Abstract Hybrid combinations of cherry tomato（Lycopersicon esculentum Mill. var. cerasiforme
Alef.）were made by round black brown inbred line Z1，prolate pear-shaped reddish black inbred
line Z2，the round red，oblate pale pinkish red，oval orange yellow and round yellow inbred lines．
These inbred lines were taken as experimental material and formed incomplete diallel cross formulated
combinations．Through studying the agronomic characters of F1，the quality characteristics and disease
resistance，we explored the quality improvement of black cherry tomato germplasm，and the utilization of
prolate pear-shaped fruit，in order to provide references for the innovative usage of special fruit color or
shape of tomato germplasm in the future．The results showed that the black color of cherry tomato fruit is
recessive trait．Parental relative traits（ round fruit or oblate fruit×prolate pear-shaped fruit，long oval
fruit×prolate pear-shaped fruit），their F1 fruit shape are elliptic and long finger shape，respectively．
