Abstract:
‘Guanyu’ was a new variety of pear tree with high quality multiresistance and fresh food processing in middle and late maturity，artificially bred from the natural hybrid of ‘Whangkeumbae’ pear after 16 years.Through DNA genetic identification，it was confirmed that its male parent was ‘Huangguan’，which was a sister line of ‘Jinguang’.‘Guanyu’ is a deciduous tree with a moderate tree vigor，moderate germination and branching power.The annual branches are brownish brown，with small lenticels and long oval shapes.The flower buds are mainly terminal，and the short fruit branches bear fruit，easily forming axillary flower buds.The fruit is round，with a fruit shape index of 0.85，light yellow，few fruit spots，thin and smooth pericarp，and an extremely beautiful appearance.The flesh is white，the core is small，the flesh is fine and crisp，without stone cells，and is sweet and refreshing.The average single fruit weight is 235 g，soluble solids are 12% to 14%，titratable acid is 0.19%，and fruit hardness is 7.5 kg?cm-2.This variety has strong resistance to cold，scab，and browning，making it suitable for drying and juicing.In Shijiazhuang area，the fruit matures in late August，with a fruit growth period of about 147 days.
