&Iota:n an effort to create walnut cultivars (Juglans regia) with high productivity, fruit quality and lateral bearing, a new cultivar, named &ldquo:Leto&rdquo:, was created by the cross &ldquo:Gustine&rdquo: ×: &ldquo:Pedro&rdquo:. Its main phenological and pomological characteristics were assessed according to the criteria of IPGR (1994) and UPOV-TG/125/6 (1999), for 10 consecutive years and compared with its maternal cultivars and &ldquo:Chandler&rdquo:. Observations showed that &ldquo:Leto&rdquo: has high lateral bearing habit (90%) and presents satisfactory yield at the full production age. The tree size is smaller than that of its parents and &ldquo:Chandler&rdquo:, female flowers bloom from 11 to 22 of April and male from 3 to 6 of April. &ldquo:Leto&rdquo: nuts are harvested at the end of September, present easy hull dehiscence and high kernel percentage. Other positive nut characteristics of &ldquo:Leto&rdquo: are light kernel color, well kernel filling and easy removal of the kernel halves. &ldquo:Leto&rdquo: is a mid-early cultivar of great interest due to its high- quality nuts, suitable for dense plantings, in regions where the last spring frosts occur in late March to early April, thus, making it a promising cultivar for Greece, but also for other regions with similar geomorphological and climatic conditions.
