Tomato (L. esculentum Mill.) Genotypes variability of fruit traits

Abstract

Tomato (Lycopersicum esculentum Mill.) is vegetable which could be produced and consumed in a many different ways, due to its variability, made by breeding programs. Variability of analyzed genotypes was determinated for further fruit traits: average mass, fruit shape, locules number and dry matter content. Variability source structure was determinated using principal components analysis (PCA). Three main components, which explain 94,2 % of total variability, were chosen for further analysis. The biggest part of the first main component has fruit shape and locule number. The second component is determinated by dry matter content, and the third by the fruit mass. For more precisely perception of homology and divergence between analyzed genotypes, nonhierarchical grouping analysis (k-means) was performed, and genotypes were divided into three groups. Divergency was determinated for fruit mass and locule number, while for index shape and dry matter contetent analyzed genotypes are homologous. The aim of this study is to examine tomato genotypes variability for fruit traits

Reaction of different tomato cultivars toward race 1 of Fusarium oxysporum f. sp. lycopersici

“…Most sensitive to fusarium wilt were S-35 x L-4 INTRODUCTION Tomato (Lycopersicum esculentum Mill.) is one of the most important vegetable crops worldwide that could be used in many different ways, fresh as well as processed (GLOGOVAC et al, 2010;RADZEVIČIUS et al, 2009). Due to expansion of tomato production large number of different tomato varieties is being grown in Serbia, which caused apperence of different disease pathogens that threaten this production (MILIJAŠEVIĆ et al, 2009).…”

Genetic analysis for growth and yield character association in different genotypes of tomato (Solanum lycopersicum L.)

“…In India, tomato occupies an area of 7.7 million hectare with a production of 193.97 million ton and productivity of tonnes per hectare (FAO, 2012) [5] . It is a rich source of vitamins, minerals and organic acids those imparts considerable amounts of antioxidant property in human body (Tomlekova et al, 2007;Glogovac et al, 2010) [6,7] that alleviate chronic diseases such as cancer and coronary heart disease (Canene-Adams et al, 2005; Omoni and Aluko, 2005; Kun et al, 2006) [8,14,9] . Being a self-pollinated crop, it has a tremendous potential for heterosis breeding and it is used in different breeding programme for genetic studies.…”

Genetic variability, character associations and path coefficient studies in tomato (Solanum lycopersicum L.) grown under terai region of West Bengal

“…In India, tomato occupies an area of 0.87 million hectare with a production of 17.50 million ton and productivity of 20.11 tons per hectare (FAO, 2012) [4] . It is a rich source of vitamins, minerals and organic acids those imparts considerable amounts of antioxidant property in human body (Tomlekova et al, 2007;Glogovac et al, 2010) [5,6] that alleviate chronic diseases such as cancer and coronary heart disease (Canene-Adams et al, 2005; Omoni and Aluko, 2005; Kun et al, 2006) [7,8,9] . Being a self pollinated crop, it has a tremendous potential for heterosis breeding and it is used in different breeding programme for genetic studies.…”
