Taking dome eggplant and apex eggplant as parents,this study built 6 generations colony( P1,
P2,F1,BC1P1,BC1P2,F2),and planted them in spring open fields and autumn greenhouse as 2 crops for
rotation,respectively.The paper collect the apex shape data of eggplant fruit by ocular estimate method and
Tomato Analyzer software analysis method,and applied multiple generation combination analysis method on plant
quantitative trait major gene + multiple gene hybrid genetic model to carry out genetic analysis on eggplant fruit
apex shape.The results showed that both ocular estimate and software methods could be used to describe the
eggplant fruit apex shape.We found that the AIC value calculated by Tomato Analyzer software analysis method
for eggplant fruit apex shape data had good integrity,the number of significant statistics in adaptive detection was
less,the measurement on data of eggplant fruit apex shape was more accurate.Thus,Tomato Analyzer software
analysis method was more suitable for collecting characters of eggplant frnit apex shape.The characters of eggplant
fruit apex shape were quantitative trait,controlled by 2 pairs of additive-dominant-epistasis major genes,and
also influenced by environmental conditions.In the isolated population,the genetic rate of major gene of F2
population was high and stability was good.The genetic rate of major gene was over 72%.So,it is suitable to
carry out selection on fruit apex shape traits among F2 colony during breeding process.
