GLOSSARY OF TABLE HEADINGS

Yield and Turnout

Yield - Pounds of lint harvested per acre.

Gin Turnout

Lint - Percentage of lint of the stripper-harvested cotton.

Seed - Percentage of seed of the stripper-harvested cotton.

Agronomic Properties - Determined from hand-snapped samples.

Percent Lint

Picked - Lint fraction of seed cotton.

Pulled - Lint fraction of burr cotton.

Boll Size - Weight, in grams, of seed cotton per boll.

Seed Index - Weight, in grams, of 100 fuzzy seed.

Lint Index - Weight, in grams, of lint from 100 seed (calculated).

Seed Per Boll - Average number of seed per boll (calculated).

Maturity and Storm Resistance

Percent Open Bolls - Percentage of open bolls on a given date.

Storm Resistance - Visual rating from 1 (very loose boll type, considerable seed cotton loss) to 5 (very tight boll types, no seed cotton loss).

Statistical Analysis

Mean - The average value for the trait being observed.

C.V.,% - Coefficient of variation. A statistical measure of the variability within a test, and expressed as percentage.

LSD - Least significant difference. If the difference between two means exceed this value, the two means are significantly different at the 0.05 probability level.

Fiber Properties - Measured by High Volume Instrument (HVI)

Micronaire - A relative measure of fiber linear density (mass per unit length) determined by air permeability.

Market Value	HVI Micronaire
Discount range	3.4 and below
Base range	3.5 - 3.6
Premium range	3.7 - 4.2
Base range	4.3 - 4.9
Discount range	5.0 and above

Length - An instrument measure of fiber length, expressed in hundredths of a inch, which approximates the classer's staple length.

Staple 32nds	HVI Length
30	.93 - .95
31	.96 - .98
32	.99 - 1.01
33	1.02 - 1.04
34	1.05 - 1.07
35	1.08 - 1.10
36	1.11 - 1.13
37	1.14 - 1.17
38	1.18 - 1.20

Uniformity - A measure of the uniformity of fiber length in a sample, expressed as a percentage.

Uniformity group	HVI Uniformity
Very high	86 and above
High	83 - 85
Intermediate	80 - 82
Low	77 - 79
Very Low	76 and below

Strength - The force required to rupture (or break) a fiber sample, expressed in grams per tex.

Strength group	HVI Strength
Very strong	31 and above
Strong	29 - 30
Intermediate	26 - 28
Weak	24 - 25
Very weak	23 and below

Elongation - The amount that a fiber sample will stretch prior to breakage. This is a measure of the deformation of fiber at rupture expressed as percent change in length based on the original fiber length.

Leaf Grade - The percentage of the fiber sample area covered by non-fiber materials, as determined by a video scanner. The percentage is converted to units from one through eight and the higher values indicate more foreign material.

Rd - Degree of reflectance. This measures how light or dark the fiber sample is, expressed as a percentage. Lower Rd values indicate a grayer sample.

+b - Yellowness. This measures the degree of color pigmentation. Higher +b value indicate yellower samples.

Color Grade - A function of the Rd and +b of the fiber sample. The color grade indicates the quadrant of the Nickerson-Hunter cotton colorimeter diagram in which Rd and +b values intersect.

See Exhibit A on page 10.

Percent Root Necrosis - This is the percentage of the root system that is diseased.
