About this variety

The IFGTB EC-series clones (EC-1 through EC-4) were released by the Institute of Forest Genetics and Tree Breeding (IFGTB), an ICFRE institute based in Coimbatore, from its eucalyptus tree-improvement programme. These clones are broadly cultivated across Andhra Pradesh and Tamil Nadu for industrial pulpwood plantations, propagated through tissue culture and mini-cutting protocols developed specifically to multiply superior, high-productivity genotypes at scale for the region's pulp and paper industry.

Sowing & cultivation

  • Spacing3 x 2 m or 2 x 2 m for a dense pulpwood block; 4 x 4 m for pole/agroforestry planting

Yield & maturity

Maturity period

5-6 year rotation to clear-felling

Expected yield

High; developed specifically for pulpwood productivity

Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.

Pest & disease considerations

Major diseases

  • Moderate; screen for gall-wasp tolerance locally

Advantages & considerations

Why farmers may choose it

  • Bred specifically for pulpwood productivity by a dedicated ICFRE tree-genetics institute
  • Well established in Andhra Pradesh and Tamil Nadu's industrial pulpwood belt, with local agronomic experience readily available
  • Multiplied through modern tissue-culture and mini-cutting protocols for consistent, uniform planting stock

Things to consider

  • Gall-wasp (Leptocybe invasa) tolerance varies by specific clone and site — screen locally with your IFGTB or state forest department contact before large-scale planting
  • Best suited to the peninsular pulpwood belt it was developed for; not specifically evaluated for Punjab's saline/waterlogged conditions the way PE-11 is

Suitable regions

States this variety is recommended for — check locally, since a state can have more than one recommended zone.

  • Andhra Pradesh
  • Tamil Nadu
