Genetic variability and correlation studies for morphological, yield and yield attributes in groundnut (Arachis hypogaeaL.)

Assessment of genetic variability for yield and component traits in groundnut (Arachis hypogaea L.) germplasms in sodic and normal soil condition

“…This suggested higher genetic quotient in the inheritance of the above traits and hence the selection could be done based on the above traits. Similar results were obtained for matured pods by Vasanthi et al (2015) and for kernel yield per plant by Chavadhari et al (2017) and seed yield by Singh et al (2008). Moderate GCV was obtained for hundred kernel weight (18.85) and plant height (14.1) while it was low for pod length (7.98), the number of branches per plant (6.59), shelling percentage (6.17) and days to 50% flowering (3.61).…”

Combining Ability Studies for Yield and Its Component Traits in Groundnut (Arachis hypogaea L.)

“…The results were in agreement with findings of Kavani et al, (2004), John et al, (2011) and Padmaja et al, (2015) for haulm yield per plant and Vasanthi et al, (2015) for pod yield per plant. For the traits plant height and chlorophyll content high × low gca combination of parents were more observed indicating the predominance of additive × non-additive type of gene action, which were in accordance of Mohan et al, (2012).…”

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

“…The traits viz., sound mature kernel percentage, harvest index, plant height and 100 kernel weight recorded moderate estimates of GCV and high PCV values. The results of Vasanthi et al, (2015) and Bhargavi et al, (2016) were similar to the present report of moderate GCV and high PCV estimates for 100 kernel weight and harvest index, respectively. Moderate estimates of GCV and PCV were observed for days to 50 % flowering and shelling percentage.…”

“…The estimates of phenotypic coefficient of variation were higher than genotypic coefficient of variation for all the 14 characters indicating the influence of environment in the expression of these traits. Similar kind of observations were also reported by Zaman et al, (2011), Satish (2014, Vasanthi et al, (2015), Jibrin et al, (2016) and Kamde et al, (2017).…”
