This plans for improved currently seed export varieties has musk smell characteristics and increased varieties multiple characteristics,intends collection high yield,and large fruit,and tolerant transportation, and resistance of disease, and pulp color deep with functional trait of papaya strains, and cross with has breeding of owned strains hybrid, breeding fruit quality excellent, and fruit type neatly,and fruit heavy 1-3 kg, no strongly taste and tolerant of toleran and storage, with high nutrition value of new varieties, increased export seed of multiple, Promoting seed industry expanding the export or supply of agricultural enterprises to set up production bases abroad,  expanding local markets. The disease-resistant strains collected this year, after the virus be inoculated, most of the leaves appear serious symptom of PRSV, the fruit skin have ring spot or deformity, but some plant symptom is relatively slight, will further confirm the disease resistance.Collection of large fruit strains, fruit weight 2-4 kg, pulp thick,resistant to storage and transportation, but fruit setting is fewer.Small fruit strain with high sugar content and high yield were used to improve the fine characters of large fruit strains.

▲Fig1. One to three kg of large fruit has good thickness of pulp, hard texture, resistant
​​​​​​​to storage and transportation, in line with the needs of the world's major cultivation countries.
