Estimation of the genetic parameters of boron and sorbitol concentration in fruit from a pear breeding population, and investigation of the relationship between these traits on the occurrence of flesh spot decay
Pears (Pyrus spp.) are among the oldest crops grown worldwide. They are cultivated in all temperate regions and world production is second only to apples among deciduous tree fruits. Flesh spot decay (FSD) is one of the most important physiological disorders of Asian pears. The causes of this …
