摘要： 31 Functional components of polished and brown rice and 50 SSR markers fingerprint for boro groups collected from 41 farmers from two village in Xinping county were investigated. The results as follows: We have bred first from rice landrace that Gongmi No. 3 with the highest resistant starch in the world, its resistant starch content of uncooked and cooked of polished rice are 8.0%similar to 8.5% and 10%similar to 13% respectively; meanwhile constructed the DNA fingerprinting of Xinpingzaoxian and Gongmi No.3 with high resistant starch based on 50 SSR markers. The cooked Xinpingzaoxian were steaming again and air-dried,then the resistant starch content were up to 12.2%; At present, Gongmi No.3 is the most ideal rice products to prevent chronic diseases in the World, especially for diabetes. The total amino acids, 4 amino acids and sulfur elements of brown and polished rice for Xinpingzaoxian with high resistant starch, which relatively distribute evenly in scytoblastema and endosperm, but 5 amino acids are unevenly distributed. Iron and zinc content of polished rice is 5.55% and 21.21% of brown rice, respectively.
