Genetic variability and correlation study for growth characters among clones of Eucalyptus

Abstract

The present investigation was carried out in College of Forestry, Navsari Agricultural University, Navsari, Gujarat to study the genetic variability, heritability, genetic gain, genetic advance and correction for growth traits among 20 clones of Eucalyptus. Low to medium values for PCV, GCV, ECV, heritability, genetic advance and genetic gain were recorded among different growth parameters. Among different genetic variability volume was found maximum in GCV with 22.67 per cent, heritability with 0.52 and genetic gain with 33.78 per cent. Similarly significant and positive correlation of volume with DBH, mid-diameter, tree height and form quotient was observed. From the study, it is evident that volume was with maximum genetic variability and showed positive correlate with all the remaining growth characters. Hence, clone(s) with maximum volume could be used for clonal improvement programme in South Gujarat condition.
