Summary of field trial conditions at Balm, FL, and Bs2 impact factor.

aNormal: within 5% of typical averages (Table S7).
bRainfall relative to typical monthly totals (Table S7).
cRelative disease pressure based on disease ratings in Table S5(A). High: VF 36 ratings above 7, commercial lines above 5; Low: VF 36 ratings below 6, commercial lines below 5.
dRelative yield summary based on marketable yields in Table S5(B). Low: 1–2 lbs/plant; Medium: 2.5–3.5 lbs/plant; High :4.5–6 lbs/plant. Fall 2008 estimates were approximated by doubling yield from single harvest.
eBs2 impact was calculated by dividing the larger of the two values for marketable yield for VF36-Bs2 homo- or hemizygous plants with the marketable yield for VF 36 plants (Table S5(B)).
