Abstract

ABSTRACT An experimental seedling seed orchard of shisham was planted in February, 1975 for production of genetically superior seed of shisham for planting. Each of 24 blocks in 1.3 acres plantations contains one plant from each of 40 open- pollinated families of selected trees of this species. Seedlings within families were selected for straightness of stem and height growth. Selection thinning in the experimental plantation will leave only the best individual trees to produce seed. Seedlings were assigned to blocks according to size ranking within the families, with a view to reduce the influence of nursery environment variation on the selection outcome.
