Pusa Nanha
From IARI — a dwarf, compact release bred for kitchen gardens and high-density planting, fruiting close to the ground where Pusa Delicious and CO 7 both grow much taller.

- Developed at the ICAR-IARI Regional Station, Pusa, Bihar.

About this variety
Pusa Nanha is an ultra-dwarf, dioecious papaya line developed at the ICAR-IARI Regional Station, Pusa, Bihar. Search results consistently describe it as a mutation-breeding product — seeds of an existing line, 'Pusa 1-15', irradiated with 15 Kr of gamma rays to fix a stable dwarf, uniform, high-yielding type — though no directly-fetched primary page stated this method explicitly, so it is reported here as WebSearch-corroborated across multiple independent hits rather than sourced to one fetched document. A directly-fetched National Horticulture Board (NHB) project report confirms a closer 1.2 × 1.2 m spacing is specifically recommended for cv. Pusa Nanha under high-density planting, and lists it (with Pusa Delicious) among varieties grown in Karnataka, Kerala, Jharkhand and Odisha, beyond this record's own Delhi/Uttar Pradesh states field. A directly-fetched Biotech Articles roundup adds that the plant can keep producing fruit for up to three years and confirms the IARI, New Delhi breeding attribution. A second trade source (AgriBot, directly fetched, lower-tier but consistent with the practical figures) puts the tree at 4–5 feet tall, bearing 500–700 g fruit with deep-orange, aromatic flesh from around 9–10 months after planting — close to, but a touch later than, this record's own 8–9-month first-harvest field; a directly-fetched Farm Extension Manager page independently confirms the IARI Regional Station, Pusa origin and the same kitchen-garden/pot/rooftop framing. Because of its dwarf stature it is specifically marketed for kitchen gardens, containers and rooftop cultivation, distinct from the taller, more spreading habit of standard varieties like Pusa Delicious and CO.7.

Advantages & considerations
Why farmers may choose it
- Ultra-dwarf habit (about 4–5 feet) suited to kitchen gardens, containers and rooftop cultivation — a genuinely different niche from taller, orchard-style varieties like Pusa Delicious and CO.7
- A directly-fetched National Horticulture Board project report specifically recommends a closer 1.2 × 1.2 m spacing for high-density planting of this variety
- Can keep bearing fruit for up to three years per a directly-fetched trade roundup, useful for a variety often grown in small home-garden plots rather than replanted annually
Things to consider
- Its mutation-breeding origin (gamma-irradiated Pusa 1-15) is repeated consistently across search results but could not be confirmed from a single directly-fetched primary page this pass — reported as WebSearch-corroborated rather than fully sourced
- Sourced first-fruiting timing (about 9–10 months, per a directly-fetched trade source) runs a touch later than this record's own 8–9-month first-harvest field — a minor gap, not a contradiction
- Also grown well beyond this record's own Delhi/Uttar Pradesh states field — a directly-fetched National Horticulture Board project report additionally lists Karnataka, Kerala, Jharkhand and Odisha

Frequently asked questions
Why is Pusa Nanha so much shorter than other papaya varieties?
It's widely reported to be a mutation-bred line — seeds of an earlier IARI line, Pusa 1-15, treated with gamma radiation to fix a stable dwarf, uniform type — rather than a cross-bred hybrid. That's why it stays around 4–5 feet tall, against the much taller habit of standard varieties.
What planting spacing suits Pusa Nanha's dwarf habit?
A directly-fetched National Horticulture Board project report recommends a closer 1.2 × 1.2 m spacing for high-density planting of this specific variety — tighter than the spacing typically used for taller papaya types.
