QTL Mapping by SLAF-seq and Expression Analysis of Candidate Genes for Aphid Resistance in Cucumber
Cucumber, a very important vegetable crop worldwide, is easily damaged by pests. Aphid is one of the most serious cucumber pests and frequently cause severe damage to commercially produced crops. Understanding the genetic mechanisms underlying pest resistance is important for aphid-resistant cucumber varieties breeding. In this study, two parental cucumber lines, JY30 (aphid susceptible) and EP...
متن کاملQTL analysis for diamondback moth resistance in canola (Brassica napus L.)
Diamondback moth (DBM), Plutella xylostella L. is the most injurious defoliage insect pest of canola in Ardabil province of Iran. It occurs annually and causes damage in canola fields. This study was performed to identify QTLs controlling resistance to diamondback moth using SSR and RAPD markers. An F2:4 population of 180 families derived from crossing between cv. ‘SLMO46’ and cv. ‘Quantum’ wer...
متن کاملQuantitative Trait Loci (QTL) Analysis Reveals Both Broad-Spectrum and Isolate-Specific QTL for Scab Resistance in an Apple Progeny Challenged with Eight Isolates of Venturia inaequalis.
ABSTRACT The major scab resistance gene Vf, extensively used in apple breeding programs, was recently overcome by the new races 6 and 7 of the fungal pathogen Venturia inaequalis. New, more durable, scab resistance genes are needed in apple breeding programs. F(1) progeny derived from the cross between partially resistant apple cv. Discovery and apple hybrid 'TN10-8' were inoculated in the gree...
متن کاملIdentification of causal relationships among traits related to drought resistance in Stylosanthes scabra using QTL analysis.
Previous studies have shown that a negative relationship exists between transpiration efficiency (TE) and carbon isotope discrimination (Delta) and between TE and specific leaf area (SLA) in Stylosanthes scabra. A glasshouse experiment was conducted to confirm these relationships in an F(2) population and to study the causal nature of these relationships through quantitative trait loci (QTL) an...
متن کاملSusceptibilities of apple aphid and spirea aphid collected from apple in the Pacific Northwest to selected insecticides.
Laboratory bioassays using leaf disks of apple dipped in test solutions of insecticides demonstrated that the apple aphid, Aphis pomi De Geer, and the spirea aphid, Aphis spiraecola Patch, differed significantly in susceptibility to a number of insecticides registered for control of aphids on apple (Malus spp.). Compared with A. pomi, A. spiraecola was approximately four- and three-fold less su...
