Abstract
We analyzed the correlation among fruit bearing branch (FBB) and shoot and fruit characteristics in order to select the length of FBB suitable for producing high-quality fruits of 'Soomee', a peach tree developed in Korea. The length and diameter of FBB were 26.1 cm and 6.1 mm, respectively, shoot and leaf number per FBB were 3.2 and 38.6, respectively. Of these, the coefficient of variation was very high in the shoots and leaf number. The average weight and soluble solid content (SSC) of fruit were 298.6 g and 12.2 Brix, respectively, and coefficient of variation of the fruit weight was 18.0 %, which was higher than that of SSC. As the FBB of 10-20 cm and 20-30 cm length per tree were 27.1 % and 25.4 %, respectively, the sum of short and middle FBB frequency per tree was more than 50 %. Fruits of 250-350 g and 11.0-13.0 Brix per tree were distributed in 68.6 % and 74.0 %, respectively. As a result of correlation analysis, fruit weight and shoot number were affected by the length of FBB. In particular, length of FBB showed the relation of fruit weight with $y=-0.0482x^2+2.4512x+277.36$. As a result, the length of FBB that can maximize fruit weight was analyzed as 25.4 cm. Therefore, in the filed, the suitable FBB for producing 'Soomee' peach is estimated to be about 20-30 cm.
