A genetic analysis was conducted to study fruit color，lycopene content，chlorophyll content and
carotene content of the genetic populations（P₁，P₂，F₁，BC₁，BC₂ and F₂）generated by crossing green fruit
tomato inbred line‘Lyuying’and orange fruit tomato inbred line‘Jinzhu No.1’．The result showed that there was
no significant differences in fruit color of F₁ generation groups．However there were significant differences in pigment
content of F₁ generation groups，indicating fruit color was controlled by nuclear gene，while genetic of pigments
content in F₁ was not only controlled by nuclear gene，but also there existed some cytoplasm effects．The result of
analyzing by multiple generation conjoint showed that the genetics of tomato fruit color between green and orange
were accord with the pattern of MX2-A-AD．The major gene heritability and the polygene heritability in BC₁，BC₂
and F₂ was 73.42%，78.25%，61.41% and 22.87%，15.35%，34.94%，respectively．The genetics of chlorophyll
content was accord with MX1-AEND-AD．The major gene heritability and the polygene heritability in BC₁，
BC₂ and F₂ was 0，1.73%，0.65% and 45.47%，0，37.82%，respectively．The genetics of lycopene content，
as with genetics of carotene content，was accord with MX2-ADI-AD．The major gene heritability of lycopene
content and carotene content in BC₁，BC₂ and F₂ was 75.74%，1.79%，84.26% and 61.53%，87.21%，81.05%，
respectively．And the polygene heritability of them was 20.32%，74.12%，12.68% and 0.68%，0，0，
respectively．It indicated that the major gene heritability of lycopene content and carotene content was stronger．
