- Abstract
[Objective] In order to provide important reference for selection the new fragrant rice varieties with high quality, the contents of various amino acids of genii plasm resources of fragrant rice in the Southern Henan province were detected and the difference of amino acid contents in the fragrant rice was also analyzed. [Method] The fragrant rice flour was treated by the acid hydrolysis method, then the content of amino acids in the 18 fragrant rice varieties of rice gennplasm resources in the South Henan province was determined and analyzed by the automatic amino acid analyzer. [Result] The total amino acid content of different fragrant rice varieties was obviously different among the gennplasm resources of fragrant rice in the South of Henan province. The difference of total amino acid content between Heixiangdao 193 and Xinxianggeng 1 was 23.33 mg·g-1. The total essential amino acid content varied greatly from gennplasm resources of fragrant rice in South Henan, and the range of its variation was between 25.13 and 34.13 mg·g-1. The content of limiting amino acid and aromatic amino acid content of 18 fragrant rice varieties varied greatly, and the highest content of lysine was the Aiganxiangdaowan. Meanwhile, the content of heterocyclic amino acids was also abundant in the Aiganxiangdaowan. [Conclusion] Through the detection and analysis of amino acid content in the fragrant rice varieties of rice germplasm resources in the South Henan province, it was found that there were obvious differences in the content of amino acids in the 18 varieties of fragrant rice, which will provide important germplasm resources of fragrant rice for breeding new varieties with high nutritional quality in the future.
