Abstract：In order to screen out the new rice varieties of special rice suitable for rice noodle processing to meet the increasing demand for special rice in the industry of rice flour processing.In 2024,11 new rice varieties with high grain amylose content,including Lanyou 151,Lanyou 7954,and Chengyou 7954,were selected.By taking Yiyou 673 as the control variety(CK),a variety screening experiment was carried out in Nanping Modern Agricultural Breeding Base of Fujian Academy of Agricultural Sciences.Then,the growth period,main agronomic traits,yield,rice blast resistance and rice quality of the tested varieties were systematically compared and analyzed.The results showed that:compared with Yiyou 673(CK),the yield of the two rice varieties,Lanyou 7954 and Chengyou 7954,was significantly increased by 7.23%and 6.38%,respectively.They showed moderate resistance to rice blast and high grain amylose content(26.7%and 26.3%,respectively),exhibiting exceptional comprehensive traits.They were ideal rice varieties specifically developed for the processing of rice noodles.The yield of Lanyou 151,Xuanliangyou Waiqi and Chengyou 3219 was higher than that of Yiyou 673(CK),which increased by 4.26%,2.13%and 0.43%,respectively.They showed strong resistance to rice blast and high grain amylose content(27.2%,26.0%,and 26.2%,respectively),with good comprehensive traits,which could be used as the important candidate varieties for special rice used in the processing of rice noodles.
