Genetic analysis of fruit and seed parameters in teak (Tectona grandis L. F.): Implications in seed production programme

Genetic analysis of fruit and seed parameters in teak (Tectona grandis L. F.) was carried out using open pollinated fruits from 40 plus trees of Madhya Pradesh, Central India. The results indicated highly significant variation for all the characters studied. Fruit size, fruit weight and seed weight exhibited moderately high to very high heritabilities coupled with relatively high genetic gain for fruit and seed weight. Fruit size showed significant phenotypic and high genotypic correlations with fruit weight filled and unfilled locule. Implications of the present findings in seed production programme of teak have been discussed.
