Genetic Analysis of Plant Height and Main Stem Length in Chili Pepper
This study investigates the genetic mechanisms of plant height and main stem length in chili pepper.Four generations of genetic populations,namely P1,P2,F1,and F2,were developled using the dwarf accession C152 as the maternal parent and the tall material A37 as the paternal parent.Ge-netic analysis was conducted using a mixed inheritance model that integrates major gene and polygenic effects.The results demonstrated that the inheritance of plant height in chili pepper was regulated by two pairs of additive major genes along with additive-dominant polygenes.The additive effect value of the first pair of major genes was 32.803 8,and the additive effect value of the second pair of major genes was 19.653 5,and the heritability of the major gene was 91.83％.In contrast,the main stem length was regulated by two equal additive major genes plus additive dominant polygenes,with an ad-ditive effect value of-4.052 4 and a major gene heritability of 55.69％.
