镇江地区5个粳稻品种产量因素及穗粒数相关基因差异分析
Difference Analysis of Yield Factors and Spikelet Number-Related Genes of Five Japonica Rice Varieties in the Zhenjiang Region
摘要
Abstract
We investigated the differences in yield and its component factors among five different Japonica rice varieties in the Zhenjiang re-gion and analyzed the impact of spikelet number related gene sequences on yield.Field experiments were conducted on the varieties of Zhendao 11,Ningjing 3,Ningjing 6,Wuyunjing 24,and Wuyunjing 23.Results showed that Wuyunjing 23 exhibited excellent performance in terms of primary branch number and spikelet number per panicle,yielding the highest production.Correlation analysis revealed that plant height was significantly negatively correlated with yield,while primary branch number and spikelet number per panicle were significantly positively corre-lated with yield.Comparative gene analysis indicated that key genes DEP1,Ghd7,Gn1a,OsGA20ox1,and NOG1 exhibited amino acid varia-tions between the tested varieties and high-yield varieties,but there were no sequence differences within the tested varieties.Among the five tested varieties,Wuyunjing 23 in the Zhenjiang region could achieve higher yield benefits.关键词
