一种能满足稻麦品质育种筛选、粮食收购饲料加工等需快速测定蛋白质含量的新方法——直接蒸馏法,最近由中国科学院成都生物所植物遗传育种室研究成功,经四川省农科院中心实验室和商业部四川粮科所示范应用,均达到满意的效果,并在成都通过鉴定。稻麦种籽蛋白质含量是评价稻麦营养品质的一项重要指标。籽粒蛋白质含量遗传传递力较低,以蛋白质含量为主要选择压,品质育种需从大批量育种材料中筛选高蛋白质含量的单株,工作量较大,如不能及时对本年度育种材料进行筛 A new method for rapid determination of protein content, such as breeding of rice and wheat, breeding and selection of grain, and processing of feed for grain acquisition, is the direct distillation method. Recently, the plant genetic breeding room was successfully researched by Chengdu Institute of Biology, Chinese Academy of Sciences. Laboratory and Ministry of Commerce, Sichuan food science demonstration applications, have reached satisfactory results, and passed the appraisal in Chengdu. Rice and wheat seed protein content is to evaluate the nutritional quality of rice and wheat is an important indicator. Grain protein content of the lower genetic transmission force, the protein content as the main selection pressure, quality breeding from high-volume breeding materials screening of high-protein content of the individual, the workload is large, such as the current breeding material can not be sieved
