‘Silistrenska ranna’ – Bulgarian cultivar used in apricot breeding program

Phenotypic diversity of apricot cultivars derived from of Shalakh variety

“…The best inheritability of the cultivars of the characteristics of the Shalakh, in addition to selectively directed selections (for consistency, taste, adherence of stone to flesh, bitterness), were founded for such diagnostic traits as symmetry of fruit and stone (100 %), form hole shape of stone (100%), shape of stone apex (100 %), keel character (100 %), blotchness (88.9 %), shape of stone base (88.9 %), thickness of stone (77.8 %), lateral ribs type (77.8 %). It is known that yellow skin and the color of flesh of fruit dominate over orange [11]. The prevailing color of skin is orange and yellow-orange color of flesh as for Shalakh cultivars.…”

“…One of the most important attributes in creating new varieties are the characteristics of the fruit and stone which determines the commercial value for producers and attractiveness for the consumers [11].…”
