Transgressive segregation for high shelling percentage in summer groundnut (Arachis hypogaea L.)

Abstract

The present investigation on transgressive segregation for high shelling percentage in summer groundnut (Arachis hypogaea L.) was undertaken to study eight characters. The crosses were evaluated during summer, 2017, in a randomized block design with three replications. Observations were recorded on number of mature pods/plant, dry pod yield/plant (g), dry haulm yield/plant (g), 100- kernel weight (g), shelling outturn (%), oil (%) and protein (%) contents, sound mature kernel (%). On the basis of performance of transgressive segregants, it was concluded that, transgressive breeding can be successfully used to extend the limit of expression of traits. This could be possible by accumulation of favourable genes in hybrid derivatives from both parents involved in hybridization. The superior segregants may be identified as improved varieties after adequate evaluation or used in future breeding programme for amalgamation of desired genetic constellations.
