26个辣椒品种主要农艺性状分析与测评

Analysis and Evaluation of Main Agronomic Traits of 26 Pepper Varieties

为了筛选出适于常德春露地栽培的辣椒品种,对26个辣椒品种的13个性状作了相关性分析和聚类分析,并进行群众测评。结果表明:单果重与商品果横径、果肩形状呈极显著正相关,与叶形、果形、熟性呈极显著负相关;单产与单果重呈极显著正相关,与商品果横径、果肩形状呈显著正相关,与果形、熟性、叶形呈极显著负相关;熟性与叶形呈极显著正相关,与果形呈显著正相关,与商品果横径、单果重、果肩形状呈极显著负相关;将26个品种聚类分成4大类,果形和产量是影响聚类结果的重要因素。农民测评投票的选择意向与株高、株幅、果肩形状、病毒病抗性呈极显著相关关系,相关系数分别为0.538、0.542、0.570、0.518,与果实横径、叶形、果形呈显著相关;评选出‘湘研青翠’、‘丰抗21’、‘更新8号’、‘兴蔬201’等品种适于当地栽培。

To screen out pepper varieties suitable for spring open cultivation in Changde,we analyzed 13 characters by correlation analysis,cluster analysis and mass evaluation for 26 pepper varieties.The single fruit weight was significantly correlated with the transverse diameter of commodity fruit and the shape of fruit-shoulder.The single fruit weight was significantly negatively correlated with the leaf shape,fruit shape and maturity.The yield per plant was significantly correlated with the single fruit weight,and significantly positively correlated with the transverse diameter of commodity fruit and the shape of fruit-shoulder,but was significantly negatively correlated with the leaf shape,fruit shape and maturity.The maturity was significantly correlated with the leaf shape,and significantly positively correlated with the fruit shape,but was significantly negatively correlated with the transverse diameter of commodity fruit,the single fruit weight and the shape of fruit-shoulder.The 26 varieties were divided into four categories based on cluster analysis.The fruit shape and yield were the most important factors affecting the clustering results.The willingness of farmers to choose a variety was correlated with plant height,plant width,shape of fruit-shoulder,and virus resistant.And the correlation coefficient was 0.538,0.542,-0.570,-0.518,respectively.It was correlated with transverse diame-ter of fruit,leaf shape and fruit shape.‘Xiangyan-qingcui',‘Fengkang 21',‘Gengxin 8',‘Xingshu 201'were suitable for cultivation in Changde.
