高直链淀粉含量水稻新品种筛选与分析

    Analysis and Screening of New Rice Varieties with High Amylose Content

    • 摘要: 为筛选出适宜米粉加工的专用稻新品种,以满足日益增长的米粉加工业对专用稻米的需求。2024年选用澜优151、澜优7954、洆优7954等11个高直链淀粉含量的水稻新品种,以宜优673为对照(CK),在福建省农业科学院南平现代农业育种基地开展品种筛选试验,对参试品种的生育期、主要农艺性状、产量、稻瘟病抗性和稻米品质等方面进行系统比较分析。结果表明:澜优7954和洆优7954这2个品种产量高,分别比宜优673(CK)显著增产7.23%和6.38%,中抗和抗稻瘟病,稻米直链淀粉含量高(分别为26.7%和26.3%),综合性状表现突出,是理想的米粉加工专用稻品种。澜优151、璇两优外七和洆优3219等3个品种产量较高,分别比宜优673(CK)增产4.26%、2.13%和0.43%,稻瘟病抗性强,稻米直链淀粉含量高(分别为27.2%、26.0%和26.2%),综合性状表现较好,可以作为米粉加工专用稻的重要候选品种。

       

      Abstract: To screen out new rice varieties suitable for rice noodle processing and satisfy the increasing demand of the rice noodle processing industry for specialized rice, 11 new rice varieties with high amylose content, including Lanyou 151, Lanyou 7954, and Chengyou 7954, were selected in 2024. Using Yiyou 673 as the control variety(CK), a variety screening test was conducted at the Nanping Modern Agricultural Breeding Base of Fujian Academy of Agricultural Sciences. Systematic comparative analysis was conducted on growth period, main agronomic traits, yield, rice blast resistance, and rice quality of the tested varieties. The results showed that Lanyou 7954 and Chengyou 7954 had high yields, significantly increased by 7.23% and 6.38% compared to Yiyou 673(CK), respectively. They showed moderate to high resistance to rice blast, and high amylose content(26.7% and 26.3%, respectively), exhibited exceptional comprehensive traits and was ideal rice varieties specifically developed for rice noodles processing. Lanyou 151, Xuanliangyou Waiqi, and Chengyou 3219 had higher yields, increasing by 4.26%, 2.13%, and 0.43% compared to Yiyou 673(CK), respectively. They showed strong resistance to rice blast and high amylose content(27.2%, 26.0%, and 26.2%, respectively), with good comprehensive traits, could be important candidate varieties for special rice used in rice noodles processing.
