Tomato miniplum Miele F1, a real aid to face ToBRFV

Biotic adversities invading the tomato growing landscape are numerous and frequent. For the past couple of years Tomato Brown Rugose Fruit Virus (ToBRFV) (discovered in Israel – 2014 and first isolated in Jordan, -2015) belonging to the Tobamovirus genus, has been present.

The virus high contagiousness combined with the rapid spread over long distances and the impossibility to market infected fruits make it one of the most harmful pathogens in recent years because of the great economic impact it brought into the market, which is increasingly emerging in Sicily and Europe.

Climatic conditions, like light and temperature, can have some influence on the showing of symptoms that seem to evolve faster during spring-summer cycles. Symptoms occur through mosaic discolorations, deformation and necrosis on young leaves and vegetative apices, necrosis on sepals, discolorations and necrosis on young fruits.

Tomato Brown Rugose Fruit Virus is mechanically transmissible via infected seed, through cultivation practices, tools, equipment and circulating soil solution. Weed species include Petunia hybrida or Solanum nigrum, which can become the cause of the virus spread.

Even if resistant varieties have not been introduced on the market yet, there are some commercial varieties which, according to field observations, would appear to have an intermediate resistance (IR) to Tomato Brown Rugose Fruit Virus, showing a milder symptomatology or even no symptoms at all, as it is for tomato mini plum Miele F1.

The variety belonging to the Sicilian company Fenix, which is well-known to be a high-quality product thanks to the excellent characteristics constantly observed over time like very high sweetness degree and exceptional tolerance to cold and fruit cracking, is proving to be much less susceptible to the pathogen than many other similar ones.

This mini plum variety (Miele) has proved to be completely asymptomatic in many cultivations, despite being exposed to normal growing conditions and more or less intense inoculum doses. Therefore, this variety belongs to the so-called symptomless carriers because the viral sequences can be present or even multiply in the plant without causing an evident symptomatology.

Even though we still do not have scientifically certain proofs about this effective intermediate resistance because specific molecular markers are not yet available on the market, it is difficult to consider the evidence collected in the field as the result of simple and mere coincidences, considering also the diversity of conditions and the important number of cases in which the variety has already shown a real absence of symptoms.

Therefore, a plant with intermediate resistance can moderately limit the growth and development of the virus despite being attacked by it because resistance levels can vary without being mutually exclusive.

Fenix does not exclude the possibility to carry on molecular analyses to evaluate genetic resistance when this is possible, so that we can scientifically confirm the results that the variety is showing day after day in the field.

ToBRFV is becoming more and more evident as an epidemic pathogen, especially in Sicily and Europe; it is important to act carefully to limit the spread of the virus through preventive actions such as the use of virus-free and certified seeds and seedlings, crop rotations with non-host species, sanitization of cultivation environments, clothing used for work, tools and the removal of crop residues and weeds.

Choosing to cultivate certain varieties such as Miele F1, by implementing agronomic practices that limit as much as possible the stress that is linked to the cultivation, it gives the farmer a valuable tool to ensure continuity and excellent quality that characterize the Italian horticultural scene.

Israel announces creation of global seed company

Two Israeli seed producers, Nirit Seeds and TomaTech, have joined forces to create Israel’s largest vegetable seed company. This synergy will enable unique seed breeding research and development that will accelerate the company’s growth in the international seed markets.

Upon completion of the merger, the company will have more than 80 employees worldwide, including molecular biologists, breeders, agronomists, and others.
The company will improve its breeding activities in Israel, Spain, Mexico and Italy, as well as significantly expand its representation in the Netherlands and North America, with a particular focus on growing vegetables in high-tech greenhouses.

Nirit Seeds is one of the most successful internationally traded tomato and pepper seed producers, investing in the development of revolutionary genetic technologies. TomaTech is one of the leading tomato seed companies in Israel, developing premium varieties, including those resistant to the dangerous Tomato Brown Ruffle Virus (ToBRFV).

The production of crop seeds is one of the most advanced and high-tech sectors in Israel. According to the Seed Department of the Federation of Israel Chambers of Commerce, seed exports currently generate $200 million in annual revenue. There are about 25 large and medium-sized companies in the local industry.

For reference. According to market research, the global vegetable seed industry is valued at $8 billion a year and is growing at a CAGR of 8%.

Karachay-Cherkessia became one of the leaders in the production of greenhouse vegetables at the end of 2021

fdQAAAABJRU5ErkJggg==

Greenhouse vegetable production in 2021 reached a record 1.4 million tonnes. According to the Ministry of Agriculture of the Russian Federation, the leaders among the regions in this segment are the Karachay-Cherkess Republic, Lipetsk, Moscow, Kaluga, Volgograd, Novosibirsk, Saratov, Chelyabinsk regions, Krasnodar and Stavropol Territories, the Republics of Bashkortostan and Tatarstan. These regions account for more than 60% of the total production in the country. The intensive development of greenhouse projects in our country helps to provide Russians with fresh vegetables all year round. Last year, the harvest in winter greenhouses updated the 2020 record – more than 1.4 million tons of products were received. Including the production of cucumbers amounted to at least 830 thousand tons, and tomatoes – 590 thousand tons. It is expected that by 2025 the volume of vegetable production in year-round greenhouses will be at least 1.6 million tons of vegetables.
