Abstract: Using six high generation self-hybrid varieties with obvious differences to combine seven hybrid generation combinations.Relationship of agronomic characteristics of F1 hybrid generation such as the skin colour,tumour shape and the first female flower position of the main plant,female flower rate,fruit length,diameter,and their parents were observed.Results showed that no matter hybrid in positive or negative way,the skin colour of F1 balsam pear was mediated between their parents or trended to the light colour;The shape of F1 balsam pear was also between their parents;hybridization of tip tumour and round tumour in positive and negative way,F1 hybrid generation occured tip tumour,showed obvious tip tumour heredity;to F1 hybrid generation,the first female flower position of the main plant majority was mostly mediated between their parents,minority was lower than their parents;the female flower rate within thirty-five nodes of the main plant was between their parents,had a tendency to low female flower rate.hybridization of long shape and short shape fruits in positive and negative way,F1 hybrid generation are all long shape,showed obvious long shape pear heredity;hybrid ization of diameter and flesh in positive and negative way,the diameter and flesh of F1 hybrid generation are almost between the parents,and had tendency to the parents with large value.
