Assessment of genetic variability for yield and component traits in groundnut (Arachis hypogaea L.) germplasms in sodic and normal soil condition
Abstract
Groundnut is a predominant oilseed crop in India and ranks first among the edible oilseed groups, which produces high nutritive value kernels. A field experiment was conducted involving 55 groundnut accessions to evaluate their performance under sodicity by relative comparison with normal sandy soil during Kharif, 2019. The genotypes VG 18096, VG 15008, TMV 13 and VG 18100 recorded high per se performance for pod yield and kernel yield per plant under sodic soil condition. Higher estimates of phenotypic and genotypic coefficient of variation was recorded for the number of matured pods per plant (32.37 and 27.22), pod yield per plant (29.53 and 23.80) and kernel yield per plant (29.45 and 21.44). Heritability and genetic advance as per cent of the mean was found to be high for the number of matured pods per plant, hundred kernel weight and pod yield per plant, which indicated that these traits were governed by additive gene action and were less influenced by the environment. These traits could be improved through simple phenotypic selection.
