“长红”是由“红玉”作母本,“鸡冠”作父本杂交而成的。一九五四年选为优良品系,一九七○年育成、定名。多年实践证明,“长红”产量高,抗逆性强,较耐寒。果实极耐贮藏,在一般石灰窖中可贮藏至第二年五月份,最佳食用期为三、四月份。贮藏期间不得“红玉”的班点病。 “Red” is the “red jade” as the mother, “cockscomb” as the father of the hybrid made. Selected as a fine line in 1954, bred in 1970, named. Years of practice has proved that “long red” high yield, strong resistance, more cold. The fruit is extremely resistant to storage and can be stored in general lime cellars until May of the following year. The best eating period is March and April. During storage may not “ruby” shift point disease.
