Resistance and Susceptibility to Insect Pests in Glossy Genetic Lines of Brassica oleracea in Connecticut, USA
The glossy cauliflower PI 234599 has been used in breeding programs as a source of resistance to diamondback moth, Plutella xylostella (L.), and other lepidopterous larvae, but the relationship between insect resistance and glossiness has not been clear. One way to clarify this relationship is to find glossy lines carrying different genes for glossiness and test their resistance to insects. In ...
متن کاملGenetic engineering of rice for resistance to homopteran insect pests
The rice brown planthopper (BPH; Nilaparvata lugens) is a serious pest of rice crops throughout Asia, damaging plants both through its feeding behavior and by acting as a virus vector. Like many homopteran pests of crops, it is primarily a phloem feeder, abstracting sap via specially adapted mouthparts. An artificial diet bioassay system for this pest was developed to allow the effects of poten...
متن کاملIntrogression of the Aegilops speltoides Su1-Ph1 Suppressor into Wheat
Meiotic pairing between homoeologous chromosomes in polyploid wheat is inhibited by the Ph1 locus on the long arm of chromosome 5 in the B genome. Aegilops speltoides (genomes SS), the closest relative of the progenitor of the wheat B genome, is polymorphic for genetic suppression of Ph1. Using this polymorphism, two major suppressor loci, Su1-Ph1 and Su2-Ph1, have been mapped in Ae. speltoides...
متن کاملGenetic compensation abilities of Aegilops speltoides chromosomes for homoeologous B-genome chromosomes of polyploid wheat in disomic S(B) chromosome substitution lines.
The S genome of Aegilops speltoides is closely related to the B and G genomes of polyploid wheats. However, little work has been reported on the genetic relationships between the S-genome and B-genome chromosomes of polyploid wheat. Here, we report the isolation of a set of disomic substitutions (DS) of S-genome chromosomes for the B-genome chromosomes and their effects on gametophytic and spor...
متن کاملIntrogression of Aegilops speltoides segments in Triticum aestivum and the effect of the gametocidal genes
Background and Aims Bread wheat (Triticum aestivum) has been through a severe genetic bottleneck as a result of its evolution and domestication. It is therefore essential that new sources of genetic variation are generated and utilized. This study aimed to generate genome-wide introgressed segments from Aegilops speltoides. Introgressions generated from this research will be made available for ...
