PROMISING BREEDING FORMS OF MANDARIN (CITRUS RETICULATA BLAN. VAR. UNCHIU TAN.) AND THEIR QUALITATIVE DESCRIPTION

The paper presents a study of promising breeding forms of mandarin, including pomological characteristics and fruit quality assessment. It is established that breeding forms of mandarin in the average are as good as the regionalized cultivar ‘Kowano-Wase’, however, the breeding forms 99-2; 99-4; 99-8 differ from the control cultivar in their pomological indications – fetal weight 98.5–150 g; thin peel of fruits was recorded in hybrids 16-1; K-21; U18-1; high contents of sugars (9.50 % to 10.6 %) and dry matter (12–12.6 %) were recorded in the forms 99-2; 01-4; 16-1; 2-2; 2-8; 99-4; 99-8. Harmonious sugar-acid ratio (9.2–9.7 %) was marked in the forms: 2-2; 2-8; 99-2; 99-4; 99-8. Harmonious sugar-acid ratio (9.2–9.7 %) was marked in forms: 2-2; 2-8; 99-2; 99-4; 99-8. The recorded hybrid forms of mandarin are of great interest for further breeding work to create new cultivars.
