Table 2. Summary of field trial conditions at Balm, FL, and Bs2 impact factor.

	Fall 2007	Spring 2008	Fall 2008	Spring 2009	Fall 2010
Temperature a	Normal, hot late	Normal	Normal	Normal	Normal, cool late
Rainfall b	Average, uneven	Low-average	Low	Heavy wks 4–8	Very low
Disease pressure c	High	High	Low	High	Very low
Yield d	Low	Medium	Low-medium	Med-high	Very high
Bs2 impact factor e	11.8	2.8	2.5	2.6	1.5

^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)).
