Morphoagronomic Characterization of Tomato Plants and Fruit: A Multivariate Approach

Abstract EN

Consumers in the fresh fruit market choose fruits mainly following criteria related to the external appearance.

However, the introduction of new material for planting depends on the productive capacity of the plant as well as on the formation of fruit that meets consumer desires.

Given the above, the objective of this study was to morphoagronomically characterize tomato genotypes using multivariate statistics.

The genotype seedlings (Ellus, Black Mauri, Green Zebra, Green Tomato, Pomodoro Marmande, Pomodoro Fiorentino, Pitanga, and Black Krim) were transplanted 30 days after sowing.

The morphoagronomic characterization of the genotypes was carried out by evaluating plants and fruits.

The data were analyzed using descriptive analysis, namely, position and variability measurements.

In addition, a multivariate cluster analysis and a principal component analysis were carried out for plant and fruit attributes.

The cluster and principal component analyses were efficient in characterizing plants and/or fruits of different tomato genotypes.

Such efficiency enhances result interpretation and proposed inferences, with applied relevance for the producers.

The genotype Ellus has a combination of morphoagronomic plant and fruit traits superior to other genotypes.

Such superior traits enable a high productivity.
