Lentil growth stages

Development phase	Growth stage (GS)	Description
G Germination	GS G0 Dry seed
	GS G1 Imbibed seed
	GS G2 Radicle apparent
	GS G3 Plumule and radicle apparent
	GS G4 Emergence
V Vegetative	GS V1 First node	First leaf fully unfolded with one pair leaflets
	GS V(x) x First node	X leaf fully unfolded with more than one pair of leaflets, complex tendril
	GS V(n) n, last recorded node	n - any number of nodes on the main stem with fully unfolded leaves according to the cultivar
R Reproductive	GS R1 First bloom	One open flower at any node
	GS R2 Full bloom	Flower open or has opened on nodes 10 to 13 of the basal primary branch
	GS R3 Early pod	Pods on nodes 10 to 15 of the basal primary branch visible
	GS R4 Flat pod	Pods on nodes 10 to 15 of the basal primary branch has reached its full length and is largely flat. Seeds fill less than half of the pod area but can be felt as a bump between the fingers
	GS R5 Full seed	Seed on any single pod on nodes 1 to 13 of the basal primary branch are swollen and completely fill the pod cavity
	GS R6 Full pod cavities	At all the normal pods on nodes 10 to 13 of the basal primary branch are swollen and completely fill the pod cavity
	GS R7 Physiological maturity	The leaves start yellowing and 50% of the pods have turned yellow
	GS R8 Full maturity	90% of the pods on the plant are golden brown
