摘要
为筛选出适宜当地种植的高产优质番茄品种和育种材料,对引进的50份番茄品种的农艺性状进行变异分析、相关性分析、主成分分析和聚类分析。结果表明,50份材料的23个农艺性状的变异系数值在0%~103%之间,变异较为丰富;不同性状之间存在不同程度的相关性,其中单果质量与熟性、叶片长、叶片宽、首节花序、果实横径、果实纵径、单株产量呈极显著正相关,可溶性固形物含量与熟性、首节花序、单果质量、果实横径、果实纵径、单株产量呈极显著负相关;主成分分析将23个农艺性状简化为6个主成分,分别反映了果实发育特性、成熟前果色和授粉受精特性、果实品质特性、果形特性、花序类型特性、果实色泽品质特性,利用主成分分值进行综合评价,筛选出10个优良番茄品种,并通过二维分布图分析了10个优良番茄品种的性状特异性;聚类分析将50份材料分为6个组群,其中第Ⅰ组群的番茄品种在产量和品质方面均表现优良,且综合评价筛选出的10个优良品种中有9个品种属于第Ⅰ组群,说明综合评价与客观事实基本吻合。
To select tomato varieties and breeding material suitable for local cultivation and with high yield and superior quality,this paper conducted variation analysis,correlation analysis,principal component analysis and cluster analysis on agronomic characters of 50 tomato varieties.The results showed that the coefficients of variation of 23 agronomic traits in 50 of tomato materials ranged from 0%-103%,exhibiting relatively rich variation.Correlation with different degrees was existed between different traits.The single fruit weight was very significantly positively correlated with maturity,leaf length,leaf width,first node inflorescence,fruit transverse diameter,fruit longitudinal diameter,and yield per plant.There was significantly negative relationship between soluble solid content with maturity,first node inflorescence,single fruit quality,fruit transverse diameter,fruit longitudinal diameter,and yield per plant.The principal component analysis simplified the 23 agronomic traits into 6 principal components,respectively reflecting fruit development characteristics,fruit color before ripening,pollination and fertilization characteristics,fruit quality characters,fruit shape characters,inflorescence type characteristics and fruit color and quality characteristics.Furthermore,comprehensive evaluation was carried out using principal component score,and 10 excellent tomato varieties were screened out.Character specialties of these 10 excellent tomato varieties were analyzed through two-dimensional distribution map.Cluster analysis divided 50 materials into 6 groups.Among them,tomato varieties in group I performed well in yield and quality.Nine of the 10 varieties screened out through comprehensive evaluation were belonged to group I,indicating the comprehensive evaluation was basically consistent with the objective facts.
