  11. SD-VIG1 (MINSDLGVIG) MINIMUM SEEDLING VIGOR
  12. SPRG-VG1 (MINSPRGVIG) MINIMUM SPRING VIGOR
  13. SPRING VIGOR (SPRG_VIGOR) Visual estimate of amount of vegetative growth of biennial sweetclover three to four weeks after growth starts in the second year, coded 1-9.
Category: INSECT
  1. SCA-RES (SCARES) PERCENT SWEETCLOVER APHID RESISTANCE
  2. WEEV-DMG (WEEVILDAM) % weevil defoliation damage. Data collected from 1963-66. An adjusted mean was used to correlate variations of % damage. Data taken on 6-7 wk old seedlings -NW Exp Sta, Crookston,MN
Category: MORPHOLOGY
  1. BLM-VIG1 (BLMVIG1) MINIMUM EARLY BLOOM VIGOR
  2. BLM-VIG2 (BLMVIG2) MAXIMUM EARLY BLOOM VIGOR
  3. FLOWER COLOR (FLWR_COLOR) FLOWER COLOR
  4. Maximum Desirability Rating (MAXDESIR) Maximum desirability: Rating based on overall appearance of the accession (Rater's opinion based on other accessions and checks being rated). Perennials: only 2nd year ratings used.
  5. LEAF-NO2 (MAXLEAFNUM) MAXIMUM LEAF NUMBER
  6. LEAF-SZ2 (MAXLFSIZE) MAXIMUM LEAF SIZE
  7. STEM-NO2 (MAXSTEMNUM) MAXIMUM STEM NUMBER
  8. STEM-SZ2 (MAXSTEMSIZ) MAXIMUM STEM SIZE
  9. Minimum Desirability Rating (MINDESIR) Minimum desirability: Rating based on overall appearance of the accession (Rater's opinion based on other accessions and checks being rated). Perennials: only 2nd year ratings used.
  10. LEAF-NO1 (MINLEAFNUM) MINIMUM LEAF NUMBER
  11. LEAF-SZ1 (MINLFSIZE) MINIMUM LEAF SIZE
  12. STEM-NO1 (MINSTEMNUM) MINIMUM STEM NUMBER
  13. STEM-SZ1 (MINSTEMSIZ) MINIMUM STEM SIZE
  14. SEEDLING COLOR (SEEDLGCOL) The percentage of seedlings with stem or leaf red coloring in a given sample size. Faint indistinct coloring can be recorded as intermediate green and explained in the comment field.
  15. PLANT SHAPE (SHAPE) The presence of a many-thin-stem trait that is desirable for forage. Reference: Kirk, L.E. 1931 Sci. Agr. 11:315-325.
Category: OTHER
  1. CORE SUBSET (CORE) A flag to indicate the accession is part of the core subset
Category: PHENOLOGY
  1. DURATION (DURATION) The length of time that the plants ordinarily live before flowering and death. The biennials require a cold treatment before flowering, while annuals do not.
  2. MATURITY DAY FOR HAY HARVEST (HAY_DAY) Maturity for hay forage harvest. For biennials, Julian day in the second year of growth when 50% of the plants have open flowers. For annuals, days after seeding when 50% of the plants have open flowers.
Category: PRODUCTION
  1. HUNDRED SEED WEIGHT (100SEEDWGT) The weight in grams of 100 seeds.
  2. SURV-PC2 (MAXPCTSURV) MAXIMUM PERCENT SURVIVAL
  3. SD-PROD2 (MAXSDPROD) MAXIMUM SEED PRODUCTION
  4. SURV-PC1 (MINPCTSURV) MINIMUM PERCENT SURVIVAL
  5. SD-PROD1 (MINSDPROD) MINIMUM SEED PRODUCTION
Category: STRESS

  2. WTR-INJ1 (MINPCTWIN) MINIMUM PERCENT WINTER INJURY
  3. STAND SURVIVAL 2ND YEAR (STAND2YR) The percent of original plants established in the summer that resume growth in the spring of the second year, for biennials only.
