ABSTRACT
Thirty drought tolerant groundnut genotypes were evaluated for their variability with regards to yield, physiological and quality. Estimates of heritability, genetic advance and genetic advance as per cent mean were also obtained for the above traits. The results revealed high to moderate GCV and PCV in addition to high heritability and high genetic advance as per cent mean for haulm yield per plant and free proline content. Further, pods per plant, pod yield per plant, and 100 kernel weight had recorded high positive direct effects and strong positive associations with kernel yield per plant and are identified as effective selection criteria for kernel yield improvement in groundnut.
Key words :
Correlation, ECV, GCV, Heritability, Path analysis, PCV, Physiological, Variability, Yield & Quality traits.
