Genetic analysis of floral traits and fruit traits in pepper (Capsicum annuum L.).

To realize the variations of the pepper floral traits,fruit traits and their relationship,genetic analysis and correlation analysis of 12 traits were conducted in 29 accessions from 4 varieties in Capsicum annuum L..The results showed that the 12 traits had high genetic diversity among the 4 varieties,and the coefficient of variation(CV) of 12 phenotypic traits ranged from 13.10%(flower length) to 86.80%(fruit weight),and heritability ranged from 30.81%(fruit length) to 88.73%(ovary diameter).The 8 floral traits had close correlation with 4 fruit traits.Factor analysis indicated that 12 traits of the accessions might be simplified to 3 independent trait groups controlled by 3 main factors.Factor 1 was a diameter /weight factor;Factor 2 was considered to control the length of flower and fruit;Factor 3 was a shape index factor.The accumulative contribution rate of the 3 major factors to tota1 variation accounted for 84.83%,maintaining most of information of 12 traits.
