ABSTRACT

Twenty Spanish bunch groundnut genotypes were evaluated for genetic parameters of 19 characters of morphological, physiological, yield and yield attributes over three seasons viz., Late Kharif (2012), Rabi (2012-13) and Summer (2013). The pooled data over three environments revealed that the genotype JL 24 showed lowest mean value for days to maturity, highest mean value for SCMR at 40 DAS and SCMR at 50 DAS. The genotype Abhaya showed highest mean value for pod yield per hectare and oil yield per hectare. Results indicated that PCV estimates were higher than those of GCV for all the characters studied indicating the influence of environment in varying degrees on all the characters. The results revealed that highest GCV was observed for pod yield per plant. Moderate heritability accompanied with high genetic advance as per cent of mean was recorded for pod yield per plant, pod yield per hectare (q), kernel yield per plant (g), kernel yield per hectare (q) and oil yield per hectare (q) indicating the preponderance of additive gene action which may be exploited through simple selection procedures.
