Study of chilli genetics could lead to greater variety on our plates

Scientists investigating the genetics of chilli pepper species have discovered a whole host of new chilli hybrids that can be grown by crossing domesticated peppers with their wild cousins. This will allow plant breeders to create new varieties that have better disease resistance and could increase productivity.

There are 35 species of pepper in the Capsicum family, including five domesticated species. The most well-known of these is C. annuum, which includes several varieties with widely differing shapes and tastes, including bell peppers, jalapeños, New Mexico chiles, and cayenne peppers.

The team of scientists from the World Vegetable Center in Taiwan investigated the genetic relatedness between 38 samples of 15 species of wild and domesticated peppers collected from locations around the world. Their findings, published in the journal, Plos one, found that breeding compatibility between species was not necessarily connected to how closely related they were to each other.

Lead author of the study, Catherine Parry, collected the data whilst on a six-month work placement at the World Vegetable Center as part of her undergraduate degree in Biology at the University of Bath.

New flavours
She said: “The main differences between peppers that are grown for culinary purposes and their wild counterparts are that the wild species have much smaller fruits and leaves. However, we have large gaps in our understanding of the wild relatives of the Capsicum family. Many of the wild species have better disease resistance and so our findings could be valuable for identifying candidates for future breeding programmes, potentially increasing productivity for food producers and maybe even creating some new flavours to explore too!”

The World Vegetable Center, Taiwan, holds the largest collection of Capsicum genetic material globally. Dr Derek Barchenger, from the World Vegetable Center and second author on the study, said: “Unlike other crops in Solanaceae, the use of wild relatives in pepper/chilli/chile pepper breeding programs is extremely limited.

“In fact the phylogeny of Capsicum is still not completely resolved. There are many important abiotic and biotic stresses to which we lack sources of resistance and tolerance. Therefore, we are interested in exploring the wild relatives of Capsicum to identity resistant sources to incorporate into our breeding program.”

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.
