Category: COMMENT
  1. COMMENT (COMMENT) Observations made by cooperators or curators while evaluating or regenerating germplasm. Usually these observations are not published and need verification.
Category: DISEASE
  1. PYTHIUM-GERM (PYTHIUM-GERM) Pythium tolerance. Germination rate under Pythium inoculation (P. aphanidermatum) as the percent of normal conditions. So, larger numbers indicate more tolerance,
  2. STEMPHYLIUM (STEMPHYLIUM) Resistance of spinach germplasm to Stemphylium vesicarium leaf spot. Leaf spot disease severity scored between 7 to 16 days of inoculation on a scale of 0 to 4 where 0 = no symptoms on leaves; 1 = 1 – 25% leaf area infected; 2 = 26 – 50% leaf area infected; 3 = 51 – 75% leaf area infected; and 4 = 76 – 100% leaf area infected.
  3. WHITE-RUST (WHITE-RUST) White rust resistance scale. The lower numbers are most resistant. See Horticulture Research, 2022, 9: uhac069 https://doi.org/10.1093/hr/uhac069
Category: FLWR-FRUIT
  1. THE FREQ. OF MONOECIOUS PLANTS (MONOECIOUS) The frequency of monoecious (with both male and female flowers) plants.
Category: GROWTH
  1. TALLNESS IN CM, BEFORE BOLTING (TALLNESS) Tallness of the leaves in cm. Measured at maturity for harvest as a vegetable, before the flowering stalk emerges. The leaves are held up and measured from the soil to the tallest leaf point.
Category: MORPHOLOGY
  1. COLORING AT THE BASE (BASE_COLOR) Coloring at the base of the petioles.
  2. LEAF ERECTNESS (ERECTNESS) Erectness of the leaves.
  3. LEAF BLADE SHADE OF GREEN (LEAF_COLOR) The shade of green of the leaf blade.
  4. LEAF BLADE SHAPE (LEAF_SHAPE) Leaf blade shapes.
  5. LEAF SURFACE, SAVOY TO FLAT (LEAF_SURF) Leaf blade surface texture, savoy (wrinkled) to flat.
  6. SEEDS IN CLUSTERS, FREQUENCY (SEED_CLUST) The percentage of combined seeds and seed units (clusters), in seed units of 2 or more seeds.
  7. SEEDS WITH SPINES, FREQUENCY (SEED_SPINE) The percentage of seeds with spines more than 2 mm long in a sample of seeds. This distinguishes seeds with spines from round seeds.
Category: PHENOLOGY
  1. FLOWERING STALK EMERGENCE (BOLTING) Relative time to bolting.
Category: PRODUCTION
  1. HUNDRED SEED WEIGHT (100SEEDWGT) The weight in grams of 100 seeds. Taken from the hundred seed weights in the GRIN inventory.
