Abstract
Nowadays, although there are several studies based on peach phenotypic diversity and adaptability,there is no current research regarding associations among characters using multivariate statistical meth-ods which provide more trustable conclusions than bivariate analysis. For this reason, we evaluated notonly the adaptability of the accessions but also the relationships among qualitative and quantitative traitsapplying Multiple Correspondence Analysis and [ver mas...]

dc.description.abstractNowadays, although there are several studies based on peach phenotypic diversity and adaptability,there is no current research regarding associations among characters using multivariate statistical meth-ods which provide more trustable conclusions than bivariate analysis. For this reason, we evaluated notonly the adaptability of the accessions but also the relationships among qualitative and quantitative traitsapplying Multiple Correspondence Analysis and Factor Analysis, respectively. The study was carried outon seventy-seven nectarine and one hundred and thirty-two peach accessions grown in Argentina thatwere characterized with 35 fruit quality, agronomic and phenological traits during 3 seasons. MultipleCorrespondence Analysis revealed that freestone trait would be associated with strong anthocyanin col-oration of the flesh around the brown dark stone while semi-freestone trait would be related to weakor no anthocyanin coloration of the flesh around the light brown stone. Then, Factor Analysis enabledus to identify positive relationships between blooming and sprouting date; harvesting period and yieldand among fruit development period, harvesting date, fruit weight and soluble solid content. In addition,‘phenology traits’, ‘productivity’ and ‘fruit quality and reaping time’ would be unrelated to each other.Furthermore, the agglomerative hierarchical cluster analysis grouped the accessions in accordance totheir similarities and allowed the identification of the most adapted cultivars. We have demonstratedthat this approach is a powerful tool that should be considered for further studies on peach germplasmand it has also the possibility to be applied for other fruit species. Finally, the results of this study pro-vide valuable information for germplasm characterization and for breeding practices aiming to developaccessions adapted to the climatic conditions of the northern of Buenos Aires province.eng
