摘要: 以19份单季茭白(Zizania latifolia)种质为材料,在夏季高温栽培条件下测定主要农艺性状与品质指标,采用相关性分析、主成分分析、聚类分析及隶属函数法进行综合评价。结果表明,供试茭白种质农艺性状遗传变异丰富,净茭重变异系数最高(47.66%),草酸含量变异系数最低(1.89%);净茭重与壳茭重、净茭长、株高均呈显著正相关,产量相关性状协同性较强,品质性状间存在协同与拮抗关系;主成分分析提取3个特征值大于1的主成分,累计方差贡献率为62.86%,分别代表产量性状、营养器官发育及品质性状。聚类分析结合隶属函数综合评价将种质划分为4个类群,筛选出JS‑3、JS‑2、金茭优株3份综合性状较优的一级种质。

Abstract: Taking 19 single-harvest Zizania latifolia germplasms as experimental materials, 15 agronomic traits and quality indices were determined under summer high-temperature cultivation conditions, and comprehensive evaluation was performed using correlation analysis, principal component analysis (PCA), hierarchical cluster analysis and the subordinate function method. The results showed that the agronomic traits of the tested Zizania latifolia germplasms exhibited abundant genetic variation. The coefficient of variation of trimmed shoot weight was the highest at 47.66%, while that of oxalic acid content was the lowest at 1.89%. Trimmed shoot weight was significantly positively correlated with shoot weight with sheath, trimmed shoot length and plant height. Yield-related traits showed strong synergy, while both synergistic and antagonistic relationships existed among quality traits. Three principal components with eigenvalues greater than 1 were extracted via PCA, with a cumulative variance contribution rate of 62.86%, which represented yield traits, vegetative organ development and quality traits, respectively. The tested germplasms were classified into 4 clusters through hierarchical cluster analysis combined with the comprehensive evaluation based on the subordinate function method, and three first-class elite germplasms, namely JS-3, JS-2 and Jinjiaoyouzhu, were finally screened out.
