Breeding and Nutrient Content Analysis of Glutinous Rice Mutant Yuanpeinuo With High Remained Germ
摘要
Abstract
To innovate glutinous rice varieties with rich nutrition components,the seeds of Ningjing 3 were irradiated by 250 Gy 60Co-γ rays,and combining tissues cultivation,a glutinous rice mutant Yuanpeinuo,with high yield,good quality and disease resistance,was successfully obtained.The rate of Yuanpeinuo kernels remained germ was over 80％.The germ-remaining rice of Yuanpeinuo,brown and polished rice of Ningjing 3 were used to detect nutrient compositions including protein,micronutrient elements,amino acids,etc.Meanwhile,composition contents among the three samples were also analyzed and compared.The results showed that protein content of the Yuanpeinuo with remained germ was 8.25％,content of K,Ca,Mg,Na,Gu,Zn,Fe was 898.41,107.55,95.13,21.39,1.11,12.12,and 10.51 mg·kg-1,respectively,the total content of 17 types amino acids was 117.2 g·kg-1,and the content of essential amino acids was 39.6 g· kg-1.The nutritional value of Yuanpeinuo with remained germ was similar to that of brown rice of Ningjing 3,and significantly higher than that of polished rice of Ningjing 3.This work provides a scientific basis for further use and development of Yuanpeinuo.关键词
