| 【Objective】Botanical characteristics and fruit economic characters of 11 abiu germplasm resources
were identified in order to provide a reference basis for the identification and superior variety breeding of abiu germplasm
resources.【Method】The botanical characteristics of abiu were observed in the field. 16 quality indexes of the fruits were
measured and a correlation analysis was conducted.【Result】The experimental germplasm resources of abiu had great
differences in botanical characteristics and fruit economic characters, showing rich genetic diversity and different degrees
of correlation among fruit indexes. The comprehensive analysis showed that HJG151 grew vigorously, the shape of mature
fruit was perfectly round and the pericarp color was golden, with an average single fruit weight of 276.47 g and an edible rate
of 67.64%. The fruit economic characters was superior and the overall character indexes were basically consistent. Vitamin
C and protopectin content of HJG134 were the highest, which were 0.50 mg/g and 0.98% respectively. It could be used as
an alternative germplasm resource with some excellent character indexes. 【Conclusion】2 excellent germplasms werescreened out, which provides a theoretical basis for the innovative utilization of abiu germplasm resources and the cultivation of
excellent varieties. |
