Pea Database Collaboration Project/Pea Genetics
Until I or others have time, this is the best pea breeding information i can provide. This is my blog post on pea crossing. I'm working on restoring the non-working photos below.

Pea Traits Chromosome Table
| Pea Trait Name | Dominant / recessive | Locus / Chromosome | Notes | |
|---|---|---|---|---|
| Red-seeds (ruby) | rec | 0 | ||
| Astriatus (Astr) | DOM | 0 | Pods with short purple-violet longitudinal stripes. | |
| convex pods #1 (co) | rec | 0 | ||
| concave pods #2 | rec | 0 | ||
| dehiscent pod #3 | rec | 0 | ||
| “waxless pods” | Semi-Dom | 0 | ||
| Stringless-pods (sin) | rec | 0 | ||
| spotted pod #2 (rups) | rec | 0 | ||
| Obs | DOM | 0 | Violet patterns on testa from seed-genes F, Fs, U<st or pod-genes Pu, Pur enlarge to cover part of or entire testa, obscuratum. Vitality and high yield have often been found positively correlated with Obs. | |
| Purple Seed Testa (put) | rec | 0
Solid purple coloured testa, like U. |
||
| Nap gene (nap) | rec | 1 | ||
| orange cotyledons (Orc) | Semi-Dom | 1 | ||
| Purple-Pod gene #2 (Pur) | DOM | 1 | Purple pods when together with Pu. Four alleles reported: Pur, uniform purple; pur<a, major part purple; pur<b, less colour on pod, may limit colour to funiculus. Character can be variable in expression and unstable. Studies have show that a pigmented funiculus differentiates the presence of Pur from Pu (non-pigmented). | |
| Color inhibition (a) | rec | 1 | ||
| Hyper-tendtils (af) | rec | 1 | parsley pea with (tl) | |
| spotted pod #1 (rup) | rec | 1 | ||
| cotyledons green (I) | rec | 1 | ||
| Salmon-coloured testa | rec | 1 | ||
| Orange-pod (orp) | rec | 2 | ||
| Flower number #1 (fn) | rec | 2 | Increasing number of flowers per inflorescence. Fn Fna is one-flowered; Fn fna and fn Fna two flowered; fn fna three-to several flowered. See also fna. | |
| Purple-Pod gene #1 (Pu) | DOM | 3 | Together with Pur purple pods, expression requires A. Pu Pur A Am B Gp purple pod; Pu Pur A and am or b or gp red pods. | |
| Pink Color (b) | rec | 3 | ||
| dehiscent pod #2 | DOM | 3 | ||
| twisted pod (twp) | rec | 3 | ||
| Dwarf-ism (le) | rec | 3 | ||
| Violet Spots on Seeds (F) | DOM | 3 | ||
| Brown Marbling Seeds (Maple) (M) | DOM | 3 | ||
| Pod-wall fiber gene #2 (v) | rec | 4 | P V normal parchmented pod; p V strip of sclerenchyma; P v inner membrane reduced to patches of sclerenchyma; p v entirely without parchment. | |
| convex pods #2 (con) | rec | 4 | ||
| Snap-pod thicknes (n) | rec | 4 | ||
| “Crown Pea” (fa) | rec | 4 | Fasciated plants. Expression variable. | |
| Flower number #2 (fna) | rec | 4 | Increasing number of flowers per inflorescence. Fn Fna is one-flowered; Fn fna and fn Fna two flowered; fn fna three-to several flowered. See also fna. | |
| Violet-seeds (U) | DOM | 5 | Testa uniform violet, U, with violet stripes, U<st, non- violet, u. The colour of U varies from almost black to brownish. | |
| Yellow-pods (gp) | rec | 5 | New growth, peduncles and sepals often yellowish so character may be discerned before pods develop. | |
| Tendriless (tl) | rec | 5 | parsley pea with (af) | |
| concave pods #1 | rec | 5 | ||
| dehiscent pod #1 | DOM | 5 | ||
| pointy pod tip (bt) | rec | 5 | ||
| wrinkled seeds (r) | rec | 5 | ||
| determinate (det) | rec | 5 | ||
| Constricted pods (cotr? Laf? Te?) | rec | 5 | ||
| Pod fiber gene #1 (p) | rec | 6 | P V normal parchmented pod; p V strip of sclerenchyma; P v inner membrane reduced to patches of sclerenchyma; p v entirely without parchment. | |
| large pod (lt) | rec | 6 | Increases width of pod about 25%. | |
| long pod / many seeds (canoe) | ? | ? | ||
| branching (ramosus) | rec | 5,5,7,7,2,1,3 |
