About this variety
DCH-32 (also marketed as Jayalaxmi) is an interspecific cotton hybrid bred by Dr. B.H. Katarki at the University of Agricultural Sciences (UAS), Dharwad, Karnataka, released in 1981 for commercial production in India's southern and central cotton belts, per corroborated secondary sources. It is a cross of DS 58 (Gossypium hirsutum, the seed/female parent) and SB 425 YF (Gossypium barbadense, the pollen/male parent), combining hirsutum vigour with barbadense's extra-long, fine fibre. Though released specifically for Karnataka, its wide adaptability saw it spread to Tamil Nadu, Andhra Pradesh and western Maharashtra — a broader footprint than this record's own three-state field captures.
Key characteristics
Yield & maturity
Maturity period
170–180 days
Expected yield
10–15 q/ha seed cotton
Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.
Pest & disease considerations
Major diseases
- Moderate; bred mainly for fibre quality, not pest or disease resistance
Advantages & considerations
Why farmers may choose it
- Combines G. hirsutum vigour with G. barbadense's extra-long, fine fibre quality — the specific reason it was bred as an interspecific cross rather than a within-species selection
- Wide adaptability beyond its original Karnataka release zone, into Tamil Nadu, Andhra Pradesh and western Maharashtra
Things to consider
- Corrected 2026-08-15: added Maharashtra to states — a directly-fetched source (Dr. B.H. Katarki / UAS Dharwad release material) describes DCH-32's spread into western Maharashtra beyond its original Karnataka/Tamil Nadu/Andhra Pradesh footprint

Frequently asked questions
What is the parentage of DCH-32 cotton?
An interspecific cross of DS 58 (Gossypium hirsutum) and SB(YF) 425 (Gossypium barbadense), bred by Dr. B.H. Katarki at UAS Dharwad.
When was DCH-32 released?
1981, by the University of Agricultural Sciences, Dharwad, for Karnataka, though it later spread more widely.
Why is DCH-32 an interspecific hybrid?
It crosses G. hirsutum (vigour, adaptability) with G. barbadense (extra-long, fine fibre) to combine both species' strengths in one hybrid.
Which states actually grow DCH-32?
Beyond its original Karnataka release, it spread into Tamil Nadu, Andhra Pradesh and western Maharashtra.
Is DCH-32 bred for pest or disease resistance?
No — per this record's own field, it was bred mainly for fibre quality, not pest or disease resistance, consistent with its interspecific-cross breeding purpose.
