“…Apricot is an important fruit crop for the southern and western regions of Romania with a long tradition of cultivation (Bălan et al, 2008). Several breeding programs are active in Europe (Asma, 2012 (Gouble et al, 2020), field trials are essential and the results over few testing years need to be used when the introduction of a new cultivar is decided (Stănică et al, 2010;Stănică and Eremia, 2014;Tabakov and Yordanov, 2012;Zaman et al, 2018). In fruit trees, the field performances of a new cultivar, regarding the tree vigour, growth, yield and fruit quality, besides its genetic heritage, are essentially influenced by the rootstock (Duval et al, 2012;Krška et al, 2012;Tabakov and Yordanov, 2012), planting system and tree canopy (Stănică et al, 2012;Matei et al, 2013;Stănică and Eremia, 2014;Negru, 2019;Negru and Peșteanu, 2019).…”
