Bacterial plant pathogens of the Pectobacterium genus are responsible for a wide spectrum of diseases in plants, including important crops such as potato, tomato, lettuce, and banana. Investigation of the genetic diversity underlying virulence and host specificity can be performed at genome level by using a comprehensive comparative approach called pangenomics.

MicroRNAs (miRNAs) are short non-coding RNAs that can influence gene expression via diverse mechanisms. Tomato is a fruit widely consumed for its flavor, culinary attributes, and high nutritional quality. Tomato fruit are climacteric and fleshy, and their ripening is regulated by endogenous and exogenous signals operating through a coordinated genetic network.

In the present study, 22 tomato (Solanum lycopersicum L.) genotypes were evaluated to study the extent of genetic diversity through 20 quantitative traits. The genotypes were categorized into 5 distinct clusters using D2 statistics. Cluster I had the maximum number of genotypes (8), followed by clusters IV and V (4 genotypes each) and clusters II and III (3 genotypes each).

There exists a lot of controversy regarding the prevalence of strains in the various parts of the world. In India, however, scant information is available about the prevalence of biovars/races and strains in various parts of the country. Understanding local pathogen genetic diversity is the first step in a successful breeding and integrated disease management programme. One of the purposes of the present investigation on six isolates of R.

The nature and magnitude of genetic divergence was estimated in 35 genotypes of tomato using Mahalanobis D2 – statistics. The genetic material revealed considerable amount of diversity for all the characters investigated. All the genotypes were grouped into 4 clusters. Maximum number of genotypes was accommodated in cluster III.

A set of 24 cross combinations were developed through Line × Tester mating system involving 11 diverse genotypes of tomato and observations were taken for yield and yield attributing characters to study the extent of heterosis in the crosses. Tomato is an autogamous crop and has originated in the Peru region of South America. The experiment was conducted in Randomized Complete Block Design (RCBD) with three replications.

Quantitative trait locus (QTL) mapping is a highly effective approach for studying genetically complex forms of plant disease resistance. With QTL mapping, the roles of specific resistance loci can be described, race-specificity of partial resistance genes can be assessed and interactions between resistance genes, plant development and the environment can be analysed (Young, 1996). DNA markers tightly linked to quantitative resistance loci (QRLs) controlling QDR can be used for marker-assisted selection (MAS) to incorporate these valuable traits.

Genetic diversity study involving twenty one thermo tolerant tomato genotypes was carried out for twelve physiological and biochemical characters at Indian Agricultural Research Institute, New Delhi during summer season of the year 2014. All the genotypes were grouped into 4 distinct clusters using D2 statistics. Cluster I and cluster II comprised of 10 genotypes represented by heat tolerant genotypes while cluster III showed 4 heat sensitive genotypes. The clustering analysis of all genotypes showed that heat sensitive and heat tolerant genotypes were represented by distinct clusters.

As the information, on the nature and magnitude of variability for yield and other characters present in germplasm pool owing to genetic and non-genetic causes, is an important basic pre-requisite for starting any systematic breeding programme to identify superior lines or varieties. Thus, this investigation was undertaken involving 200 genotypes of tomato (Solanum lycopersicum L.) with following objective as genetic divergence studies in tomato. Genetic diversity among 200 tomato genotypes was worked out using D2 statistics.

The present experiment was carried out to investigate yield and quality traits in tomato, in order to generate information regarding the extent of genetic variability, heritability and genetic advance at Regional Research Station, Uchani, Karnal, CCS Haryana Agricultural University, Hisar, Haryana during autumn seasons of 2016 and 2017 involving 43 genotypes. The analysis of variance indicated significantly higher difference among the treatments for all the traits studied indicating presence of substantial amount of genetic variability among the materials studied.

Domestication and selection of crops have notably reshaped fruit morphology. With its large phenotypic diversity, tomato (Solanum lycopersicum) illustrates this evolutive trend. Genes involved in flower meristem development are known to regulate also fruit morphology.

Phosphorus (P) deficiency is one of the major nutrient stresses limiting plant growth. The uptake of P by plants is well considered to be mediated by a number of high-affinity phosphate (Pi) transporters belonging to the Pht1 family.

Molecular diversity analysis on 8 hybrids of tomato generated 27 polymorphic markers. The major allele frequency for the marker SSR1- 23.2 and SSR5-13.1 was least. The polymorphic information content value (PIC) ranged from 0.00 (SSR1-23.2) to 0.86 (SSR1-62.2) with an average PIC value of 0.46 per marker indicating more diversity at DNA level. Alleles ranged from 1-8 per locus with an average of 3.33 alleles per locus. Cluster analysis resulted into 3 main clusters and 4 subclusters. The diverse genotypes can be used for hybridization programmes.

microsatellite markers Tomato (Solanum lycopersicum L.) is one of the most important economically plants in the family Solanaceae. Information about genetic diversity of any crop is important for successful employment of breeding programme and is of great significance to attain sustainability in crop production. The objective of this study was to evaluate the genetic diversity of 24 genotypes of tomato collected from ICAR-IIVR, Varanasi, India, using 25 simple-sequence repeats (SSRs). A total of 64 alleles were detected at an average of 2.720 alleles per SSR locus.
