
correlation was recorded for plant height, leaf area,
bud length and vase life etc. Maximum positive direct

The present investigation entitled “Variability and association studies among mutants of carnation (Dianthus caryophllyus L.) in Northwestern Himalayas” was carried out at the experimental farm of the Department of Floriculture and Landscape Architecture, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2019 to 2020. Twenty diverse genotypes of carnation (Dianthus caryophyllus L.) including 15 mutants, 4 parents (Dark Rendezvous, Madras, Raggio de Sole and Tempo) and check (Gaudina) were evaluated to assess the extent of variability, heritability, genetic advance, genetic gain and correlation between different characters. A high phenotypic and genotypic coefficient of variation was recorded for calyx splitting followed by the number of petals per flower. High heritability coupled with high genetic advance was recorded in the character number of petals per flower. High heritability coupled with a high genetic gain was recorded for characters like; calyx splitting, the number of petals per flower, vase life, duration of flowering, stem length and thickness of flower stem. Whereas, characters like number of marketable flowers per meter square, flower size, number of marketable flowers per plant and days taken for harvesting of cut stems recorded high heritability coupled with moderate genetic gain indicating selection of these characteristics for improvement. The significant positive correlation coefficient for the number of marketable flowers per plant was observed with the number of marketable flowers per meter square, vase life, bud length, thickness of flower stem and duration of flowering at both phenotypic and genotypic levels. Maximum positive direct effects cited towards the number of marketable flowers per plant were contributed by flower size followed by number of marketable flowers per meter square, plant height, duration of flowering, vase life, number of petals per flower and bud length. The direct selection of these characters will be fruitful for increasing flower yield.

Genetic variability and correlation studies among different Lilium genotypes
Article
Full-text available
  • Sep 2020
The present study was carried out for two years (2016-18) to estimate the genetic variability, heritability, genetic advance, genetic gain and correlation among 18 Lilium genotypes. Findings revealed characters such as number of bulblet/plant, number of leaves/plant and number of flowers/plant recorded high genotypic coefficient of variability (GCV). High heritability coupled with moderate genetic advance recorded for number of leaves/plant, plant height and stem length. Moderate heritability with highest genetic gain recorded for number of bulblets/plant followed by traits such as number of leaves per plant, leaf width, number of flowers/plant and weight of bulblet etc. Significant positive correlation of yield parameter (number of flowers per plant) recorded with plant height, number of leaves per plant, leaf length, stem length, stem diameter, duration of flowering, bulb diameter and weight of bulb etc. Maximum positive direct effect of days to flower bud formation, number of leaves per plant, bulb diameter, weight of bulb, leaf length, stem length etc. on number of flowers per plant revealed the true relationship between them and selection on the basis of these characters would be more effective for the improvement among Lilium genotypes.

Identification of Superior Carnation (Dianthus caryophyllus L.) Cultivars Based on Morphological Traits
Article
Full-text available
  • Oct 2022
Flowering industry is now expanded rapidly and requires the introduction of new cultivars to the market of plants. The introduction of new cultivars has an extensive and difficult process, so that the potential of cultivars in different areas has to be identified, and then, the selection of varieties to be made. The present study was undertaken to determine the morphological diversity among the 12 varieties of carnation cultivated in the commercial greenhouse. The characteristics related to growth, flowering, quality, and yield were measured. The qualitative characters including the leaf color, fusarium wilt, petal density, and fragrance were measured based on the rating and coding. The Cream Viana, Noblesse Vilesse, and Orange Viana have emerged as promising cultivars with respect to flower yield and vase life. In addition, regarding the important characters of carnation such as the problems of calyx splitting and flower fragrance, the Nautilus cultivar was promising and might be cultivated in greenhouse and also could be used as a parent in the breeding programs. The correlation studies revealed that the flower yield has an inter-dependent relationship with the vegetative parameters like number of nodes, length and width of leaves, and diameter of stem. In addition, the vase life has a direct relationship with the morphological flowering traits such as flower diameter, length, width and number of petals. Hence, the selection of the above-mentioned stable characters in the promising cultivars will be helpful in improving the flower yield, and these characters could be beneficial in the breeding programs.

Morpho-metric characterization and genetic variability studies in chrysanthemum
Article
  • Feb 2022
Germplasm characterization is essential to estimate variation and identify desirable genotypes for crop improvement. The current study was conducted on eight qualitative and 14 quantitative traits related to growth and floral attributes for characterization and grouping of 54 chrysanthemum genotypes. Wide variability was observed among most of the traits and principal component analysis revealed that the first two principal components explained most of the existing variation (>98%) in germplasm. Genotypic coefficient of variation exhibited a wide range from 9.41% (ratio of leaf length/width) to 105.99% (corolla tube length of ray florets), while phenotypic coefficient of variation varied from 10.49% (ratio of leaf length/width) to 106.38% (corolla tube length of ray florets). Broad sense heritability estimates were higher (>96%) for most of the characters, except for traits such as ratio of leaf length/width and peduncle thickness. Forty-four pair-wise inter-trait combinations showed positive genotypic and phenotypic correlations for 91 possible combinations. D ² analysis revealed that genotypes of clusters I and IV to be highly distinct, and hybridization between them might have better chance to obtain desirable types. D ² analysis confirmed that the cultivars in cluster IV namely, Red D Spoon, Tokyo Soldier, Yellow Reflex and hierarchical clustering showed that the cultivar Tokyo Soldier to be highly diverse. It is recommended to use the above genotypes in crossing programme for obtaining better progenies.
