Abstract
To investigate the optimal size of fruit bearing branches (FBBs) of 'Kawanakajima Hakuto' peach (Prunus persica Batsch) for production of high quality fruits, we evaluated shoot growth and fruit characteristics relative to FBB direction and thickness. FBB diameter, shoot length, fruit weight, and soluble solids content (SSC) averaged 6.9 mm, 32.6 cm, 333.6 g, and $11.2^{\circ}Brix$, respectively. Coefficients of variation of FBB diameter and shoot length were high as 35.8% and 75.3%. The highest frequency values revealed that 76.4% of FBBs had a diameter below 9.0 mm, 70.0% of shoot lengths were less than 40 cm, 24.8% of fruits were 310-340 g, and 66.9% of SSCs were $10.5-12.5^{\circ}Brix$. Shoot length and SSC were significantly affected by FBB diameter without direction, and fruit weight was significantly affected by interaction of FBB diameter and direction. There was a negative correlation ($r^2=0.094^*$) of FBB diameter and fruit weight with upward FBB directions, whereas FBB diameter and fruit weight were positively correlated ($r^2=0.246^{**}$) with downward FBB direction. With thick FBB diameter, shoot length, and SSC were significantly increased, but fruit weight was decreased. Therefore, downward FBBs below 9.0 mm in thickness are suitable for producing high-quality fruits of 'Kawanakajima Hakuto' peach.
