The fruits are oblate and have red skin; the flesh is yellow, sour and sweet. The average mass of a fruit is 6.74 g, and a fruit has a half freestone. The content of soluble solids reaches 10.9%, and total sugar and total acid content are 8.20% and 1.81% respectively, so the ratio of total sugar content to total acid content is 4.53; the edible rate is up to 94.51%. In the flesh, calcium, iron, zinc, and vitamin C content are 219.7, 4.4, 1.09, and 182 mg/kg respectively. Fruits ripen in late July in Beijing, and the development period of fruits is 96-101 d. Fruits can be kept for 3-5 d at room temperature, about 20 d in cold storage, and one year under freezing conditions. It can be cultivated in Beijing, flowers and fruits in the next year, with strong yielding ability.展开更多

It was presumed that they had intermediate karyotype between the parents, and formed sperms with heteroploidy resulting from the incomplete pairing of homologous chromosomes in meiosis. Due to the abundance of species and the ease of artificial fertilization, the study of the factor of the hybrid sterility in bitterlings would lead to the clarification of the mechanism about species differentiation and karyotype differentiation, and also to developing a new variety.展开更多
