黑色/长梨形樱桃番茄种质的研究利用

以樱桃番茄黑褐色圆形自交系Z1、红黑色长梨形自交系Z2、红色圆形、浅粉红色扁圆形、
橙黄色长椭圆形和黄色圆形等自交系为试材，进行不完全双列杂交配制组合。通过对杂交组合后代的农艺
性状、品质特性和抗病性等的调查研究，探究黑色樱桃番茄种质品质改良和长梨形果形的利用，为今后特
殊果形果色番茄种质的创新利用提供参考。结果表明：樱桃番茄果色黑色性状为隐性性状；亲本为圆形果
或扁圆形果×长梨形果、长椭圆形果×长梨形果时，F₁ 果形分别是椭圆形与长指形。

Research and Utilization of Black/Prolate Pear-shaped Cherry TomatoGermplasm Resources

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．
