An Italian farmer has made a significant agricultural discovery after planting seeds found in his family’s attic. Claudio Grossi, who farms near Parma in northern Italy, uncovered a rare heritage wheat variety that could provide valuable insights for agriculture in the face of climate change. The seeds, which Grossi believed belonged to his late great-grandfather, germinated into a remarkable plant that produced seven ears of grain on a single stalk, a phenomenon that is uncommon in modern wheat varieties.

The seeds were discovered in the early 1990s while Grossi was cleaning his attic. Despite their dry and cracked appearance, he scattered them over manure and was surprised when they sprouted. Among the various plants that emerged, one stood out due to its impressive height of approximately six feet and its distinctive formation of seven ears, which included a long central ear surrounded by six shorter ones.

This unusual growth pattern led Grossi to reflect on a biblical passage from the Book of Genesis, where Joseph interprets a dream involving seven full ears of grain. Although Grossi found a connection to the biblical narrative, it served as inspiration for his further investigation rather than as scientific validation of the plant’s origins.

Identification and Characteristics of the Wheat

The identification of the wheat was achieved through research conducted by Beniamino Perobelli, a student at the University of Parma. His undergraduate thesis focused on the nutritional properties of the grain, which was eventually classified as Triticum turgidum, commonly known as poulard wheat. This species has historical roots in areas such as modern-day Turkey and Egypt, and it was previously cultivated in Italy before the shift to higher-yielding commercial varieties.

Grossi named the wheat grano del miracolo, or “miracle grain,” after observing its resilience during drought conditions. He noted that it outperformed commercial wheat varieties, growing tall enough to overshadow competing weeds and requiring less dependence on fertilisers and herbicides. Additionally, preliminary research indicated that this heritage wheat contained higher levels of phosphorus and iron compared to modern wheat, along with lower gluten levels and beneficial amino acids.

However, Grossi faced challenges in baking with the flour produced from this wheat. The dough did not rise as effectively as that made from conventional wheat, leading him to collaborate with a local baker. Through experimentation with different techniques, they eventually produced a bread with a rich, nutty flavour that was distinct from typical commercial bread.

Potential Implications for Modern Agriculture

This discovery highlights the importance of genetic diversity in agriculture, particularly as modern farming often relies on a limited range of crop varieties. While these varieties have contributed to increased food production, they can also make agricultural systems susceptible to challenges such as drought and pests. Francesco Sottile, an expert in agrosystem biodiversity, emphasised the value of crop diversity, noting that heritage grains could provide alternatives in adverse conditions.

For instance, during a severe drought in Sicily in 2024, many conventional wheat growers abandoned their fields, whereas smaller farmers cultivating heritage grains managed to harvest their crops. This situation underscores the potential benefits of investigating traditional varieties, although it does not guarantee that all ancient grains will outperform modern counterparts under every circumstance.

Despite its advantages, the miracle wheat has limitations, such as vulnerability to extreme weather conditions. Grossi has addressed this by planting it alongside shorter wheat varieties that offer structural support. Ultimately, the significance of this discovery lies in its ability to reintroduce genetic diversity and traditional farming knowledge into contemporary agricultural discussions, which may be crucial as climate pressures continue to escalate.
