Variety description
10 August 2026
The Spoppo variety was obtained by crossing HK35 and ATCC 58937 lines followed by selection. The key feature is a genetic mutation responsible for the absence of spores, which reduces the risk of allergic reactions in workers during cultivation.
Despite the genetic changes, the fruit bodies retain standard morphology and an attractive commercial appearance. The variety is viable, suitable for industrial cultivation, and demonstrates the ability to withstand low temperatures during the cultivation period.
Special molecular tests have been developed to identify this variety, allowing it to be distinguished from other commercial Pleurotus strains.
