摘要:

以杧果‘金煌’ב热农1号’的F1代54个单株为材料,对其果实性状进行观测,并对单果质量等9个数量性状进行了遗传分析,对30个数量性状和描述性状进行了Shannon-Weaver多样性和主成分分析。结果表明,9个数量性状(单果质量、果实纵径、横径、侧径、果形指数、可溶性固形物、可食率、果核长度和果核质量)在后代中的遗传符合正态或偏正态分布,变异系数在7.98% ~ 41.73%之间,多样性指数在1.65 ~ 2.04之间,遗传传递力在84.74% ~ 117.00%之间,果实大小等性状呈趋中变异趋势,可溶性固形物呈超亲遗传趋势。21个描述性状的多样性指数在0.16 ~ 1.48之间。主成分分析发现前10个主成分的累积贡献率为75.19%,并筛选出单果质量、抗性、果形指数、果皮光滑度、果肉纤维长度、果核表面特征、果实风味、可溶性固形物、胚类型和果肉颜色作为评价杂交后代果实的主要性状。基于观测数据建立了杧果杂交后代果实性状综合评价模型,并利用该方法结合田间观察和实际观测结果筛选出8个优异的单株。

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.
