Stability for Yield and its Component Traits in Groundnut (Arachis hypogaeaL.)

Estimation of Genetic Parameters in Groundnut (Arachis hypogaea L.) for Yield and It’s Contributing Characters under Inorganic Fertilizer Managements

“…On contrary days to maturity showed lower estimates of coefficient of variation. The lower estimates of variability for days to maturity were in agreement with the reports of Patil et al, (2014) and Shukla and Rai (2014), thereby indicating narrow genetic variability for these characters in the material studied.…”

“…Moderate estimates of GCV and PCV were observed for days to 50 % flowering and shelling percentage. Moderate estimates of GCV and PCV recorded for days to 50 % flowering and shelling percentage were in accordance with the results of Patil et al, (2014) and Zaman et al, (2011) respectively. On contrary days to maturity showed lower estimates of coefficient of variation.…”

Genotype × Environment Interaction for Pod Yield in Groundnut

“…However, the magnitude of mean squares for environment (linear) was higher compared to genotypes × environments (linear) which indicated that, linear response of environment account for the major part of total variation for all the characters studied and which may be responsible for high adaptation. Similar results were also reported by Habib et al, (1986), Chuni Lal et al, (2006, Thaware (2009), Pradhan et al, (2010 and Patil et al, (2014). The mean squares due to pooled deviation (Non-liner) were significant for dry pod yield (kg/net plot) and kernel yield (kg/ net plot) ( Table 1).…”

“…Similar results of significant environment + (genotype × environment interactions) for various traits was reported by Joshi et al, (2003) and Patil et al, (2014). The mean squares due to G×E interactions were partitioned into linear and non-linear components.…”

“…The significant mean squares due to genotpes × environment (G×E) interactions were observed for all the characters except SMK (%) and Oil content (%) (Table 1) indicating the influence of environment on the genotypes evaluated. The significant genotype × environment (G×E) interactions for various traits were also reported by Hariprasana et al, (2008), Pradhan et al, (2010) and Patil et al, (2014).…”
