Breeding of a new high-quality passion fruit cultivar Jindubaixiang No. 3

Abstract: Jindubaixiang No. 3 is a new fresh edible passion fruit cultivar derived from the cross between Tainong No. 1 and the yellow passion fruit (Passiflora edulis f. flavicarpa). The shape of fruit is slightly oblate, and the average weight of single fruit is 98.56 g. The rind of summer-ripened t and winter-ripened fruit is purplish pink and purplish red, respectively. White dots are densely distributed on the fruit. The peel of the fruit is hard. The flesh of fruit is yellow to orange-yellow. By the determination of fruit juice, the soluble solids content is 17.6%, the total sugar content is 14.04 g · 100 g^-1 , the titratable acid content is 1.89%, the vitamin C content is 12.50 mg · 100 g^-1 , the edible rate is 60.40%, and the juice rate is 51.94%. Ripe fruits are heavy with a lot of juice, with refreshing sweet taste and fragrant “honey peach”smell. Jindubaixiang No. 3 cultivar has medium growth vigor, good self-compatibility, and high and stable yield. The annual average yield per plant is 18.53 kg and the annual average yield reaches 2 038.3 kg per 666.7 m² . In Nanning, Guangxi, the fruit ripening period is July, and from January to March of the next year. The fruit growth period is 80-130 d. The cold tolerance of Jindubaixiang No. 3 is stronger than the yellow passion fruit. The fruit can be stored at room temperature for 7-10 d without wrinkled skin. The storage period is 10-15 d in room temperature storage and 30 d in cold storage. Jindubaixiang No. 3 is suitable for planting in Guangxi, Guangdong, Hainan, Yunnan, Guizhou and other areas suitable for planting passion fruit. The net-house cultivation mode should be preferentially selected to obtain high yield and good quality.
