以黑龙江早粳稻品种(品系)为材料,采用随机区组试验设计,比较了不同产量类型水稻商品品质(加工品质和外观品质)的差异。结果表明:加工品质呈低产、中低产类型好于中产类型好于高产类型的趋势,外观品质中垩白粒率和垩白度均呈低产类型好于中产类型好于中低产类型好于高产类型的趋势,长宽比呈低产类型好于中低产类型好于高产类型好于中产类型的趋势,低产、中低产类型精米率极显著高于其它类型,低产类型的垩白粒率、垩白度均极显著低于其它类型。整体来看,低产类型水稻的商品品质优于其他产量类型。
Taking the early japonica rice varieties (lines) of Heilongjiang as materials, the random block design was used to compare the differences of the quality (processing quality and appearance quality) of the rice varieties with different yield types. The results showed that the processing quality was low yield, the middle and low yield type was better than the middle type and the high yield type. The chalky grain rate and chalky appearance of the appearance quality showed that the low yield type was better than the middle yield type and the middle low yield type was better than the high yield type , The trend of low-yield type was better than the middle-low yield type, and the middle-low yield type was better than the middle-yielding type.The milled rice rate of low-yielding and middle-low yielding type was significantly higher than that of other types and low yielding types of chalkiness, Both were significantly lower than the other types. Overall, the product quality of low-yielding rice is superior to other yield types.
