Sinar Mas Pulp and Paper, based in Pune district has also turned out to be a relatively cleaner mill.
Yet rubber improvement projects in India have focused mainly on increasing latex production. Currently, rubber growers are facing difficult times with decline in rubber prices, reduced returns and high labour costs.
New developments in rubber science can help farmers overcome these problems to a certain extent. Rubber tree — Hevea brasilensis — is a major plantation crop in Kerala and North-Eastern states.
Latex obtained from tapping this tree is used as raw material for tyre production and other products like condoms and surgical gloves. The productivity of even superior yielding clones declines after 25 years. So mature trees have to be felled eventually and replanted. Conventionally, felled rubber wood is used for making packaging cases as it is of poor quality and deteriorates with fungal decay.
Hence, it is not generally useful for other purposes like making furniture. New developments in wood science and technology like finger jointing technique, preservative applications have opened new avenues of utilization. There is a good response for rubber wood furniture in the market because of its good aesthetic look and low cost.
Some rubber growing countries like Malaysia have attempted to develop rubber tree that can be used for latex production initially. After its latex yield declines, the tree can be felled and rubberwood used for other applications. Such dual-purpose rubber clone or progeny can provide double income to growers.
Yet rubber improvement projects in India have focused mainly on increasing latex production and neglected improving wood quality traits. Now this can change.
Earlier studies have proved that selective breeding and hybridization programmes can improve the wood quality characters in tropical trees.
Recently, scientists from the Rubber Research Institute of India, Kottayam have taken initial steps towards breeding dual purpose rubber clones.
They have studied wood properties variation and heritability of 11 progenies obtained from crossing superior latex yielding rubber clones which are cultivated on large scale.
Wood samples were collected from these progenies as well as their individual parental clones for estimating wood specific gravity and fibre traits. Primarily, wood specific gravity is a highly heritable character in trees and it decides the timber utility.
Researchers interpreted the growth traits of the trees with wood properties and found that wood specific gravity did not show any significant correlation with growth traits.
Hence, they are hopeful that they can improve wood specific gravity independently in rubber tree without compromising growth and latex yield. The wood characteristics like fibre length, fibre diameter, lumen diameter and thickness of fibre wall determine structural, physical and chemical properties of wood.
So information on their genetic control and heritability becomes vital in planning tree improvement programmes. Based on the results of this study, scientists have concluded that there is a positive genetic relationship between rubber tree growth traits and fibre diameter as well as fibre wall thickness.

However, they also state that fibre length was negatively correlated to tree growth. Fibre length, however, is an important criterion for pulp and paper production. This necessitates different breeding approach if the objective is pulp and paper production from the rubber tree.
In order to use rubber wood for paper and pulp, there is a need to sort out latex depositing issue on the pulp. This might need an interdisciplinary research. Based on this study and other existing information, scientists are confident they can manipulate wood traits suited to for pulp and paper production.
In addition, the conventional method of developing clones through hybridization and selection in rubber trees is a long-term programme.
This research highlights the significance of tree breeding programmes for improving productivity and it also necessitates the need for understanding the basics before initiating tree breeding projects aimed at increasing productivity.
