摘要 【目的】分析新疆不同香型水稻品种产量和品质性状,筛选出适合新疆稻区种植的优质丰产香型水稻品种。【方法】以11份香型水稻品种为供试材料,测定不同香型水稻品种的产量及其构成因子和品质指标,利用相关性、主成分及聚类分析,综合评价不同香型水稻品种产量及品质性状的差异。【结果】11份香型水稻品种产量和品质性状间存在不同程度差异,变异系数2.70%~69.19%,变异主要体现在穗粒数、垩白度和垩白率上。产量及品质性状间存在较多的相关关系,千粒重与粒长存在显著正相关,产量与垩白率、胶稠度呈显著正相关。综合得分新粳伊20号最高为2.5659,新粳香53号最低为-2.0226,当欧式距离为10时香型水稻品种被分为3类,第I类香型水稻品种占比63.64%,第Ⅱ类香型水稻品种占比27.27%,第Ⅲ类香型水稻品种是新粳伊20号,占比9.09%,第Ⅲ类香型水稻优质丰产性最好,第I类优质丰产性居中,第Ⅱ类最差。新粳伊20号优质丰产性最好。【结论】香型水稻品种新粳伊20号优质丰产性最好,提高穗粒数、降低垩白率可以作为新疆香型水稻产量和品质改良的关键。 【Objective】This research aims to screen out high-quality and high-yield aromatic rice varieties,which are suitable for rice planting in Xinjiang region.【Methods】The yield,component factors and quality indexes of the 11 aromatic rice varieties were measured,and the differences of yield and quality traits of different aromatic rice varieties were comprehensively evaluated by correlation,principal component analysis and cluster analysis.【Results】There were differences in yield and quality traits among the 11 aromatic rice varieties,with the variation coefficients ranging from 2.70%to 69.19%,and the variation was mainly reflected in kernels per panicle,chalky degree and chalky rate.The 1,000-grain weight was positively correlated with grain growth,and the yield was positively correlated with chalky rate and gel consistency.Principal component analysis showed that Xinjingyi 20 had the highest comprehensive score of 2.565,9,and Xinjingxiang 53 had the lowest comprehensive score of-2.022,6.Cluster analysis showed that when the European-style distance was 10,aromatic rice varieties were divided into three classes,aromatic rice varieties accounted for 63.64%in the class I;aromatic rice varieties accounted for 27.27%in the class II;in the class III,the aromatic rice variety was Xinjingyi 20,which accounted for 9.09%.The quality and yield of aromatic rice varieties in the class III were the best,which was the worst in the class II.Comprehensive analysis showed that Xinjingyi 20 had the best quality and high yield.【Conclusion】Xinjingyi 20 has the best quality and high yield.In addition,increasing kernels per panicle and reducing chalky rate might be the key research direction for improving yield and quality of aromatic rice varieties in Xinjiang.
