Wild Tomato Genome will Benefit Domesticated Cousins

A team of researchers has assembled a reference genome for Solanum lycopersicoides, a wild relative of the cultivated tomato, and developed web-based tools to help plant researchers and breeders improve the crop. Solanum lycopersicoides (S. lycopersicoides) harbors a gene making the plant resistant to a particular strain of bacterial speck disease. The gene could be introduced into cultivated tomatoes to protect …

Moonshadow Joins ‘Galaxy’ of Colorful Tomatoes

Moonshadow, a deeply pigmented purplish-red, oblong tomato, was bred using traditional crossing methods and derived from a cross between a black grape tomato and a high-flavor orange grape tomato. It is now available for pre-order, for spring 2022 planting, from High Mowing Organic Seeds. Moonshadow is the sixth variety in the Galaxy Suite, a colorful, multishaped group of medley grape tomatoes bred by Phillip Griffiths, associate professor in the …

Tomato Trade with Mexico could Cost US Growers $250M a year

As Mexico increases tomato exports across the world, including to the United States, prices plummet for American growers. That practice could cost American growers as much as $252 million per year — or 27% in revenue — if imports from Mexico increase by 50% in coming years, based on historical trends, new University of Florida research shows. That’s a huge …

California Processing Tomato Crop Forecast Below May’s Expectation

Contracted production for California processing tomatoes is forecast at 11.1 million tons, averaging 48.9 tons per acre. The current production forecast is 1.9% below last year’s contracted production, and 4.3% below the May forecast. The projected harvested acreage of tomatoes grown under contract is 227,000 acres, which 0.4% lower than in 2020. Drought concerns impacted planting decisions for the 2021 …

The Threat of Branched Broomrape for California Processing Tomato

Branched broomrape (Phelipanche ramosa), a parasitic weed that was the focus of a $1.5 million eradication effort four decades ago in California, has recently re-emerged in tomato fields in several Central Valley counties. Processing tomatoes are important to the California agricultural economy; the state produced over 90% of the 12 million tons of tomatoes grown in the United States in …

NASA Funds Tiny Tomatoes for Vertical Farming on Earth and Space

Urban agriculture offers many benefits for food production but often has higher costs relative to traditional farming and is limited to only a few crops. By 2050, there will be nine billion people on the planet, but arable land is decreasing. Global food production will need to double to meet food needs, though climate change complicates the problem more. Robert …
