Pooled estimates of mean, genotypic & phenotypic coefficient of variability, heritability, genetic advance and genetic gain among Lilium genotypes
Source publication
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...

... the standard cultural practices were carried out throughout the growing period. Observations were recorded on ten randomly selected plants of each genotype in each replication for 21 quantitative parameters (Table 1 and Table 2). ...Context 2
... variations are not fixable. In our study, high value of PCV (>30%) was recorded for number of bulblets/ plant (61.69%), number of flowers per plant (44.91%), number of leaves/plant (37.82%), weight of bulblet (35.41%) and leaf width (30.39%) (Table 1). Similarly, Kumar (2013) in Lilium, Pratap and Rao (2006), Kumar et al. (2015) in gladiolus andJhon et al. (2006) in tulip also reported higher PCV than GCV for most of the characters. ...Similar publications
Sweet stalk sorghum has been the subject of very few investigations in Burkina Faso. This study aimed to evaluate the variability of agro-morphological traits and to estimate genetic parameters as well as the correlations between quantitative traits in order to identify appropriate breeding strategies. Eighteen traits were evaluated in 29 sweet sor...
The present investigation was conducted to study the correlation coefficient and path coefficient analysis for 12 characters in Augmented Block Design of seventy five genotypes with three checks in fennel (Foeniculum vulgare Mill.) and it was carried out in Rabi season, 2020-21 at ANDUA&T, Kumarganj, Ayodhya. Correlation studies revealed that the m...

Similar results were reported in other crops also viz. carnation (Sharma et al. 2023;Taghizadeh and Khadivi 2023), chrysanthemum (Kumar et al. 2021), lily (Kumar 2013;Kumari et al. 2020), gladiolus (Pratap and Rao 2006;Balaram and Jankiram, 2009;Choudhary et al. 2012;Kumar et al. 2015). Further, high estimates of heritability were obtained for all the characters except number of bulblets/plant (39.82%) and weight of bulblets (30.24%). ...
... Further, high estimates of heritability were obtained for all the characters except number of bulblets/plant (39.82%) and weight of bulblets (30.24%). Similar results were reported by Jhon et al. (2006) in tulip and Kumari et al. (2020) in lily. High heritability estimates along with high genetic advance as per cent of mean will be more useful than heritability alone to know the ultimate effect of selection. ...
... The data revealed that weight of bulbs/plant recorded significant positive correlation with bud length (0.417), plant height (0.315), vase life (0.291) and leaf area (0.188) indicating that selection of these traits would also lead to improvement in weight of bulb. Kumari et al. (2020) in lily also observed that positive correlations ensure simultaneous improvement in one or more variables. Scape length revealed a highly significant and positive correlation with the weight of bulbs/plant. ...
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.
