Stages of Development

Vegetative stages of determinate and indeterminate dry bean.
Stage No.General DescriptionDays from Planting
VE Hypocotyl emergence (crook stage) 7-8
VC Cotyledon (seed leaves) and unifoliolate leaves visible 8-9
V1 First fully developed trifoliolate at the third node 10
V2 Second trifoliolate (count when leaf edges no longer touch) 19
V3 Third trifoliolate (secondary branching begins to show in leaf axils) 29
V(n) Nth trifolioate, but with blossom clusters still not visibly opened A new node every 3 to 5 days
V5 Bush (determinate) plants may begin to exhibit blossom and become stage R1 50
V8 Vine (indeterminate) plants bay begin to exhibit blossom and become stage R1 40

 

Determinate bush reproductive stages.
Stage No.General DescriptionDays from Planting
R1 One blossom open at any node 50
R2 Pods 1/2 inch long at first blossom position (usually node 2 to 3) 53
R3 Pods 1 inch long at first blossom position; secondary branching at all nodes, so plant is becoming denser but not taller, 1/2 bloom 56
R4 Pods 3 inches long (seeds not discernible; bush types may be shorter) 59
R5 Pods 3 to 4 inches (seed discernible) 64
R6 Seeds at least 1/4 inch over long axis 66
R7 Oldest pods have developed seeds (other parts of plant will have full-length pods with seeds almost as large as first pods; pods will be developed over the whole plant) 72
R8 Leaves yellowing over half of plant, very few small pods may be drying (point of maximum production has been reached) 90
R9 Mature, at least 80% of pods showing yellow and mostly ripe; only 40% of leaves still green 105


Indeterminate vining plant reproductive stages.
Stage No.General DescriptionDays from Planting
R1 One blossom open at any nodes; tendril will begin to show 40
R2 Pods 1/2 inch long at first blossom position (node 2 to 5 in most plants); blossom would have just sloughed 43
R3 Pods 1 inch long at first blossom position; pods are showing at higher nodes when blossom sloughs, 1/2 bloom 46
R4 Pods 2 inches long at first blossom position 50
R5 Pods more than 3 inches long, seeds discernible by feel 56
R6 Pods 4.5 inches long with spurs (maximum length); seeds at least 1/4 inch long axis 60
R7 Oldest pods have fully developed green seeds (other parts of plant will have full-length pods with seeds near same size; pods to the top and blossom on tendril, nodes 10 to 13) 70
R8 Leaves yellowing over half of plant, very few small new pods/blossom developing, small pods may be drying (point of maximum production has been reached) 82
R9 Mature, at least 80% of the pods showing yellow and mostly ripe; only 30% of leaves are still green 94
