Available in PDF, EPUB and Kindle. Book excerpt: First published 15 years ago, Compendium of Pea Diseases and Pests, Second Edition covers new and updated information for the diagnosis and control of pea diseases. Contributions from worldwide authorities in pea disease research make this new edition the most comprehensive and authoritative guide to pea diseases available. Included in this edition is new and extensive coverage on herbicide and insect feeding injury, fertilizer deficiencies and toxicities, seed vigor, and seed health, as well as updated information on pea-pathogenic virus and bacterial genomes, and sources of resistance to virus diseases. Practical and easy-to-use, the 107 color photographs and the Guide to the Identification of Pea Diseases in the Field will help anyone who works with peas. The updated information provided in this reference will aid in the management of pea diseases worldwide and help ensure the health of this important crop.

This book was released on 2021 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the several biotic stress factors, viral diseases are a major constraint to sustainable cultivation of country bean (Lablab purpureus [L.] Sweet, family Fabaceae) in subsistence agriculture in Bangladesh. This study was undertaken to characterize Bean common mosaic necrosis virus (BCMNV) and Dolichos yellow mosaic virus (DoYMV) in country bean samples collected from farmers' fields. Total nucleic acid preparations from symptomatic leaves were subjected to high-throughput Illumina sequencing followed by Sanger sequencing of viral amplicons to generate near full-length genome sequences of BCMNV and complete sequence of DNA-A and DNA-B components of DoYMV. In pairwise comparisons and phylogenetic analysis of polyprotein sequences, BCMNV isolates from Bangladesh were found to be distinct strains compared to virus isolates from other countries. Grow-out tests showed seed-to-seedling transmission of BCMNV, implying seed-borne nature of the virus in country beans. An analysis of green pods indicated detrimental effects of virus infection on nutritional quality of pods. Phylogenetic analysis and pairwise sequence comparisons of DoYMV sequences from Bangladesh showed close relationship with corresponding viral sequences from India. Some of the DoYMV isolates from Bangladesh were found to be putative recombinants. Studies were conducted to identify sources of resistance to the pea aphid (PA, Acyrthosiphon pisum) using a world-wide collection of 301 pea genotypes available at the USDA facility in Pullman, WA. A cluster analysis associated with the mean number of adults, nymphs and total aphids that developed on pea lines 10 days after releasing a single adult aphid per plant identified six clusters associated with aphid resistance. Genotyping by sequencing based on single-nucleotide polymorphisms (SNPs) were used in genome-wide association mapping to locate genes or quantitative trait loci linked to PA resistance in which three, nine and six SNPs were associated with resistance to adult, nymph and total number of PA that developed on pea lines, respectively. Seventeen candidate genes were identified in response to PA resistance in pea. The sources of resistance can effectively be used in pea breeding programs to develop cultivars with improved resistance against the pea aphid, a major pest and a vector of viruses damaging peas.
