Israeli Innovation Aims to Transform Medical Cannabis Production with Hybrid Seed Technology

Producing medical cannabis with consistent quality and uniformity has long been one of the industry's greatest challenges. Israeli company RCK, based at Kibbutz Ruhama in the western Negev, believes it has found a solution. After years of research and development, and despite the severe disruptions caused by the October 7 Hamas attacks and the ensuing war, the company has unveiled a breakthrough technology that has increased seed production by 17.5 times—a development that could significantly reshape the global cannabis industry while contributing to the economic resilience of Israel’s southern region.
The innovation was presented at the “Sowing the Future” conference organized by Israel’s Ministry of Agriculture and Food Security. At the center of this achievement is Dr. Silit Lazare, RCK’s Chief Scientific Officer, whose work has helped position Israel at the forefront of agricultural biotechnology.
“Today, most cannabis cultivation relies on vegetative propagation,” Dr. Lazare told Itonnews. “These are essentially clones taken from a mother plant. Our technology is different because it uses true F1 hybrid seeds. We cross two carefully developed and stabilized parental lines, allowing us to produce highly uniform seed lots.”
According to Lazare, the advantages of hybrid seeds are considerable. For large-scale producers, seeds are easier to store, transport, and manage. They have a significantly longer shelf life, eliminate the need to maintain mother plant nurseries, and reduce some of the logistical and phytosanitary risks associated with vegetative propagation.
Dr. Lazare’s journey to this breakthrough reflects her diverse background.
Raised in an agricultural family, she studied agronomy at the Faculty of Agriculture of the Hebrew University of Jerusalem and worked in a nursery at Kibbutz Saad before earning her degree. A recipient of the 2023 Uri Zvi Greenberg Poetry Prize, she combines scientific expertise with a deep commitment to agriculture and society. Her scientific publications focus on the physiology and development of geophytes, fruit trees, ornamental plants, and medicinal crops.

Developing true F1 hybrid cannabis seeds required overcoming significant biological and technical obstacles.
“In hybrid seed production, parental lines must be highly stabilized,” Lazare explained. “In cannabis, as in many crops, these lines can suffer from inbreeding depression, reducing plant vigor, flowering performance, pollen production, and overall seed yield.”
Every stage of the process required extensive research and validation. The team had to create and maintain stable parental lines, manage reduced vigor, synchronize flowering cycles, produce and handle pollen, control pollination, and ensure the production of high-quality, uniform seeds.
“The biggest challenge was realizing that this was not simply a plant-breeding project,” she said. “Each step had to be developed, tested, and validated carefully.”
RCK is now among only four companies worldwide producing genuine F1 hybrid cannabis seeds. Notably, one of those companies has signed an agreement with RCK for seed production, highlighting international recognition of the Israeli firm's expertise.
Consistency for Medical Cannabis Producers
The company's goal is not to increase genetic variability but rather to provide growers with the consistency traditionally associated with cloned plants while benefiting from a seed-based production system.

"The objective was to give producers the reliability they expect from vegetative clones while using seeds", Lazare said. "This can support more standardized cultivation, more uniform plant development, and a more homogeneous raw material for medical cannabis products."

Such consistency is particularly important in the medical cannabis sector, where standardized active ingredients and predictable product quality are critical requirements.

Israel’s Leadership in Cannabis Research
Israel has long been recognized as a global leader in cannabis research, particularly in medical, biochemical, and pharmaceutical applications. According to Lazare, however, maintaining this leadership will require addressing regulatory challenges.
"The regulatory framework surrounding cannabis is complex", she noted. "While regulation is necessary, it also makes research slower, more expensive, and more difficult to conduct."
She believes Israel can remain a world leader if it continues to support rigorous scientific research while reducing unnecessary bureaucratic barriers.
“If Israel succeeds in supporting high-quality research while streamlining unnecessary regulatory hurdles, it can remain a global leader not only in medical and pharmaceutical cannabis research but also in the plant sciences and agricultural technologies that underpin the industry,” she said.
RCK’s studies have been conducted in collaboration with leading Israeli research institutions, including the Volcani Institute and Ben-Gurion University of the Negev. Additional scientific papers are currently undergoing peer review.
Building Resilience in the Western Negev
The company’s success comes against the backdrop of ongoing challenges faced by communities in Israel’s western Negev following the October 7 attacks. During the war, RCK experienced staff evacuations, reserve-duty mobilizations, canceled contracts, and financial difficulties.
Yet the company views innovation as an essential component of regional recovery.
“In this reality, agriculture is much more than an economic sector,” Lazare said. “It is one of the ways communities remain connected to their land, their identity, and their future.”

She argues that technology can help farms become more efficient, resilient, and less dependent on vulnerable labor systems and infrastructure. Advances in water efficiency, automation, crop monitoring, protected cultivation, and data-driven decision-making can help farmers navigate uncertainty.
“Agriculture teaches continuity,” she concluded. “You plant, you care, you wait, you repair, and you begin again. In the western Negev, this is not a metaphor. It is everyday life.”
As RCK prepares to demonstrate the commercial value of its first hybrid cannabis varieties, the company’s breakthrough may not only transform medical cannabis production but also serve as a symbol of innovation and resilience emerging from one of Israel’s most challenging regions.
