Development and validation of a molecular marker for red-flesh early selection in pear
Due to their high concentration of bioactive substances, particularly anthocyanins, red-fleshed fruits are becoming more and more well-liked by customers worldwide.
The genetic control of the red-fleshed fruit feature has been investigated in a number of fruit species, such us apple, peach, plum, sweet cherry, and others.
Even though red-fleshed pears have been known for centuries, very little research has been done on this characteristic.
Nowadays several pear breeding programs have included the red flesh as a target of selection, and in this scenario the availability of markers for an early selection is advisable.
Therefore, the general aim of this study was to find tools for boosting the ongoing breeding programs for red-fleshed pears.
An SSR marker has been developed after QTL analysis on a crossing population segregating for the trait (‘Cocomerina Precoce’ × ‘Carmen’). Furthermore, the marker efficiency was also confirmed on 11 additional crossing populations derived from other red-fleshed germplasm of different origins.
The marker developed exhibited extremely high accuracy in fruit flesh color prediction.
