The invention relates to novel melon plants producing fruits displaying a combination of a long shelf-life trait as well as a maturity indicator trait. The invention also relates to seeds and parts of said plants, for example fruits. The invention further relates to methods of making and using such seeds and plants. The invention also relates to novel genetic sequences associated with a rind-turning phenotype at maturity, which, when combined with a long shelf-life allele, significantly alters the characteristics of the maturing melon fruit, functions as a reliable maturity indicator while retaining suitable marketable features and results in a novel melon plant type.

Melon plants with maturity indicator

The present invention relates to aplant, in particular a squash plant, having wide spectrum resistance to potyvirus such as Zucchini Yellow Mosaic Virus (ZYMV), Watermelon Mosaic Virus (WMV), Papaya Ringspot Virus (PRSV) and Moroccan watermelon mosaic virus (MWMV). Methods of selecting a squash plant having wide spectrum potyvirus resistance by marker assisted breeding are also provided.

Cucurbita plant resistant to potyvirus

The present invention relates to aplant, in particular a squash plant, having wide spectrum resistance to potyvirus such as Zucchini Yellow Mosaic Virus (ZYMV), Watermelon Mosaic Virus (WMV),Ringspot Virus (PRSV) and Moroccan watermelon mosaic virus (MWMV). Methods of selecting a squash plant having wide spectrum potyvirus resistance by marker assisted breeding are also provided.

Methods for conveyingf.sp.(FOM) race 1,2 resistance into non-resistant melon germplasm are provided. In some embodiments, the methods include introgressing FOM race 1,2 resistance into a non-resistant melon using one or more nucleic acid markers for marker-assisted selection among melon lines to be used in a melon breeding program, wherein the markers are linked to FOM race 1,2 resistance. Also provided are quantitative trait loci (QTLs) associated with resistance to FOM race 1,2; isolated and purified genetic markers associated with FOM race 1,2 resistance; melon plants, seeds, and tissue cultures produced by any of the disclosed methods; fruit and seed produced by the disclosed melon plants; and compositions including amplification primer pairs capable of initiating DNA polymerization by a DNA polymerase on melon nucleic acid templates to generate melon marker amplicons.
