𝐀 𝐩𝐞𝐫𝐞𝐧𝐧𝐢𝐚𝐥, 𝐟𝐫𝐨𝐬𝐭-𝐫𝐞𝐬𝐢𝐬𝐭𝐚𝐧𝐭 𝐦𝐚𝐢𝐳𝐞 𝐢𝐬 𝐢𝐭 𝐩𝐨𝐬𝐬𝐢𝐛𝐥𝐞? 𝐀𝐛𝐬𝐨𝐥𝐮𝐭𝐞𝐥𝐲 𝐚𝐧𝐝 𝐈’𝐦 𝐰𝐨𝐫𝐤𝐢𝐧𝐠 𝐨𝐧 𝐢𝐭! Thanks to 𝑍𝑒𝑎 𝑑𝑖𝑝𝑙𝑜𝑝𝑒𝑟𝑒𝑛𝑛𝑖𝑠, an extremely rare wild species! It was only described in 1979, and is considered critically endangered in the wild. It is restricted to just a few small, isolated populations, confined to the Sierra de Manantlán in the state of Jalisco, Mexico. This maize species is perennial thanks to its rhizomes, and is capable of surviving light frosts! And although it belongs to the Luxuriantes section, which is distant from cultivated maize, they share the same ploidy level (2n = 20) and are interfertile! But above all, 𝑍𝑒𝑎 𝑑𝑖𝑝𝑙𝑜𝑝𝑒𝑟𝑒𝑛𝑛𝑖𝑠 is also interfertile with certain species of the genus 𝑇𝑟𝑖𝑝𝑠𝑎𝑐𝑢𝑚, and it can therefore be used as a genetic bridge between 𝑇𝑟𝑖𝑝𝑠𝑎𝑐𝑢𝑚 and cultivated maize! This therefore unlocks a access to an entirely new reservoir of genes for perenni...

𝐀 𝐩𝐞𝐫𝐞𝐧𝐧𝐢𝐚𝐥 𝐟𝐫𝐨𝐬𝐭-𝐫𝐞𝐬𝐢𝐬𝐭𝐚𝐧𝐭 𝐭𝐨𝐦𝐚𝐭𝐨 𝐢𝐬 𝐢𝐭 𝐩𝐨𝐬𝐬𝐢𝐛𝐥𝐞? 𝐘𝐞𝐬! 𝐀𝐧𝐝 𝐈’𝐦 𝐰𝐨𝐫𝐤𝐢𝐧𝐠 𝐨𝐧 𝐢𝐭! Thanks to the Peruvian tomato (𝑆𝑜𝑙𝑎𝑛𝑢𝑚 𝑝𝑒𝑟𝑢𝑣𝑖𝑎𝑛𝑢𝑚), a wild tomato species that is perennial and more or less frost-resistant! This species is very distant from the cultivated tomato, too distant to cross with it without resorting to sophisticated in-vitro embryo rescue techniques. At least, usually! Because I managed to obtain a very special and completely innovative line that is partially interfertile with the cultivated tomato and a hybrid line obtained with a red cherry tomato! I immediately saw the potential for a perennial, frost-resistant tomato! Because from 2015 to 2019, I had grown and selected another 𝑆. 𝑝𝑒𝑟𝑢𝑣𝑖𝑎𝑛𝑢𝑚 line that is just as exceptional, but this one for its very high frost resistance!  Nearly 100% of the plants were perennial and resistant to frosts down to -10°C! Their foliage dried out durin...

𝟏𝟗 𝐧𝐞𝐰 𝐬𝐞𝐱𝐮𝐚𝐥𝐥𝐲 𝐟𝐞𝐫𝐭𝐢𝐥𝐞 𝐠𝐚𝐫𝐥𝐢𝐜 𝐜𝐥𝐨𝐧𝐞𝐬 𝐟𝐫𝐨𝐦 𝐈𝐍𝐑𝐀𝐄, 𝐬𝐨𝐦𝐞 𝐨𝐟 𝐭𝐡𝐞𝐦 𝐚𝐫𝐞 𝐯𝐞𝐫𝐲 𝐩𝐫𝐨𝐦𝐢𝐬𝐢𝐧𝐠 𝐢𝐧 𝐭𝐞𝐫𝐦𝐬 𝐨𝐟 𝐬𝐞𝐱𝐮𝐚𝐥 𝐟𝐞𝐫𝐭𝐢𝐥𝐢𝐭𝐲! ____________________________________________ These clones were collected in the 1990s by Agri-Obtentions, a subsidiary of INRAE (French national institute for agricultural research). Various hybrids were produced as part of a program aimed at studying sexual reproduction in garlic and creating new genetic variability. In 2008, they were transferred to the BrACySol genetic resources bank of INRAE. Among them, 19 were entrusted to me last autumn, they are: MX2, MX4, MX5, J130, J184, J197, J211-19, J200-2, TA1, TA4. Some hybrids obtained between them: MX2 × J130, MX4 × J203, MX5 × J184, TP5 × J197. And some of the series: AS 01 5 1, AS 01 5 2, AS 01 5 3, AS 01 5 6, and AS 01 13 1. The MX clones originate from Mexico, the J from the Russian Federation, and the TA from Tajikistan. This year ...
