对黑龙江省审定通过的22个香稻品种的产量和品质性状进行了分析。结果表明,适当增加每穗粒数有利于提高香稻品种产量,千粒重对产量的影响较小;没有香稻品种品质达到国标一级,应降低垩白粒率、垩白度和增加胶稠度长度来提高食味口感。这些香稻品种主要是以五优稻1号、绥粳4号为亲本育成的品种,五优稻1号衍生品种占36.0%,绥粳4号衍生品种占59.0%,说明黑龙江省香稻遗传基因狭窄,应拓宽香稻种质资源,丰富遗传基础。

The yields and quality traits of 22 aromatic rice varieties in Heilongjiang Province were analyzed in this paper. The results showed that increase the grains per spike appropriately is conducive to improve the yield. The 1 000-grain weight has less effect on grain yield. There is no variety come up to the first national standard on the quality traits. We should decrease the chalky grain rate and chalkiness degree, and increase the length of gel consistency to improve rice taste. These aromatic rice were mainly bred by Wuy-oudao 1 and Suijing 4, the varieties which derived from Wuyoudao 1 are accounted for 36.0%and the varieties derived from Suijing 4 are accounted for 59.0%. The genetic basis of aromatic rice is stenosis, we should widen the germplasm resources of aromatic rice and enrich genetic bases.
