辽宁省审定的水稻品种基本情况分析

Analysis on the Basic Situation of Rice Variety Certified by Liaoning Province

对2019年辽宁省审定的19个水稻品种基本情况进行了分析。辽宁省水稻品种分4个生态类型,品种审定年均数量稳中有升,其中科研、教学单位比企业稍多。育种方法以常规杂交为主。产量与以往相比有较大进步,但距全国近期平均水平仍有差距。产量性状协调发展才是提高产量的有效途径。品质主要性状指标优质达标率94.44%。不同生态类型品种品质有差异,中早、晚熟品种优质等级更高。提高糙米率、降低垩白度,是省内提高优质等级的关键。

The basic situation of 19 rice varieties approved in 2019 in Liaoning province was analyzed.There were four ecological types for rice varieties in Liaoning province,the average annual number of varieties approved has risen steadily,and scientific research,colleges and universities approved a little more varieties than enterprises.The breeding method is mainly based on conventional hybridization.The yield has made great progress,and there was still a gap compared with the recent national average.The coordinated development of yield traits was the effective way to increase yield.The high quality compliance rate of the main rice quality character was 94.44%.The quality of different ecological types was different,and the quality grade of mid-early and late-maturity varieties was higher.Improving brown rice rate and reducing chalkiness was the key to improve quality grade in Liaoning province.
