LDS: Leaf drying score based on visual evaluation of the dried area of top leaves at 1  week after flowering. 0: no dried leaves; 1: fewer than 5%; 2: 5–10%; 3: 10–15%; 4: 15–20%; 5: >20%. Scoring was performed at noon when the LDS of neighboring control plants was more than 4. The score for each family is the average performance of the 16 plants in the middle of each plot.
