Studies on Association, Path Analysis and Genetic Parameters for Seed Cotton Yield and It’s Contributing Characters in Desi Cotton (Gossypium arboreum L.)

Studies on genetic variability correlation and path analysis in upland cotton

“…The traits like boll weight, seed index, lint index, ginning percentage, 2.5% span length, uniformity ratio, bundle strength and fibre fineness exhibited non-significant association with seed cotton yield. Similar results were reported by Srinivas et al (2015) for ginning percentage and bundle strength; Sunayana et al (2017) for lint index; Rao and Gopinath (2013) for 2.5% span length (mm), bundle strength (g/tex), fibre fineness (µg/inch) and uniformity ratio (%).…”

“…Hence, the selection for these traits will help in selecting genotypes with higher seed cotton yield per plant. Such positive association of seed cotton yield per plant with these traits was also observed by Pujer et al (2014), Asha et al (2015), and Sunayana et al (2017). The close association between yield and yield attributing traits can be exploited in the selection programme which might be helpful in evolving high yielding genotypes.…”

“…al. (2014), Eswari et al (2017) and Sunayana et al (2017) reported high heritability and high genetic advance as percentage of mean for the number of bolls per plant, seed cotton yield per plant revealed the influence of additive gene action for these traits. Hence the improvement of these traits can be made through Computation of correlation between yield and yield attributing traits is of considerable importance in plant selection.…”

“…These findings were also supported by Kulkarni et al, 2011, Pujer et. al., 2014, Sunayana et al, 2017 Gnanasekaran et al (2018) for the number of sympodia per plant; Rama Reddy and Sarma (2014) for boll weight. Heritability estimates along with genetic advance would be more useful in predicting yield under phenotypic selection than heritability estimates alone as suggested by Johnson et al (1955) and Swarup and Chaugale (1962).…”

Study on interplay of yield-related characteristics and fibre quality traits in arboreum cotton (Gossypium arboreum L.)

“…Other traits such as number of sympodia per plant (PCV:15.4, GCV:15.,Shruti et al (2019) andKolhe et al (2022).Heritability in broad sense ranged from 9.27 per cent for uniformity index to 99.44 per cent for number of EJPB https://doi.org/10.37992/2023.1402.064 98%; GAM-18.19). Similar report for lint index was reported byRanjan et al (2014) andKolhe et al (2022) for fibre micronaire. High heritability associated with moderate genetic advance as percent of mean for fibre strength was reported byChaudhari et al (2017),Devidas et al (2017),Joshi and Patil (2018),Kumar et al (2019),Shruti et al (2019),Mankar et al…”
