Introduction performance of japonica soft rice variety Zhehexiang 2 in Zhejiang Province
Zhehexiang 2 is a single season conventional late japonica rice variety developed in collaboration with Jiaxing Academy of Agricultural Sciences,Zhejiang Dahe Seed Industry Co.,Ltd.,and Zhejiang Wuwangnong Seed Shareholding Co.,Ltd.In 2021,initially the experiment was conducted in Zhejiang Province and simultaneously the molecular characteristics analysis was conducted using molecular markers.The results showed that the average yield of Zhehexiang 2 was 9 664.5 kg·hm-2,which increased by 5.8%compared with the control Xiushui 134.And its growth period was 160 days,which was 3.0 days more than the control variety.Moreover,this variety carries rice blast resistance genes,including Pi36,Pi50,Pizt,Pi63,Pib,Pi64,Pish,Pi37,Ptr,Pikm2 and Pi35.The sequence analysis revealed that there was a 7 bp missing at the 7th exon of the rice aroma regulating gene.Compared with the soft rice variety Nanjing 46,there is a G/T mutation in the first base of the Wx gene in Zhehexiang 2.These results will provide a theoretical foundation for the promotion and application of this variety and further genetic improvement.
