Traits Analysis of Rice Varieties Approved by Jiangxi Provincial Crop Variety Appraisal Committee in Recent Years

[Objective] The aim was to analyze the yield,quality and disease resistance of 140 rice varieties approved by Jiangxi Province in2009- 2013. [Method] The rice varieties( not including approved sterile lines) approved by Jiangxi Provincial Crop Variety Appraisal Committee in 2009- 2013 were analyzed comprehensively and used to conduct the vertical analysis according to years,moreover,all rice varieties were respectively divided into early rice,one-season rice and late rice,conventional varieties and hybrid varieties,and the hybrid varieties divided into two-line and three-line,to analyze. [Result] The approved rice varieties were mainly three- line hybrid rice,the yield of the twoline hybrid rice varieties was a little higher than that of the three-line hybrid rice varieties,while its premium rate was lower than that of the three-line hybrid rice varieties. The yield of the approved rice varieties was increased 3. 0% than that of control,about 52. 1% of them met the third class of national rice quality standards,almost of them were highly susceptible to rice blast. [Conclusion]The study provides a reference basis for breeding,promotion and application of Jiangxi provincial rice varieties.
