What Is Catimor Coffee? Key Traits and Yield Data

If you’ve ever wondered why some coffee farms in China consistently produce high yields without falling victim to leaf rust, the answer often lies in the variety planted. One name comes up repeatedly in agricultural reports: Catimor. But what makes this variety so widely adopted—and what should growers (or curious coffee pros) know about it?

Catimor is a high-yielding, compact coffee plant with strong resistance to coffee leaf rust. Its seeds remain highly viable for up to three months post-harvest, and field trials show it regularly outperforms traditional varieties like Typica and Bourbon. Read on for the detailed numbers behind its performance and key characteristics.

What Are the Key Characteristics of Catimor Coffee?

Catimor coffee seeds exhibit notable viability over time: at two months of sun-drying, there are approximately 3,846 seeds per kilogram, increasing to around 5,000 seeds after five months. Seed germination rates are above 95% within the first two months post-processing, drop to 85% after three months, weaken further after that, and most seeds lose viability entirely after six months. The plant itself features a compact growth habit, offers sub-immune or very high resistance to coffee leaf rust, and shows some natural suppression of longhorn beetles that typically target exposed tree trunks. These factors—along with stable, high annual yields and minimal alternate-bearing—have made Catimor a leading cultivated variety since its introduction.

How Has Catimor Performed in Yield Trials?

Field tests across different regions of China confirm Catimor’s reputation as a reliable high-output variety. Under proper cultivation techniques, it regularly achieves average yields above 150 kg per mu (approximately 0.067 hectares), with small plots reaching over 400 kg per mu. Specific trial results include:

• Lujang Farm (Baoshan, Yunnan): Planted in March 1991, this 12.6-mu irrigated plot (without shade) saw yields of 75 kg/mu in the 1993/94 season, rising to 350 kg/mu in 1994/95, then 225 kg/mu in 1995/96—averaging 217 kg/mu across three years. That’s 36% higher than Typica and Bourbon, which averaged 160 kg/mu.
• Dehong Tropical Agriculture Research Institute (Yunnan): With 30 mu planted in 1991 (no shade or irrigation, medium management), average yields hit 304.3 kg/mu in 1993/94, 294 kg/mu in 1994/95, and 222.5 kg/mu in 1995/96—3-year average 273.6 kg/mu, 82% higher than S288’s 150 kg/mu.
• Gaitian Coffee Base (Ning’er, Yunnan): 50 mu planted in July 1998 (low fertilizer, no shade but fertile soil), began fruiting in 2000. Averaged 285 kg/mu in 2001/02, 340 kg/mu in 2002/03, and 293 kg/mu in 2003/04—3-year average 306 kg/mu, 53% higher than PT and 91% higher than P4 (200 kg/mu and 160 kg/mu respectively).

Why Do Growers Continue to Plant Catimor?

Beyond raw yield numbers, growers favor Catimor for several practical reasons. Its compact plant form makes it easier to manage and harvest. The sub-immune or very high resistance to coffee leaf rust is invaluable in humid environments where the disease is prevalent. The three-month window of high seed germination offers flexibility in nursery operations. Additionally, its consistent output with minimal “off” years helps farmers maintain steady production and income. These combined traits explain why Catimor has remained a dominant variety in commercial coffee planting since its introduction.

Frequently Asked Questions

How many Catimor seeds are in a kilogram after drying?

After two months of sun-drying, there are approximately 3,846 Catimor seeds per kilogram. This increases to around 5,000 seeds after five months of drying.

How viable are Catimor coffee seeds over time?

Catimor seeds have a germination rate above 95% within the first two months after processing. This drops to 85% after three months, weakens further beyond that, and most seeds lose viability completely after six months.

Does Catimor resist coffee leaf rust?

Yes, Catimor shows either sub-immune or very high resistance to coffee leaf rust, a major advantage in regions where the disease is common.

How does Catimor perform compared to traditional varieties like Typica and Bourbon?

In multiple trial locations, Catimor consistently outyields Typica and Bourbon. For example, it produced 36% more coffee per mu than those varieties in one Yunnan test and significantly higher yields in others.

What kind of growing conditions does Catimor need to perform well?

While Catimor performs best with moderate management and some fertility, trials show it can thrive with low fertilizer, no shade, and minimal irrigation—as seen in several Yunnan test sites—still achieving high yields.

What is the average yield of Catimor per mu?

Under proper cultivation techniques, Catimor averages over 150 kg per mu, with small plots reaching over 400 kg per mu in optimal conditions.
