Resistance to Pear Psylla Nymphal Feeding of Germplasm from Central Europe
Pear psylla (Cacopsylla pyricola Foërster) is the most serious pest of the European pear (Pyrus communis L.) in the production regions of Europe and North America. Nine plant germplasm introductions of pear from Central Europe recently released from plant quarantine were evaluated for nymphal feeding antixenosis, a primary mode of resistance known to be correlated with ovipositional antixenosis...
متن کاملGenetic Diversity of pear (Pyrus spp) Germplasm Assessed by Simple Sequence Repeat (SSR) and Morphological Traits
This study was conducted to identify and recognize relations and diversity among accessions of the Iranianpears (Pyrus spp). A total of 34 pear accessions, derived presumably from at least six species, were subjected to simple sequence repeat (SSR) analysis. The Japanese and the Chinese pear samples were; “Housui” and “Yali” cultivars, example of Pyrus pyrifolia and P. bretschneideri, respectiv...
متن کاملRelative attractiveness of colour traps to pear psylla in relation to seasonal changes in pear phenology
Monitoring of pear psylla (Cacopsylla pyricola (Förster), Hemiptera: Psyllidae) prior to spring bud break could aid in predicting the size of subsequent spring populations and lead to improved proactive management decisions. Yellow traps are commonly used to monitor hemipteran pests including pear psylla, but very little is known regarding seasonal changes in attractiveness of yellow traps or r...
متن کاملIdentification of Pyrus Single Nucleotide Polymorphisms (SNPs) and Evaluation for Genetic Mapping in European Pear and Interspecific Pyrus Hybrids
We have used new generation sequencing (NGS) technologies to identify single nucleotide polymorphism (SNP) markers from three European pear (Pyrus communis L.) cultivars and subsequently developed a subset of 1096 pear SNPs into high throughput markers by combining them with the set of 7692 apple SNPs on the IRSC apple Infinium® II 8K array. We then evaluated this apple and pear Infinium® II 9K...
متن کاملThe Draft Genome Sequence of European Pear (Pyrus communis L. ‘Bartlett’)
We present a draft assembly of the genome of European pear (Pyrus communis) 'Bartlett'. Our assembly was developed employing second generation sequencing technology (Roche 454), from single-end, 2 kb, and 7 kb insert paired-end reads using Newbler (version 2.7). It contains 142,083 scaffolds greater than 499 bases (maximum scaffold length of 1.2 Mb) and covers a total of 577.3 Mb, representing ...
