Plum Regal F1 is a high productive paste tomato. Sugar content is not that good. It is a cross from the NCSU lines NC 30P x NC 25P.
Plum Regal F1 is homozygous for the old gold crimson ogc gene, which makes the fruit extra deep red and contains more lycopene.
Plant growth habit is determined.
Homozygous resistance for:
Verticillium wilt (Ve gene)
Fusarium wilt (I and I-2 genes)
Heterozygous resistance for
tomato spotted wilt virus (TSWV) (Sw5 gene)
Late blight (ph-3 gene)
Plum regal F1 is segregating for the ms-10 gene for male sterility linked to the green stem seedling marker gene aa.
Heterozygous ph-3 gene against late blight appears to be insufficiently effective. Better is the combination of ph-2 with ph-3 or homozygous ph-3.
Is there an open polinated version of this variety available?
