Inheritance of resistance to papaya ringspot virus-watermelon strain (PRSV-W) in 'Whitaker' summer squash line

Abstract

-The objective of this work was to study the genetic control of the PRSV-W (Papaya

A combined BSA-Seq and linkage mapping approach identifies genomic regions associated with Phytophthora root and crown rot resistance in squash

“…For plotting QTL effects and estimating QTL allele frequencies in the two F2 cohorts, missing GBS genotypes were imputed using the Viterbi algorithm as implemented in the argmax.geno function. Significant differences between rAUDPC means for F2:3 families with differing QTL marker alleles were determined using Tukey's honestly significant difference test at a=.05 using the function HSD.test in the R package agricolae (Mendiburu and Simon 2015). annotate variants between Pc-NY21 and Dunja for their putative functional impact on these genes.…”

Natural Resistances to Viruses in Cucurbits

“…Other studies have suggested that resistance is quantitatively inherited, with several genes with major effects, along with genes with minor effects [184]. The resistance to PRSV seems to be digenic [166,168] or controlled by a major gene with several genes with minor effect [167]. More recently, resistance to MWMV has been reported in C. ecuadorensis, controlled by two recessive genes, none of them related to eIF4E translation factor [171].…”

“…Resistance to PRSV has been found in Zapatillo redondo, from Uruguay [164]. In some C. maxima sources, the resistance to PRSV seems to be controlled by two or three partially dominant or recessive genes [166,167].…”
