两系不育系1892S选育的品种特征特性分析OA
Analysis of the characteristics and traits of the variety selected from the two-lined sterile line 1892S
以农业农村部和各省水稻(Oryza sativa L.)区域试验和生产试验数据为基础,对2020年以来通过国家农作物品种审定委员会审定的适宜在长江中下游区域作一季中稻种植的以两系不育系1892S为母本的杂交品种基本性状进行了分析.结果表明,1892S系列组合品种普遍生育期偏中长、株高适宜、穗大粒多、单穗着粒较密、结实率较高,但有效穗数中等,多为穗粒兼顾型或大穗型品种.1892S可以选配出整精米率较高、米质较优良的组合,1892S系列组合品种在病虫害抗性方面还需进一步加强.
Based on the data from rice regional and production trials conducted by the Ministry of Agriculture and Rural Affairs and various provinces,the analysis was conducted on the basic traits of hybrid varieties with the two-line sterile line 1892S as the maternal parent,which has been approved by the National Crop Variety Approval Committee since 2020 and were suitable for one season mid season rice cultivation in the middle and lower reaches of the Yangtze River.The results showed that the 1892S series combination vari-eties generally had a medium to long growth period,suitable plant height,large panicles and more grains,dense grain setting per pani-cle,and high seed setting rate.However,the effective number of panicles was moderate,and most of them were varieties with both panicle and grain balance or large panicle types.Furthermore,1892S could be used to development combinations with higher head rice yield and better rice quality.The pest and disease resistance of the 1892S series combination varieties needs to be further im-proved.
