Abstract

Experiments were carried out with a view to assess the variability in 23 one-parent families of Mahua [Madhuca latifolia (Roxb) Macbrid], representing different agroclimatic zones of Tamil Nadu. Results indicated distinct variation among the 23 one-parent families in respect of seed characters like seed length, seed breadth, seed length : seed breadth ratio, hundred seed weight and oil content and seedling traits like shoot length, basal diameter, ischolar_main length, number of leaves and total dry weight. Out of the 23 one-parent families studied, TNAU and Paiyur-I were found to be suitable for short rotation forestry practices.

Abstract

To improve the growth and yield of Acacia nilotica Linn. (Babul) a study was conducted using genetically superior elite trees. The study revealed that the selected traits viz. plant height, basal diameter, number of branches and volume were highly significant which indicate higher variability among half-sibs. Further, regression analysis revealed that the half-sibs of TNPKM1 and KRKL2 are best and may be utilized for future breeding programmes. Overall study implies that the traits like plant height, basal diameter and number of branches have maximum influence on volume, hence the traits will be useful in selecting Acacia nilotica trees for agroforestry development programmes.
