Isolation of Pseudomonas syringae pv. Tomato strains causing bacterial speck disease of tomato and marker-based monitoring for their virulence.

Background: The bacterial speck disease of tomato caused by a bacterial pathogen Pseudomonas syringae pv. tomato is a most important disease causing severe crop losses.

Methods And Results: Present study was conducted to investigate and characterize the population diversity of P.

Genetic analysis of anther culture response and identification of QTLs associated with response traits in wheat (Triticum aestivum L.).

Anther culture is the most effective tool for doubled haploid production of wheat. This investigation was conducted to estimate genetic parameters of anther culture response in wheat and identification of putative Quantitative trait loci (QTLs) associated with response traits. Two varieties of wheat, namely ICR-DH (P) and Sle 1 × 15 (P) and their F and F progenies were used in the present investigation to estimate genetic parameters of anther culture response.

Genetic Diversity Studies and Identification of Molecular and Biochemical Markers Associated with Fusarium Wilt Resistance in Cultivated Faba Bean (.

( L.) is one of the most important legume crops in Egypt. However, production of is affected by several diseases including fungal diseases.

Inheritance of faba bean resistance to Broomrape, genetic diversity and QTL mapping analysis.

Six faba bean parents and their F and F generations were used in this investigation to study the genetic system controlling resistance of faba bean (Vicia faba L.) to broomrape (Orobanche crenata). Most of the F hybrids were tolerant to broomrape.
