 ABSTRACT

Fourteen genotypes of groundnut were obtained from International Crop Research Institute for the Semi Arid Tropics (ICRISAT), Patancheru, Hyderabad, Andhra Pradesh, India were evaluated during Kharif season of 2013 for quantitative parameters. The crop was grown at the field experimental centre, Department of Genetics and Plant Breeding, Sam Higginbottom Institute of Agriculture Technology and Sciences, (Formerly Allahabad Agricultural Institute) Deemed-to-be-University, Allahabad, Uttar Pradesh. The present experiment was carried out in Randomized Block Design with three replications for variability, heritability and genetic advance. Observations were recorded on twelve quantitative characters. Analysis of variance revealed the presence of significant amount of variabilitymong the groundnut genotypes. Maximum genotypic coefficient of variation and phenotypic coefficient of variation was recorded for kernel yield (18.45q/ha.). All the characters showed maximum heritability was recorded for plant height (31.97 cm) and high genetic advance as percentage of mean was recorded for field emergence (235.5%). These characters may serve as an effective selection parameter during breeding programme for crop improvement in future.

Keywords Genetic variability, Genotypes, Groundnut, Quantitative parameters, RBD.
