Abstract:

Abstract：10 index for major biological traits i.e. tree bough and trunk angle; leaf length, width; inflorescence length, width, bisexual flower and male flower diameter; fruit length, width;single fruit weight were used to evaluate the main mango germplasm. Among 10 index, abundant biologic diversity was found and classification were carried out using 12 index including the leaf index and fruit shape index. An applicable reference standard was assumed using specific data indicator and reference cultivars, which lay a certain foundation for the system evaluation of mango germplasm resources.
