Abstract

The paper describes success story of Clonal Technology Research and Development Programme for genetic improvement of planting stock of Eucalypts through vegetative propagation and cloning techniques being implemented since 1989. Comparative data in respect of adaptability and growth rates has been presented and discussed. Details of most promising clones called 'Bhadrachalam' clones of Eucalypts selected for large scale commercial multiplication, with their origin and performance in various trials have been given. Progress of Eucalypt plantations, major constraints and factors contributing to success have been described. Development and deployment of genetically improved, high yielding, fast growing and disease resistant 'Bhadrachalam' clones of Eucalyptus on commercial scale for the first time in India, by a private sector company, ITC Bhadrachalam Paperboards Limited, have been highlighted.

Abstract

Forestry should be treated as a complementary rather than a competing land use, vis a-vis agriculture. National forests are under intense biotic pressure with low growing stock and poor productivity. Even after taking all possible measures for restoring the growing stock and improving land productivity of forests from the current level of 32 million m³/yr, it Will not be possible to meet the growing national needs for timber and wood projected at 418 million m³/yr by 2010 AD. Well-planned investment in technology based plantations, with genetically superior planting stock on vacant government lands, reclaimable wastlands, rail road and canal strips, combined with massive thrust in agroforestry plantations, should be a national priority. Improved package of practices, scientific management of plantations with accountability for results, technical extension services, long-term finance and marketing support for agroforestry plantations, will play a vital role in bridging the gap between demand and availability of wood. Such plantations will also generate ample employment opportunities for the rural poor and contribute immensely to the greening of the country, amelioration of the environment, maintenance of the ecological balance and life-support systems. Succesful implementataion of the reafforestation and agroforestry programmes will help sustain improvement of agricultural productivity and production through soil and water conservation and release large quantities of cow-dung for use as farmyard manure to restore soil fertility.

Abstract

Half-sib seedlings belonging to eight Santalum album trees located at different places were quantitatively measured for nursery characters to assess variability and superiority in seedling. Results revealed inter-tree variability was significant. It has also been assessed that the seedlings belonging to the tree numbers KL₃ K₃₃, K₂₆, and AP₄, are superior in performances and KL₃ be the best. The analysis of correlation coefficients among different characters indicate that the collar diameter is significantly negatively correlated with the shoot length. Shoot length and ischolar_main lengths are significantly and positively correlated.
