  7. E1 (E1) The percentage elongation at break of the center 1/8 inch of the fiber bundle measured for T1 strength on the Stelometer.
  8. Embryo Percentage (EMBRYO) Weight of embryo over weight of whole seed.
  9. Embryo Index (EMBRYOIND) Weight in grams of embryos per 100 seeds.
  10. Flower Score (FLOWERSCOR) Flowering score of TX Collection. (0.0 = no flowers during growing season, 1.0 = flowers 8 weeks later than Upland var. 5.0 = flowers as early as Upland variety).

  13. Leaf Hairs (LEAFHAIRS) Leaf hairs.
  14. Leaf Lac (LEAFLAC) B/A where B = distance from petiole to the sinus between the middle lobe and the first lateral lobe and A = length of leaf from petiole to tip of middle lobe.
  15. Locules/Boll (LOCULES) Average number of locules in a 10 boll sample.
  16. Petal Color (PETALCOLOR) Petal color.
  17. Petal Spot (PETALSPOT) Type of petal spotting. For the Arizona Collections the codes are from 0 (spotless) to 22 (full spot).
  18. Pollen Color (POLLENCOL) Pollen color.
  19. Pubescence (PUBESCENCE) Hairiness of plant in general.
  20. Reflectance (REFLECT) A Measure of the percentage of reflectance on a Nickerson-Hunter Colorimeter. The higher the value the lighter the cotton.
  21. Seed Coat Index (SDCOATIND) Weight in grams of seed coats per 100 seeds.
  22. Seed Coat Percentage (SEEDCOAT) Weight of seed coat over weight of whole seed.
  23. Seeds/Boll (SEEDS) Average number of seed in a 10 boll sample.
  24. Seed Type (SEEDTYPE) Seed type code.
  25. 2.5% Span Length (SPANLEN25) The length (mm) at which the given percentage of fibers in an array are that long or longer.
  26. 50% Span Length (SPANLEN50) The length (mm) at which the given percentage of fibers in an array are that long or longer.
  27. Uhm (UHM) The length in inches of the half of the fibers by weight that contains the longer fibers. UHM approximates classer's staple and 2.5 percent span length.
  28. UHM2 (UHM2) UHM2
  29. Yellowness (YELLOWNESS) Hunter's B value, a measure of increasing yellowness of the cotton, taken with a Nickerson-Hunter Colorimeter.
