Rasi 659 cotton hybrid

RCH-659 BG-II is a Bollgard-II Bt cotton hybrid from Rasi Seeds Pvt. Ltd., positioned as an early-to-medium duration hybrid for both rainfed and irrigated cultivation across central and southern Indian cotton tracts.

Key characteristics

  • Manufacturer: Rasi Seeds Pvt. Ltd.
  • Trait: Bollgard-II (Bt Cotton Bg Ii).
  • Duration: 145-160 days (early to medium).
  • Plant type: semi-erect, sturdy, with high boll retention and big bolls.
  • Recommended states: Karnataka, Andhra Pradesh, Telangana, Maharashtra, Madhya Pradesh and Gujarat.
  • Adaptation: rainfed and irrigated.

Cultivation

The 145-160-day duration makes RCH-659 a fit for double-cropping systems (Cotton Double Cropping Systems) in which a rabi maize, jowar, wheat or chickpea crop follows cotton on the same field. Standard package-of-practice fertilisation and weed management apply (Cotton First Dose Fertilizer, Cotton Weed Management). The sturdy semi-erect canopy suits both conventional and intermediate row spacing.

Pest profile

The Bollgard-II stack controls the lepidopteran bollworm complex but not the sucking-pest complex (Sucking Pest Complex Cotton) or non-lepidopteran pests. Pink Bollworm populations resistant to Cry1Ac and Cry2Ab require integrated management including timely sowing (Cotton Delayed Sowing Ipm) and refuge (Refuge In Bag Cotton).

Adoption and use

RCH-659 is one of the widely planted Bt cotton hybrids in the southern peninsular states. Field reports highlight clean bursting that simplifies hand-picking and resilience after moisture and pest stress.
