New variety of Litopenaeus vannamei

Aquatic improved variety innovative research center

Part : Introduction

There are 5 members in our center, including 3 professions and 1 associate senior. Around the demand for improved varieties in the aquatic industry, combined traditional with modern breeding techniques, we specializes in the breed of new varieties with such characters as high yield, good quality, wide adaptation, multiple resistance, etc. In addition, we provide the technology of production promotion and utilization of new variety. Taking the collection, identification and evaluation of aquatic germplasm resources as research content, the center delves into key genes, reveals the genetic basis of important traits, innovates to identify all kinds of excellent breeding materials and do a scientific test of good traits.

Part : Major achievements or products

1. Team name: Aquatic improved variety innovative research center

2. Achievements:
(1)  “Xinghai-1”, the new variety of Litopenaeus vannamei.
Since 2011, the center has carried out and accomplished multi-character compound breeding program of Litopenaeus vannamei. Currently, Xinghai 1,the new variety of L. vannamei has been approved by the original improved variety committee of the ministry of agriculture. This species has high growth rate and high survival rate. It is suitable for the main cultivation mode of shrimp in the southern coastal. In the process, 30 papers were published, 4 invention patents and 11 utility model patents were obtained.

(2) The new strain of small abalone, Haliotis diversicolor supertexta.
The small abalone H.diversicolor supertexta is the economic important shellfish in the south coast of China. Since 2008, our center, cooperated with Shanwei Honghaiwan aquaculture co., ltd. and Shenzhen Lantingdingzhi aquatic products co., ltd., initiated a selective breeding program to improve the economic traits of small abalone. After six generations of successive selection, the growth rate of the new strain is fast, survival rate is high and the genetic character is stable. By now, we have published 20 related papers, obtained 1 invention patent as well as 6 utility model patents. The achievements "Research and application of the breeding technology of new varieties of Haliotis diversicolor supertexta "has been awarded the second prize of Guangdong agricultural technology promotion award in 2015, and the third prize of science and technology progress of Zhanjiang city in 2014.
