In order to clarify the change rules and inheritance of Vc content in pepper fruit,fruit Vc content in different pepper genotypes at different maturity levels,and adopted the joint segregation analysis method of major gene plus polygene for Vc content genetic analysis in red ripe fruits were studied. Results showed that the Vc content in the fruit of hot pepper genotypes was significantly higher than in sweet pepper genotypes. And in most varieties,significantly higher Vc content was found in ripe fruit tha...
