The researchers studied eight different types of local apples in Croatia to see which ones had the best quality. They looked at things like fruit size, firmness, sweetness, and taste. They found that the 'Majdofi ja' and 'Kardinal' apples were the most promising because they scored the highest in taste and overall impression. The 'Slastica' apple was the sweetest, while the 'Križara' apple was the least juicy. Overall, more research is needed to fully understand how these apples compare to others in different growing conditions.
