Characteristics of parents used for creating new quince populations
| Parents | Characteristics |
|---|---|
| ‘Viduja’ (KVD1) | Early flowering, high yield, fruit production on short branches (spore), dwarf, small to medium fruit, sweet and low astringency fruit, favorable edible quality, relative tolerance to fire blight |
| KVD2 | Early flowering, high yield, fruit production on short branches (spore), medium to large fruit, relatively good edible quality, longer storage period than ‘Viduja’, more canopy width and tree height than others |
| KVD4 | Early flowering, high yield, fruit production on short branches (spore), dwarf, medium to large fruit, sour fruit, high leaf phenol content, higher catalase, and peroxidase activity, chlorophyll content in leaves as well as longer storage period than others |
