Extra long staple (ELS) cotton in India: Suvin, DCH-32, MCU-5

Extra long staple (ELS) cotton — staple length 32 mm and above — is the premium segment of Indian cotton, used to spin fine count yarns (80s and above) for high-value fabrics, denim premium and export. India produces a small share of its total cotton — roughly 2-4 lakh bales out of 35 million annually — as true ELS, leaving the country a net importer of ELS from Egypt and the United States despite being the world's largest overall cotton producer.

Key ELS cultivars

  • Suvin: a G. barbadense × G. hirsutum derivative released from the Central Institute for Cotton Research-Coimbatore station in 1974, considered India's flagship ELS. Staple length 38-40 mm, micronaire 3.0-3.4, ginning out-turn ~ 33%. Grown almost entirely in Tamil Nadu under irrigation. Acreage has collapsed from a peak in the 1980s to a few hundred hectares today.
  • DCH-32: an intra-hirsutum × barbadense hybrid released from the Agricultural Research Station, Dharwad in 1983. Staple length 33-36 mm, micronaire 3.5-3.8, ginning out-turn ~ 34%. The dominant commercial ELS hybrid, grown across Karnataka (Dharwad, Haveri, Belgaum), parts of Tamil Nadu and Maharashtra.
  • MCU-5: a G. hirsutum variety released from Madurai-Coimbatore Unit-5, staple length 30-32 mm, on the lower boundary of the ELS range. Suited to Tamil Nadu rainfed and partially irrigated tracts.
  • CICR varieties: CCH-5363, Surabhi and SVPR-2 are additional ELS-range options under AICRP.

Why ELS production has shrunk

ELS varieties have not been backcrossed to incorporate the Bollgard-II Bt trait — a regulatory and commercial gap. Without Bt protection, ELS hybrids suffer heavy bollworm losses (see Cotton American Vs Desi Vs Egyptian for the broader Bt context). DCH-32 and Suvin require labour-intensive picking with multiple selective rounds to preserve fibre quality. Yield per hectare is roughly 40-60% lower than medium-staple Bt hybrids, and the additional ELS-MSP premium (Cotton Cci Msp Procurement National) is insufficient to offset the gap. Picking-labour scarcity has further squeezed economics.

Demand side

Premium Indian textile mills (Coats, Vardhman, Trident, Loyal Textile, Arvind) require ELS for export-grade product. They source approximately 70-80% of their ELS through imports from Pima (United States) and Giza (Egypt) cottons. CITI and Texprocil have repeatedly petitioned for a focused ELS revival programme.

Revival efforts

ICAR-CICR launched a National ELS Cotton Mission proposal in 2019 and the Ministry of Textiles announced a Cotton Sector Development Scheme. Targeted research includes (a) introgressing Bt traits into ELS background — pre-commercial trials; (b) compact ELS genotypes for HDPS; (c) mechanical picking compatible varieties to reduce labour cost.
