IAPAR

IAPAR — the Instituto Agronômico do Paraná — was the public agricultural research institute of the Brazilian state of Paraná, headquartered in Londrina. It bred plants for farmers in one state, and the coffee half of that work is why it appears in an international variety catalogue: IAPAR 59, Brazil’s Sarchimor selection, carries its name.¹

It no longer exists as a standalone body. Paraná folded it together with the state’s farm-extension service, EMATER, into a single organisation now trading as the Instituto de Desenvolvimento Rural do Paraná – IAPAR-EMATER (IDR-Paraná), still run out of Londrina with an administrative office in Curitiba.² The old name survives on the seed.

To verify

Do not confuse IAPAR with IAC. They are two different state institutes in two different Brazilian states, and the abbreviations look alike. IAC is the Instituto Agronômico de Campinas, in São Paulo, founded 1887, which bred Mundo Novo and Catuaí. IAPAR is Paraná’s, founded roughly 85 years later. Trade sources sometimes blur them; the wiki keeps them separate deliberately.

What it is, plainly

A state government’s own farm science department. It did not sell coffee, own a brand or enter an auction. It ran experimental farms and laboratories, worked out which plants and which planting methods suited Paraná’s particular soil and cold, and handed the results to growers — the same job ICAFE does in Costa Rica, IHCAFE in Honduras and Cenicafé in Colombia, except that coffee was only one crop on IAPAR’s list.

Coffee is still visible in the successor institute’s day-to-day work: its site advertises frost alerts for coffee growers, a coffee extension programme, and the state’s own Concurso Café Qualidade Paraná — a Paraná coffee quality contest.²

To verify

The founding date, and the scale of the institute, rest on sources that could not be read from here. The research behind this note cites the Consórcio Pesquisa Café institutional page for a creation date of 29 June 1972, and for infrastructure of 19 experimental farms, 25 laboratories and 23 agrometeorological stations plus data from 37 more state weather stations. That server refused the connection when fetched.³ A SciELO paper on plant breeding at IAPAR returned HTTP 403.⁴ The 1972 year itself is independently corroborated by arithmetic on an Embrapa headline — “Iapar comemora 42 anos na vanguarda da pesquisa,” dated 1 July 2014, which puts the anniversary in mid-1972 — but Embrapa withholds the article body under Brazilian electoral-period publishing rules, so only the headline and dateline were readable.⁵ Treat 1972 as sound and the exact day and the facility counts as unconfirmed.

What it bred for coffee

IAPAR’s coffee output is a numbered series rather than a set of romantic names. Revista Cultivar, reporting on the state’s coffee programme, lists the institute’s cultivars in circulation as IPR 98, IPR 99, IPR 100, IPR 103, IPR 107 and IAPAR 59, selected for disease resistance and drought tolerance.⁶

Cultivar	What it is	Status on this wiki
IAPAR 59	Timor Hybrid 832/2 × Villa Sarchi — Brazil’s Sarchimor, dwarf, rust-resistant, medium altitude	Full note; agronomy confirmed at World Coffee Research1
IPR Alvorada	IAPAR 59 × Mundo Novo IAC 376-4 — dwarf-medium, high yield, good cup, only slight rust resistance	Full note; abstract confirmed at source, registration details unverified7
IPR 98 / 99 / 100 / 103 / 107	The rest of the IPR series, bred for resistance and drought	Named only in trade reporting6

The pattern is the giveaway. Every one of these was bred against a problem — Coffee leaf rust, drought, nematodes — rather than for a flavour. That is what a state institute serving commercial growers is for, and it is why the international catalogue rates IAPAR 59’s cup quality “Low” while rating its rust resistance and yield perfectly respectable.¹

To verify

A retailer’s account of IAPAR 59’s parentage contradicts the catalogue this wiki already relies on. A UK specialty retailer describes IAPAR 59 as a Mundo Novo × Caturra cross developed in the 1970s, and says the “59” is the number of the plot where the plant was first grown.⁸ World Coffee Research’s record — fetch-confirmed on the IAPAR 59 note — gives the parents as Timor Hybrid 832/2 × Villa Sarchi, which is a different lineage entirely and the only one consistent with the variety’s rust resistance.¹ Use the catalogue. The plot-number story for the “59” is charming and unsourced; no IAPAR or IDR document confirming it was located.

