| VE | Emergence | Cotyledons above the soil surface. |
| VC | Cotyledon | Unifoliate leaves unrolled sufficiently so the leaf edges are not touching. |
| V1 | First-node | Fully developed leaves at unifoliate nodes. |
| V2 | Second-node | Fully developed trifoliate leaf at node above the unifoliate nodes. |
| V3 | Third-node | Three nodes on the main stem with fully developed leaves beginning with the unifoliate nodes. |
| V(n) | nth-node | n number of nodes on the main stem with fully developed leaves beginning with the unifoliate nodes. n can be any number beginning with 1 for V1, first-node stage. |
| R1 | Beginning bloom | One open flower at any node on the main stem. |
| R2 | Full bloom | Open flower at one of the two uppermost nodes on the main stem with a fully developed leaf. |
| R3 | Beginning pod | Pod 3/16 inch (5 mm) long at one of four uppermost nodes on the main stem with a fully developed leaf. |
| R4 | Full pod | Pod 3/4 inch (2 cm) long at one of the four uppermost nodes on the main stem with a fully developed leaf |
| R5 | Beginning seed | Seed 1/8 inch (3 mm) long in a pod at one of the four upper-most nodes on the main stem with a fully developed leaf. |
| R6 | Full seed | Pod containing a green seed that fills the pod cavity at one of the four uppermost nodes on the main stem with a fully developed leaf. |
| R7 | Beginning maturity | One normal pod on the main stem that has reached its mature pod color. |
| R8 | Full maturity | Ninety-five percent of the pods that have reached their mature pod color. Five to 10 days away from 15% moisture. |
