Factor analysis and comprehensive evaluation of the fruit quality of bottle gourd(Lagenaria siceraria)
The objective of this study was to establish a comprehensive evaluation system for assessing fruit quality in bottle gourd for the purposes of quality evaluation,selection,and breeding.Data on 28 fruit quality related traits were collected from 206 bottle gourd germplasm collections.Correlation analysis,factor analysis,cluster analysis,and two-dimensional ordination mapping were conducted to develop a comprehensive evaluation formula for fruit qual-ity in bottle gourd.The results indicated that the variations in the 28 fruit quality traits were different,ranging from 2.71%to 63.60%.The greatest difference was found in the free glutamate(Glu)content,while the least difference was observed in water content.The correlations among all bottle gourd quality indexes differed depending on the col-lection.Nine common factors were extracted from bottle gourd quality indexes with an 86.78%cumulative variance contribution rate through factor analysis.The first common factor explained the indices mainly concentrated in free a-mino acids,with a 38.46%cumulative variance contribution rate.Based on the results of comprehensive analysis and cluster analysis,flesh thickness,soluble solids content,hardness,Glu content,and protein content were select-ed as typical indices for evaluating the fruit quality of 206 bottle gourd germplasm collections.These findings provide valuable resources and a foundation for breeding high-quality bottle gourd.
