Some reports show that, tomato with disease resistance ability by vertical resistance have been developed and are effective (at least initially) in avoiding growth and development of pathogen to the crop.
In comparison to vertical resistance, race-nonspecific resistance is often controlled by several genes or quantitative trait loci (QTLs), which is partial resistance against multiple races of the pathogen.
[W.sub.5](s) = [D.sub.15]/[D.sub.0]--transfer function of the vertical resistance
reaction of the agricultural implement relative to the oscillations of the rear part of the body of the wide span tractor (vehicle),
For medium- and low-speed penetration, the horizontal resistance force , the vertical resistance
force [18,19], the jamming and the fluctuations of the resistance force , and the shape effects on the resistance force  were studied.
Sunflower breeding for resistance to broomrape has been nearly exclusively based on the utilization of major genes conferring qualitative or vertical resistance
, which is rapidly overcome by the parasite.
demissum, belong to the "vertical resistance
When the oil-based mud level rose to level one, all of the vertical resistances
started to decline to the 35 to 60 k[ohm] range.
