Abstract

Abstract: With classic genetics and the major gene plus polygene model of quantitative traits, a joint analysis of multi-generations from the cross between an extreme earliness inbred line ‘B₉₄₃₁ ’ and ‘Jilin Changjiao’was carried out to investigate the inheritance of the node of the first flower in pepper(Capsicum annuum L. ). The results showed that the node of the first flower in ‘B₉₄₃₁’was controlled by a recessive major gene and the inheritance of the node of the first flower fitted one major gene plus polygene model. Heritability values of the major genes of B₁, B₂ and F₂ population were estimated as 83.72% , 76.56% and 86.63% respectively, while those polygene were 10.96% , 18.58% and 7.94%.
