BIOINFOLET - A Quarterly Journal of Life Sciences

A field experiment was conducted with three F₂ populations of the crosses Chintamani 2 × ICGV 00350, TAG 24 × ICGV 86031 and TMV 2 × JL 42 to find out the extent of genetic variability, heritability and genetic advance for pod yield and its attributing characters in groundnut (Arachis hypogaea L.). The estimates of PCV and GCV were high for number of branches per plant, pod yield per plant, kernel yield per plant, and oil yield per plant in all the three crosses and matured pods per plant in the crosses TAG 24 × ICGV 86031 and TMV 2 × JL 42. High heritability estimates were observed for days to fifty per cent flowering, sound mature kernel per cent, shelling per cent, oil content, specific leaf area, kernel yield per plant and pod yield per plant in all the three crosses. The expected genetic gain, expressed as per cent of mean, was high for number of branches per plant, matured pod per plant, shelling per cent, kernel yield and pod yield per plant for all the three crosses. The remaining characters showed moderate to low genetic advance as per cent of mean values. High heritability coupled with high genetic advance was noticed for number of branches per plant, kernel yield per plant, oil yield per plant and pod yield per plant in all the three crosses.
