Grand Naine (G9)
Planted as tissue-culture plantlets, not true seed. The Cavendish clone behind most of India’s commercial banana — uniform bunches that the export and modern-retail trade both grade well.

About this variety
Grand Naine — often written 'Grand Nain', French for 'large dwarf' — is a Cavendish-subgroup cultivar of Musa acuminata (AAA genome) that sits at an intermediate height between the shorter Dwarf Cavendish and taller Giant Cavendish clones, per a directly-fetched Wikipedia article. It is the most widely traded Cavendish banana in the world and the main cultivar behind Chiquita Brands' fruit; commercial planting material was brought into India from Israel in 1995, and tissue-culture G9 plantlets — the same 'not true seed' propagation this record's own note describes — now account for roughly 17% of all banana-planted area nationally. Like every Cavendish clone, Grand Naine is essentially a single genotype propagated by cloning, which the Wikipedia article notes leaves it with very little internal genetic diversity to draw on against a new pathogen. That vulnerability is no longer theoretical in India: a directly-fetched Down To Earth report describes Fusarium wilt tropical race 4 (Foc TR4) first being confirmed on Cavendish bananas — specifically Robusta and Grand Naine — in Bihar's Barari village in 2015, with disease incidence of 2–26.6% in that first outbreak, and it has since spread to more than 8,474 hectares in Uttar Pradesh and over 3,000 hectares in Bihar, with Siddharthnagar district in UP identified as a hotspot. Because Cavendish varieties (Grand Naine plus Robusta) together cover about 52% of India's banana-growing area and 64% of national production, this spread is a systemic risk rather than a localised one — the same report distinguishes infected G9 plants, which reportedly 'break off and give a bad smell', from some traditional varieties that show milder symptoms.

Pest & disease considerations
Advantages & considerations
Why farmers may choose it
- Uniform, high-volume bunches and fruit sizing that export and modern-retail buyers grade well, the reason it has become India's dominant commercial Cavendish clone
- Confirmed field resistance to the older Fusarium wilt race 1 that wiped out the earlier Gros Michel-type Cavendish predecessors worldwide decades ago
- Widely available as certified tissue-culture plantlets, giving more uniform, disease-screened starting material than sucker propagation
Things to consider
- This record's own diseaseResistance field already states Grand Naine is 'not resistant to the newer Foc TR4 strain' — sourced reporting fully bears this out: TR4 was first confirmed on Grand Naine in India in a 2015 Bihar outbreak and has since spread across thousands of hectares in UP and Bihar, with Grand Naine explicitly named among the highly susceptible commercial varieties
- Because Grand Naine is a clonal monoculture like all Cavendish types, there is no internal genetic variation to select resistant plants from within the variety itself — growers in TR4-affected tracts are generally advised toward strict clean-planting-material and quarantine protocols, or alternative varieties, rather than simply replanting G9
- Nothing sourced here contradicts this record's fields; the detail mainly adds the scale and history behind the caution the record already carries

Frequently asked questions
Where did Grand Naine (G9) originally come from?
It is a Cavendish-subgroup clone (AAA genome) brought to India from Israel in 1995 for commercial cultivation — not an Indian-bred variety — and tissue-culture G9 plantlets now cover roughly 17% of India's total banana area.
Is the TR4 threat to Grand Naine real in India today, or just a risk elsewhere?
It is already established here — TR4 was first confirmed on Grand Naine and Robusta in Bihar in 2015 and has since spread to over 8,474 hectares in Uttar Pradesh and 3,000+ hectares in Bihar, with Siddharthnagar district in UP flagged as a hotspot.
