两系不育系1892S选育的品种特征特性分析
Analysis of the characteristics and traits of the variety selected from the two-lined sterile line 1892S
摘要
Abstract
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.关键词
