Genetic analysis and trait association in F2 interspecific population in tomato (Solanum lycopersicum L.) using third and fourth degree statistics

The present investigation was assessed using 235 different F2 individuals, their parents and F1 for characters like plant height, moisture, phenol and chlorophyll. These characters are most important for identification of disease effect and characterization for resistance in plants or genotype. Here, in the present study F2 population was developed from the cross between AT-3 (Solanum lycopersicum L) and IIHR-2101 (Solanum habrochaites L.). Then characters which are mentioned above were studied. Regarding the population distribution analysis, only chlorophyll was showed normal distribution in this population while other characters did not show normal distribution in the population. In this cross combination, phenol content was governed by complementary gene action with presence of minor genes, while moisture and plant height were governed by duplicate gene action with dominant property. Above characters interaction was determined through skewness and Kurtosis analysis. | Genetic analysis and trait association in F2 interspecific population in tomato Solanum lycopersicum L. using third and fourth degree statistics
