Spinach (Spinacia oleracea L.) is a highly nutritious leafy vegetable and an economically important food crop. The wild species S. turkestanica Iljin tetrandra Steven ex M. Bieb. are inter-fertile with cultivated spinach constitute sources of novel characters to improve varieties, such as for their resistance pests diseases. Despite relevance in plant breeding, poorly represented genetic resources collections. Among the reasons these collection gaps difficulties propagating situ. Here we report on results collecting expeditions Central Asia Trans-Caucasus, which were organized by Dutch gene bank collaboration several breeding companies. Furthermore, also present efficient protocols situ regeneration species. These used successfully regenerate 66 36 samples from expeditions. new accessions fill up conserved can be exploitation crop improvement.
