芒果种质资源果实重要经济性状多样性分析

对南亚热带作物研究所芒果种质资源圃内的芒果栽培品种的果实内、外的主要经济性状进行了鉴定评价.结果表明,在芒果的果实大小、果实形状、果皮颜色、可溶性固形物、可滴定酸、维生素C含量、可食率、果肉质地、果肉颜色、纤维、香味等方面均存在丰富的遗传多样性.在丰富的遗传多样性中,具有小果型、椭圆形（包括长椭圆、宽椭圆形）、质地中等细滑、清香等性状的品种较多.

Study on Diversity of Important Economic Traits of Mango Fruits in the Mango Gene Pool

An experiment was carried out to identify and evaluate the internal and external important economic traits of mango fruits in the Mango Gene Pool at th e South Subtropical Crops Research Institute, Zhangjiang, Guangdong Province, Ch ina. The results showed that rich genetic diversities existed in mango fruit cha racters such as fruit size, fruit shape, peel color, soluble solids, titratable acids, vitamin C, flesh percentage, pulp texture, pulp color, fibre and aroma. C ultivars with the characters such as small fruit size, elliptic (oblong elliptic and wide elliptic) shape, medium tender texture, light aroma, etc had a higher percentage in the rich genetic diversities of germplasm collected.