The state it was built for

Paraná is the cold edge of Brazilian coffee — the southernmost of the country’s coffee states and the one that freezes. That single fact shaped the institute’s coffee agenda.

The research report behind this note credits IAPAR with adapting “adensado” planting — high-density planting, meaning many more, smaller trees per hectare instead of fewer large ones — to Paraná’s climate and to the economics of small farms, and with helping rebuild the state’s coffee sector after the catastrophic 1975 frost.³ That source was unreachable, so it is reported here as claim rather than fact. What is readable independently is that high-density planting is described as “one of the pillars for the sustainability of coffee growing on small and medium-sized properties” in Paraná, and that the institute has run a frost alert service for growers since 1995.⁶

The scale of what was left to rebuild is worth stating. By 2016, Paraná’s coffee crop was around 47,300 hectares producing roughly 1.116 million 60-kg bags, at about 23.6 bags per hectare.⁶ Set that against Brazil as a whole, where Paraná ranks last among the six main coffee states, and the institute’s real subject comes into focus: not how to grow the most coffee, but how a marginal, frost-exposed, small-farm coffee region survives at all.

It has no competition record of its own

No cupping score, auction price, buyer or competition placement attaches to IAPAR. That is the correct answer for a breeding institute, not a gap: its output is seed, and the seed reaches the score sheet under a farmer’s name.

The one place its work brushes against the auction record is contested, and this wiki already flags it in detail.

To verify

The claim that an IAPAR variety won Cup of Excellence Brazil is single-sourced on the variety, not on the result. The result is confirmed at the Alliance for Coffee Excellence: Camocim Estate, producer Henrique Sloper, took first place at Cup of Excellence Brazil Naturals 2017 with 93.60 points, its top lot selling at US$90.20 a pound.⁹ What ACE’s results page does not state is the variety. The attribution of that lot to a “Catucaia-Açu Iapar 59” comes from one UK retailer’s blog post.⁸ See IAPAR 59 for the full treatment. Do not write “IAPAR’s variety won the Cup of Excellence” as established fact.

Where it went

The merger is the part with real consequences for anyone chasing a source. IAPAR’s technical sheets, cultivar records and publications now sit — where they survive at all — under IDR-Paraná, and this wiki has repeatedly failed to reach them: the IAPAR 59 note records the IDR-Paraná technical-sheet host timing out, and the institute’s own documents for the Sarchimor release remain unread here.¹⁰

To verify

The year and legal instrument of the merger are not confirmed. IDR-Paraná’s own site presents itself as “Instituto de Desenvolvimento Rural do Paraná – IAPAR-EMATER” with headquarters in Londrina and an administrative office in Curitiba — which confirms that IAPAR and the extension service EMATER were combined — but the page consulted gives no founding or merger date and no law number.² Brazilian state reorganisations of this kind are usually dated by statute; no such statute was located from here.

Why it matters

Two reasons, and neither is about flavour.

The first is that IAPAR is the counter-example to IAC. Both are Brazilian state institutes with long coffee programmes. IAC bred Catuaí and Mundo Novo and its material now underpins much of the country’s crop and a good deal of Central America’s. IAPAR bred a numbered series for one cold state, and its most famous variety is the one the international catalogue rates lowest in the cup. Same kind of institution, same country, opposite reputations — the difference is what each was asked to solve.

The second is the citation trail on this page, which repeats a pattern this wiki keeps hitting. A public institute with 50 years of coffee research has left, on the readable web, an official homepage under a new name, one 2016 trade article, and a headline with the body withheld. The reason we can say with confidence what IAPAR bred is that World Coffee Research, in another country, wrote it down and keeps the page up.¹ As on Instituto Agronômico and ISIC: institutional memory in coffee is thin, and it usually survives in somebody else’s catalogue.
