Abstract:

Fifty-four individuals of F1 population from a cross‘Chinhuang’(female)בRenong 1’(male)were chosen as materials and 30 fruit traits were evaluated in mango. The genetic analysis were studied for nine quantitative traits including fruit weight,fruit length,width,thickness,fruit shape index, soluble solids,editable rate,stone length and stone weight. The Shannon-Weaver diversity index and principal component analysis of nine quantitative traits and 21 descriptive traits were carried out by SPSS19.0 software. The results showed that the phenotypic diversity of nine quantitative traits in the evaluated progenies were normal distribution or partial normal distribution,and its coefficient of variation ranged from 7.98% to 41.73%,the Shannon-Weaver diversity index(H’)of nine quantitative characters ranged from 1.65 to 2.04 indicating that the fruit of progenies was rich in diversity of quantitative characters,its heritability ranged from 84.74% to 117.00%,eight traits including fruit weight showed a trend of medium variation,while total soluble solids showed a trend of super parent inheritance. The diversity index of 21 descriptive characters ranged from 0.16 to 1.48. Principal component analysis showed that 75.19% of cumulative contribution rate was explained by the first 10 principal components,and fruit weight,resistance,fruit shape index,skin smoothness,length of fiber in pulp,veins on stone,fruit flavor,total soluble solids,type of embryony and pulp color were selected as the main traits. A comprehensive evaluation model for fruit traits of progenies was also established,based on this method,combined with field and practical observation results,eight outstanding individuals were selected.
