目前,在育种机构中评定水稻样品的加工性质,常采用下列的一些指标:干粒重,谷壳率,胚乳透明度,碎米率,谷粒的长、宽、厚度,长度比率,总出米率和整精米率。确定后面的两个指标是很繁重的一项工作,因为子粒的去壳和碾磨,必须要有高档的专门技术装置才能进行(Пур和Sata-ke型装置)。因此,地方性科研所和育种站,因实验技术设备的缺乏,对原始材料和新品种的这些极重要性状指标的评定工作难以进行。但在有这种设备的科研机构中,对少量原始材料样品或杂交品系以及有种早期的选株,要进行多项指标的评定。评定时要求子粒不少于100克,通常要在繁殖后和育种程序结束时,到达其品比试验阶 Currently, some of the following indicators are commonly used to assess the processing properties of rice samples in breeding institutions: dry weight, chaff, endosperm transparency, broken rice rate, grain length, width, thickness, length ratio, Rate and headmilk rate. The determination of the latter two indicators is a very laborious one as the pellets are dehulled and milled, requiring high-grade specialized equipment to be used (the Пур and Sata-ke devices). Therefore, the local research institutes and breeding stations, due to the lack of experimental technology and equipment, the assessment of these very important traits indicators of the original materials and new varieties is difficult to carry out. However, in scientific research institutes with such equipment, a number of indicators are to be assessed for a small amount of raw material samples or hybrid lines and for an early selection. Grading requirements of not less than 100 grams of seeds, usually after breeding and breeding programs at the end, reach its product testing phase
