Estimates of genetic variability parameters for yield and yield attributes in groundnut (Arachis hypogaeaL.)

Estimation of genetic parameters for morpho-physiological responses in groundnut under rainfed condition

“…Moreover if the difference observed is wider between GCV and PCV the environmental influence on the expression of traits is greater and vice-versa. Similar results were reported by Prabhu et al (2015) [6] , John et al (2008) [7] , Tirkey et al (2018) [8] and Parameswarappa and Girish (2007) [9] . In this experiment, the characters which showed high heritability along with high genetic advance are kernel yield per plot, pod yield per plot, root weight, shoot weight, specific leaf area and proline content in the natural condition which concludes that these characters are governed by additive genes for which the selection will be effective for further crop improvement, also referred as fixable genetic variance.…”

Study of Genetic Variability and Character Association for Water Use Efficiency (WUE) and Yield Related Traits Advance Breeding Lines of Groundnut (Arachis hypogea L.)

“…Therefore, it was amply clear that these traits were less influenced by the environmental changes and hence improvement in these traits would be more effective through single selection owing to their additive gene effects and with simple phenotypic selection.

High heritability coupled with low genetic advance indicates the greater role of non-additive genetic variance like epistatic and dominant interaction factors controlling the inheritance of these traits.…”

Validation of SSR Markers for Foliar Disease Resistance in Groundnut (Arachis hypogaea L.)

“…These diseases also affect seed grade adversely and they markedly reduce haulm yield. Thus, breeding resistant cultivars is one of the best means of reducing crop yield losses from late leaf spot and also the best strategy to overcome additional cost of production (Prabhu et al, 2015). Selection of different genotypes under environmental stress conditions is one of the main tasks of plant breeders for exploiting genetic variations to improve disease tolerant cultivars (Clarke et al, 1984).…”
