Abstract
Neolamarckia cadamba (Kadam) genetic resources were characterised Distinctness, Uniformity and Stability (DUS) traits based on International Union for the Protection of New Varieties of Plants12 guidelines. Twenty-five clones of kadam were characterised based on the morphological characters of leaf and bark with 12 descriptors. Among these 12 descriptors, 9 were qualitative traits viz., leaf shape, Leaf base shape, apex shape, leaf margin, leaf venation, base symmetry, Waxiness in upper side of leaf, bark colour and bark texture and 3 were quantitative characters viz., leaf length, leaf breath, leaf petiole length. The study exhibited significant variations among the genetic resources investigated for various DUS traits, which could act as reference traits for developing variety to protect the genetic resources through Intellectual Property Rights.
Highlights
Neolamarckia cadamba Miq., (Family-Rubiaceae) commonly called as Kadam is one of the best sources of raw material for plywood industry, besides pulp and paper production
The clonal evaluation trial comprises twenty-five clones and these clones were subjected to DUS characterization for the characters viz., leaf shape, base shape, apex shape, leaf margin, leaf venation, base symmetry, leaf length in cm, leaf breath in cm, leaf petiole length in cm, Waxiness in upper side of Leaf, bark colour and bark texture and observations were recorded as per UPOV.[12]
Twenty-five Neolamarckia cadamba clones characterized for DUS traits in order to protect the genetic resources through possible IPR mechanism
Summary
Neolamarckia cadamba Miq., (Family-Rubiaceae) commonly called as Kadam is one of the best sources of raw material for plywood industry, besides pulp and paper production. Its leaves have used as fodder to cattle.[1] The leaf area, pruning frequency, moisture content and nutritional characters of this species outreached it as an excellent fodder tree, which used to meet the green, dry and concentrate feed utility. Such a multiple utility tree reached only little research attention. Forest College and Research Institute, Mettupalayam has undertaken the improvement program through progeny and clonal tests
