Agronomic behavior of four cultivars and 56 F1 tomato populations

Abstract

This research was conducted under a greenhouse at the National Vegetable Seed Production Center located in the municipality of Sipe Sipe, Quillacollo province with the aim of analyzing agronomic behavior in 56 F1 progenies and four hybrid tomato cultivars. The research consisted of 60 genotypes as treatments. Each experimental unit was made up of 6 plants. The variables evaluated were: number of flowers per inflorescence, number of fruits per cluster, weight of fruit, equatorial diameter, polar diameter, heart diameter, thickness of pericarp, number of fruits per plant, weight of fruit per plant, hardness and solids soluble . The data obtained were analyzed with descriptive statistics, correlation, cluster and principal component analysis. Significant correlations were found for the number of fruits per plant and number of flowers per inflorescence with the weight of fruit per plant. The polar dendogram identified four distant groups in the performance and quality components. The principal component analysis identified the degree of association between variables and genotypes, identifying groups correlated to components of fruit yield and quality.
