摘　　要：以09-16(‘晚熟香蕉’ב秋姬’)和‘幸运’为亲本的杂交组合F1代为试材,对果实13个经济性状进行遗传分析。结果表明,09-16和‘幸运’F1代早于亲本超亲个体和晚于亲本的低亲个体比例分别为9.21%和30.26%,晚熟杂种优势明显;评价果实大小指标均低于亲中值,果实大小趋向于小果;果实硬度呈偏向于软肉的连续变异;可溶性固形物、鲜食品质评价等级均出现较高比例超低亲个体分别为75.00%和31.58%,呈明显的衰退趋势,果实品质倾向于低亲父本遗传;果实风味以甜酸和酸甜为主;果实颜色紫红对红为优势遗传;果实形状趋圆遗传;果顶形状分离主要为圆凸(53.95%),其次为平(23.95%);果粉厚度趋薄遗传。In this study,The F1 segregation progenies of 09-16בFortune’crossing combination were used as materials.The phenotypes of 13 fruits characters were investigated to analyze the inheritance tendencies.The results showed that for the F1 generation,the proportions of earlier than and later than their parents individuals were 9.21%and 30.26%respectively,showing significant heterosis at late maturity.The evaluation of fruit size indicators were lower than the mid-parent values,with the fruit tending to be small.The fruit hardness showed a continuous variation in favor of soft pulp.Higher proportions of ultra-low individuals(75.00%and 31.58%respectively)were available in the evaluation of soluble solids and fresh food quality,indicating a significant trend of decline.The fruit quality tended to be inherited from low-parent paternal inheritance.The fruit taste was mainly sweet-sour and sour-sweet.The dominant color inherited was purplish red to red and the dominant fruit shape inherited tended to be round.The fruit apex separated was mainly of round convex shape(53.95%),followed by flat shape(23.95%).And the fruit powder inherited tended to be thin.
